2010-12-16net: Fix drivers advertising HW_CSUM feature to use csum_startMichał Mirosław
Some drivers are using skb_transport_offset(skb) instead of skb->csum_start for NETIF_F_HW_CSUM offload. This does not matter now, but if someone implements checksumming of encapsulated packets then this will break silently. TSO output paths are left as they are, since they are for IP+TCP only (might be worth converting though). Signed-off-by: Michał Mirosław <mirq-linux@rere.qmqm.pl> Signed-off-by: David S.

2010-12-12sungem: update gp->reset_task flushingTejun Heo
gp->reset_task_pending is always set right before reset_task is scheduled and as there is no synchronization between the setting and scheduling, busy looping on reset_task_pending before flushing reset_task doesn't really buy anything. Directly flush gp->reset_task on suspend and cancel on detach. Signed-off-by: Tejun Heo <tj@kernel.org> Cc: "David S. Miller" <davem@davemloft.net> Cc: netdev@vger.kernel.org

2010-05-14drivers/net: Remove unnecessary returns from void function()sJoe Perches
This patch removes from drivers/net/ all the unnecessary return; statements that precede the last closing brace of void functions. It does not remove the returns that are immediately preceded by a label as gcc doesn't like that. It also does not remove null void functions with return. Done via: $ grep -rP --include=*.[ch] -l "return;\n}" net/ | \ xargs perl -i -e 'local $/ ; while (<>) { s/\n[ \t\n]+return;\n}/\n}/g; print; }' with some cleanups by hand.

2010-03-30include cleanup: Update gfp.h and slab.h includes to prepare for breaking ↵Tejun Heo
implicit slab.h inclusion from percpu.h percpu.h is included by sched.h and module.h and thus ends up being included when building most .c files. percpu.h includes slab.h which in turn includes gfp.h making everything defined by the two files universally available and complicating inclusion dependencies. percpu.h -> slab.h dependency is about to be removed. Prepare for this change by updating users of gfp and slab facilities include those headers directly instead of assuming availability. As this conversion needs to touch large number of source files, the following script is used as the basis of conversion. http://userweb.kernel.org/~tj/misc/slabh-sweep.py The script does the followings. * Scan files for gfp and slab usages and update includes such that only the necessary includes are there. ie. if only gfp is used, gfp.h, if slab is used, slab.h. * When the script inserts a new include, it looks at the include blocks and try to put the new include such that its order conforms to its surrounding. It's put in the include block which contains core kernel includes, in the same order that the rest are ordered - alphabetical, Christmas tree, rev-Xmas-tree or at the end if there doesn't seem to be any matching order. * If the script can't find a place to put a new include (mostly because the file doesn't have fitting include block), it prints out an error message indicating which .h file needs to be added to the file. The conversion was done in the following steps. 1. The initial automatic conversion of all .c files updated slightly over 4000 files, deleting around 700 includes and adding ~480 gfp.h and ~3000 slab.h inclusions. The script emitted errors for ~400 files. 2. Each error was manually checked. Some didn't need the inclusion, some needed manual addition while adding it to implementation .h or embedding .c file was more appropriate for others. This step added inclusions to around 150 files. 3. The script was run again and the output was compared to the edits from #2 to make sure no file was left behind. 4. Several build tests were done and a couple of problems were fixed. e.g. lib/decompress_*.c used malloc/free() wrappers around slab APIs requiring slab.h to be added manually. 5. The script was run on all .h files but without automatically editing them as sprinkling gfp.h and slab.h inclusions around .h files could easily lead to inclusion dependency hell. Most gfp.h inclusion directives were ignored as stuff from gfp.h was usually wildly available and often used in preprocessor macros. Each slab.h inclusion directive was examined and added manually as necessary. 6. percpu.h was updated not to include slab.h. 7. Build test were done on the following configurations and failures were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my distributed build env didn't work with gcov compiles) and a few more options had to be turned off depending on archs to make things build (like ipr on powerpc/64 which failed due to missing writeq). * x86 and x86_64 UP and SMP allmodconfig and a custom test config. * powerpc and powerpc64 SMP allmodconfig * sparc and sparc64 SMP allmodconfig * ia64 SMP allmodconfig * s390 SMP allmodconfig * alpha SMP allmodconfig * um on x86_64 SMP allmodconfig 8. percpu.h modifications were reverted so that it could be applied as a separate patch and serve as bisection point. Given the fact that I had only a couple of failures from tests on step 6, I'm fairly confident about the coverage of this conversion patch. If there is a breakage, it's likely to be something in one of the arch headers which should be easily discoverable easily on most builds of the specific arch.

2009-02-06sungem: Soft lockup in sungem on Netra AC200 when switching interface upIlkka Virta
From: Ilkka Virta <itvirta@iki.fi> In the lockup situation the driver seems to go off in an eternal storm of interrupts right after calling request_irq(). It doesn't actually do anything interesting in the interrupt handler. Since connecting the link afterwards works, something later in initialization must fix this. Looking at gem_do_start() and gem_open(), it seems that the only thing done while opening the device after the request_irq(), is a call to napi_enable(). I don't know what the ordering requirements are for the initialization, but I boldly tried to move the napi_enable() call inside gem_do_start() before the link state is checked and interrupts subsequently enabled, and it seems to work for me. Doesn't even break anything too obvious... Signed-off-by: David S. Miller <davem@davemloft.net>

2008-12-09sungem: improve ethtool output with internal pcs and serdesHermann Lauer
From: Hermann Lauer <Hermann.Lauer@iwr.uni-heidelberg.de> Attached is a patch which improves the output of ethtool (see below) to some sensefull values with a sungem fibre card which uses the sungem interal pcs connected to a serdes chip. The seriallink case in the driver is untouched. Most values are hardcoded, because gigabit fibre autoneg is anyways limited and the driver don't really support much at the moment with that hardware.

2008-12-09sungem: Make PCS PHY support partially work again.David S. Miller
As reported by Hermann Lauer, PCS PHY support in the sungem driver simply doesn't work. When the chip is reset due to open, or some other similar operation, the PCS is reset too but we don't program it back into a running state. The result is no link when the device is brought up. This partially rectifies the situation for the moment, by kicking the PCS after a sungem chip reset so that it will renegotiate and be re-enabled again. The behavior is still a little bit dodgy as the added renegotiate make the link take some time after bringing the interface up, but this is a significant improvement in that things actually work now :-) Based almost entirely upon an initial patch by Hermann.

2008-11-12netdevice: safe convert to netdev_priv() #part-3Wang Chen
We have some reasons to kill netdev->priv: 1. netdev->priv is equal to netdev_priv(). 2. netdev_priv() wraps the calculation of netdev->priv's offset, obviously netdev_priv() is more flexible than netdev->priv. But we cann't kill netdev->priv, because so many drivers reference to it directly. This patch is a safe convert for netdev->priv to netdev_priv(netdev). Since all of the netdev->priv is only for read. But it is too big to be sent in one mail. I split it to 4 parts and make every part smaller than 100,000 bytes, which is max size allowed by vger.

Commit bea3348e (the NAPI changes) made sungem unconditionally enable NAPI when resuming and unconditionally disable when suspending, this, however, makes napi_disable() hang when suspending when the interface was taken down before suspend because taking the interface down also disables NAPI. This patch makes touching the napi struct in suspend/resume code paths depend on having the interface up, thereby fixing the hang on suspend.
