The commit "ath9k_hw: Fix incorrect key_miss handling" changed the code
to only report key miss errors if a MIC error wasn't reported.
When checking the flags in that order in the MAC code, it might miss some
real events, because the value of the MIC error flag is undefined under
some conditions.
The primary issue addressed by the previous commit is making sure that
MIC errors are properly reported on the STA side. This can be fixed in
a better way by adding a separate rx status flag for key miss and
ignoring it for multicast frames.
This fix slightly improves stability in AP mode on some older hardware,
like AR9132.

This patch verifies that the length of a buffer stored in a linked list

If the size is larger than a max size of a skb, it means that we shouldn't
go ahead building skbs anyway since we won't be able to send the buffer as

There is a problem in the ixgbe driver with the reporting of the flow
control parameters. The autoneg parameter is shown to be of if
*either* it really is off, or current modes for both tx and rx are off.
The problem is seen when the parameters are read or set when the link
is down. In this case, the driver sees that tx and rx are currently off
and therefore autoneg parameter is incorrectly reported to be off too.
Also, the ethtool binary can not set the autoneg off since it sees that
it already is. When a link later comes up, the autonegotiation is
carried out normally and the driver later on reports the autoneg
parameter to be on (as it is) and then it can also be changed with
ethtool.
The patch is made against v3.0 kernel, but the problem seems to be there
since v2.6.30-rc1.
Reviewer comments: What we are trying to do is to disable flow control
while the cable is disconnected. Since ixgbe defaults to full flow
control, we call ethtool -A autoneg off rx off tx off while the cable
is disconnected. This doesn't work, because the driver sets
hw->fc.current_mode = ixgbe_fc_none if the cable is unplugged.
ixgbe_get_pauseparam() then reports to ethtool that nothing needs to be
done. The code fixes this, but it might have some unknown consequences.

Also, add the option for peer to peer DMA MPS configuration. Peer to

prevent it from working by having the MPS on one root port different
than the MPS on another. To work around this, simply make the system

Recent patches added support for resetting the SD8686 hardware when
commands time out, which seems to happen quite frequently soon after
resuming the system from a Wake-on-WLAN-triggered resume.
At http://dev.laptop.org/ticket/10969 we see the same thing happen
with transmits. In this case, the hardware will fail to respond to
a frame passed for transmission, and libertas (correctly) will block
all further commands and transmissions as the hardware can only
deal with one thing at a time. This results in a lockup while the
system waits indefinitely for the dead card to respond.
Hook up a TX lockup timer to detect this and reset the hardware.
