This uses a static lbs_cmd_async_callback function, which is a
noop. Just setting the callback argument to __lbs_cmd_async()
to NULL won't work, because then the cmdnode wouldn't be
released.
This also makes __lbs_cmd_async() a static method, which is
now only used by lbs_cmd() and lbs_cmd_async().

Neither CMD_802_11_PAIRWISE_TSC nor CMD_802_11_GROUP_TSC is used or

As reported by Johannes Berg:
I started getting this warning with recent kernels:
[ 773.908927] ------------[ cut here ]------------
[ 773.908954] Badness at net/core/dev.c:2204
...
If we loop more than once in gem_poll(), we'll
use more than the real budget in our gem_rx()
calls, thus eventually trigger the caller's
assertions in net_rx_action().
Subtract "work_done" from "budget" for the second
arg to gem_rx() to fix the bug.

lockdep warns of locking order while using ifb with sch_ingress and

a different device (e.g. from eth) and has its own pair of queue
locks. (This warning is a false-positive in common scenario of using
ifb; yet there are possible situations, when this order could be
dangerous; lockdep should warn in such a case.) (With suggestions by

This is a critical patch which adds a workaround for a HW bug. The patch
will limit the number of outstanding tx packets to 16. Otherwise, the HW
could send out packets with bad checksums.
The driver will still setup the tx packets into the ring, however, will
only set the Valid bit on 16 packets at a time.

The last change in the Tx queue stop mechanism opens a window
where the Tx queue might be stopped after pending credits
returned.
Tx credits are returned via a control message generated by the HW.
It returns tx credits on demand, triggered by a completion bit
set in selective transmit packet headers.
The current code can lead to the Tx queue stopped
with all pending credits returned, and the current frame
not triggering a credit return. The Tx queue will then never be
awaken.
The driver could alternatively request a completion for packets
that stop the queue. It's however safer at this point to go back
to the pre-existing behaviour.

This patch should resolve a problem that's troubled support for
some RNDIS peripherals. It seems to have boiled down to using a
variable to establish transfer size limits before it was assigned,
which caused those devices to fallback to a default "jumbogram"
mode we don't support. Fix by assigning it earlier for RNDIS.

Problem Description and Fix
---------------------------
When a pause packet(with destination as reserved Multicast address) is
received by the EMAC hardware to control the flow of frames being
transmitted by it, it is dropped by the hardware unless the reserved
Multicast address is hashed in to the GAHT[1-4] registers. This code fix
adds the default reserved multicast address to the GAHT[1-4] registers
in the EMAC(s) present on the chip. The flow control with Pause packets
will only work if the following register bits are programmed in EMAC:
EMACx_MR1[APP] = 1
EMACx_RMR[BAE] = 1
EMACx_RMR[MAE] = 1
Behavior that may be observed in a running system
-------------------------------------------------
A host transferring data from a PPC based system may send a Pause packet
to the PPC EMAC requesting it to slow down the flow of packets. If the
default reserved multicast MAC address is not programmed into the
GAHT[1-4] registers this Pause packet will be dropped by PPC EMAC and no
Flow Control will be done.

The problem can be triggered with a high amount of host->guest traffic.
I think its the following race:
poll says netif_rx_complete
poll calls enable_cb
enable_cb opens the interrupt mask
a new packet comes, an interrupt is triggered----\
enable_cb sees that there is more work |
enable_cb disables the interrupt |
. V
. interrupt is delivered
. skb_recv_done does atomic napi test, ok
some waiting disable_cb is called->check fails->bang!
.
poll would do napi check
poll would do disable_cb
The fix is to let enable_cb not disable the interrupt again, but expect the
caller to do the cleanup if it returns false. In that case, the interrupt is
only disabled, if the napi test_set_bit was successful.
