2008-01-28libertas: clean up direct command handlingDan Williams
Move direct command handling through __lbs_cmd() over to using the header as the first member of the command structure, and only define the __lbs_cmd() callback in one place rather than 3. Convert boot2 version command to new usage. Signed-off-by: Dan Williams <dcbw@redhat.com> Signed-off-by: David Woodhouse <dwmw2@infradead.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2008-01-28libertas: don't run thread while firmware not yet readyDavid Woodhouse

2008-01-28libertas: switch to a waitqueue and timer for handling USB firmware loadDavid Woodhouse
No need to busy-wait, even if we did have a 100ms delay in the loop. This makes it easier to support the new 'firmware ready' event which is in the new firmware, too. Signed-off-by: David Woodhouse <dwmw2@infradead.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2008-01-28libertas: improve reliability of firmware reloading on USBDavid Woodhouse
Increase the delay between issuing the RESET command and the usb reset, and be prepared to discard more than one 'normal' packet from it before it resets. Signed-off-by: David Woodhouse <dwmw2@infradead.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2008-01-28libertas: make rtap and normal modes mutually exclusive, clean up open/stopDavid Woodhouse
Signed-off-by: David Woodhouse <dwmw2@infradead.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2008-01-28libertas: clean up is_command_allowed_in_ps()Dan Williams
Total overkill to have an array when there's only one command in it. Signed-off-by: Dan Williams <dcbw@redhat.com> Signed-off-by: David Woodhouse <dwmw2@infradead.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2008-01-28libertas: remove pre_open_check()David Woodhouse
The firmware is always initialised before we register the netdevices. It's not possible for pre_open_check() to fail. One day we might try loading firmware in ->open(), but still it won't be just a _check_, like this. Signed-off-by: David Woodhouse <dwmw2@infradead.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2008-01-28libertas: make lbs_cmd() usage nicerDan Williams
Define a macro that relieves the caller from having to use sizeof on the command structure when calling lbs_cmd(), and move the prototype of __lbs_cmd() to a new cmd.h file.

2008-01-28libertas: clean up lbs_interrupt()David Woodhouse
Make it take struct lbs_private as argument; that's all it wants anyway, and all callers were starting off from that. Don't wake the netif queues, because those should be handled elsewhere. And sort out the locking, with a big nasty warning for those who don't have the driver_lock locked when they call it. Oh, and fix if_cs.c to lock the driver_lock before calling it.

2008-01-28libertas: add opaque extra argument to cmd callback functionDavid Woodhouse
This will be useful for letting callbacks do stuff like copying the response into a buffer provided by the caller of lbs_cmd() Signed-off-by: David Woodhouse <dwmw2@infradead.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2008-01-28libertas: fix use-after-free errorHolger Schurig
Previously, the display of subscribed events could be wrong. Signed-off-by: Holger Schurig <hs4233@mail.mn-solutions.de> Signed-off-by: David Woodhouse <dwmw2@infradead.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2008-01-28libertas: kill (IS,SET,UNSET)_MESH_FRAME.David Woodhouse
No need for these any more. We've collapsed all the unneeded nests of functions which needed to keep track of which device the skb belonged to. Signed-off-by: David Woodhouse <dwmw2@infradead.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2008-01-28libertas: kill lbs_upload_tx_packet()David Woodhouse
It replaces two lines of code. And even for those it has to make inferences about things (i.e. which device) which the caller would have just known. Signed-off-by: David Woodhouse <dwmw2@infradead.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2008-01-28libertas: fix error cases in lbs_process_rxed_802_11_packet()David Woodhouse
Signed-off-by: David Woodhouse <dwmw2@infradead.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2008-01-28libertas: remove unreachable code from process_rxed_802_11_packet()David Woodhouse
The function is only ever called if we're in rtap mode. So the bit in it which is conditional on rtap mode seems a little superfluous. Signed-off-by: David Woodhouse <dwmw2@infradead.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2008-01-28libertas: Move actual transmission to main threadDavid Woodhouse
The locking issues with TX, especially TX from multiple netdevs, get _so_ much easier if you do it like this. Signed-off-by: David Woodhouse <dwmw2@infradead.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2008-01-28libertas: refactor the 'should I sleep?' decision in lbs_thread()David Woodhouse
This was making my brain hurt. Signed-off-by: David Woodhouse <dwmw2@infradead.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2008-01-28libertas: free successfully transmitted skbs againDavid Woodhouse
I was so busy cleaning up the failure modes that I accidentally forgot to make sure we still free them in the success case. Oops. Signed-off-by: David Woodhouse <dwmw2@infradead.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2008-01-28libertas: TX packet is radiotap iff it comes from rtap_devDavid Woodhouse
Fix one of the barriers to simultaneous radiotap and normal operation -- stop misinterpreting the TX packets on the normal devices. We're also going to have to clone the incoming skbs and feed them into both devices, and there seem to be firmware problems with staying associated too. But this is a reasonable start... Signed-off-by: David Woodhouse <dwmw2@infradead.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2008-01-28libertas: set dev_addr on rtap deviceDavid Woodhouse
This lets us bring it up, because eth_validate_addr() succeeds instead of returning -EINVAL. And finally monitor mode seems to (mostly) work. Signed-off-by: David Woodhouse <dwmw2@infradead.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2008-01-28libertas: stop using ieee80211 for radiotap deviceDavid Woodhouse
There seems to be no point in doing it as an ieee80211 device instead of a normal netdev, and when we override its ->priv and then call free_ieee80211() it has a distressing tendency to crash horribly. Signed-off-by: David Woodhouse <dwmw2@infradead.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2008-01-28libertas: kill lbs_pre_start_xmit(), lib_mesh_pre_start_xmit()David Woodhouse
These wrappers only do two things. Firstly, they set the frame type, which isn't necessary since lbs_hard_start_xmit() gets to see which device it belongs to anyway. Secondly, they return -EOPNOTSUPP if the device is in monitor mode. Which is a strange thing to do and will provide nasty warnings from qdisc_restart(). And lbs_hard_start_xmit() seems to have code to cope with monitor mode anyway. Signed-off-by: David Woodhouse <dwmw2@infradead.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2008-01-28libertas: clean up lbs_hard_start_xmit()David Woodhouse
Having merged the nest of functions into one, now we can clean it up and fix the error handling, and the duplication -- and at least make a start on the locking. Signed-off-by: David Woodhouse <dwmw2@infradead.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>

2008-01-28libertas: kill SendSinglePacket() function.David Woodhouse
Make a start on reducing the number of pointless nested functions, starting with the StudlyCaps. No semantic changes (yet) -- we can sort out the now-obvious discrepancy in the failure paths in a separate commit. Signed-off-by: David Woodhouse <dwmw2@infradead.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2008-01-28libertas: kill internal tx queue for PS modeDavid Woodhouse
It was buggy as hell anyway, since it was just spewing packets at the device when it wasn't necessarily ready for them (in the USB case, while the URB was still busy). We could probably do with a better way of flushing packets to the device _immediately_, before we stick it back into sleep mode. But we can no longer just dequeue packets directly, it seems. Signed-off-by: David Woodhouse <dwmw2@infradead.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2008-01-28libertas: stop debugfs code looking at cmdpendingqDavid Woodhouse
It doesn't need to wait until no commands are pending anyway -- it only needs to wait until the scan is finished. We can hopefully find it something else to wait on too -- it's the only user of the cmd_pending waitqueue. Signed-off-by: David Woodhouse <dwmw2@infradead.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>

2008-01-28libertas: kill struct lbs_adapterDavid Woodhouse
There seems to be no reason for a separate structure; move it all into struct lbs_private. Signed-off-by: David Woodhouse <dwmw2@infradead.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2008-01-28libertas: kill TxLockFlagDavid Woodhouse
We don't need this. We can use adapter->currenttxskb instead. Signed-off-by: David Woodhouse <dwmw2@infradead.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2008-01-28libertas: fix lbs_rtap attribute in sysfsDavid Woodhouse
At least it doesn't oops when you attempt to read or write it now. Only when you enable it and then later turn it off. And when it's enabled I don't see how it actually works. But one fewer oops is good, for now... Signed-off-by: David Woodhouse <dwmw2@infradead.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>

2008-01-28libertas: switch lbs_cmd() to take a callback function pointerDavid Woodhouse
All existing code which sends commands is set up to have some function called with the results, not to get data back. It's more versatile this way, and providing it with a callback function which involves memcpy() is hardly difficult. Signed-off-by: David Woodhouse <dwmw2@infradead.org> Signed-off-by: John W.

2008-01-28libertas: endianness fixesHolger Schurig
Recently I found that that sparse by default doesn't endianness checks. So I changed my compilation habit to be make modules C=1 SUBDIRS=drivers/net/wireless/libertas CHECKFLAGS="-D__CHECK_ENDIAN__" so that I get the little-endian checks from sparse as well. That showed up a good bunch of problems. Signed-off-by: Holger Schurig <hs4233@mail.mn-solutions.de> Signed-off-by: David Woodhouse <dwmw2@infradead.org> Signed-off-by: John W.

2008-01-28libertas: implement new scanning logicHolger Schurig
This changes the code that is used for scanning and makes it hopefully easier to understand: * move function into logical blocks * create a bunch of lbs_scan_add_XXXX_tlv() functions, that help to create the TLV parameter of CMD_802_11_SCAN * all of them are now called from the much simpler lbs_do_scan() * no **puserscancfg double-pointers :-) Signed-off-by: Holger Schurig <hs4233@mail.mn-solutions.de> Acked-by: Dan Williams <dcbw@redhat.com> Signed-off-by: David Woodhouse <dwmw2@infradead.org> Signed-off-by: John W.

2008-01-28libertas: fix data packet size errorsHolger Schurig
I wondered about junk bytes at the end when using "lbsdebug +hex +host" until I noticed that firmware for the CF card sends my extranous bytes. It says "I have 20 bytes", I take 20 bytes, but the last 8 bytes of this are just data junk. Also, in the new lbs_cmd() where was a size miscalulation that made itself clear after fixing this bug.
