list_empty() right before this code, and it is protected by fq->lock.
Nevermind then.

Anyway, if the patch seems worthless just ignore it. I'll leave it in my tree
since it should be harmless and will let you know if I ever hit it.
If someone else hits a similar crash, hopefully they can report it.

This is similar to ETHTOOL_GSTATS, but it allows you to specify
a 'level'. This level can be used by the driver to de

Any chance you can recreate the issue with standard pktgen
a snapshot of what is using CPU time
on the system. It will probably give you a pretty good idea where the
code is that is eating up all your CPU time.

sending from something external on the system or are you actually

I am getting warnings about sign missmatch.
Maybe make SPEED_UNKNOWN be ((__u32)(0x)) ?
from ethtool.h:
#define SPEED_UNKNOWN -1
static inline int ethtool_validate_speed(__u32 speed)
{
return speed <= INT_MAX || speed == SPEED_UNKNOWN;
}

S crash when using QCA 9984 NIC on x86-64 system
without vt-d enabled.
Also tested on ea8500 with 9980, and x86-64 with 9980 and 9880.
All tests were with CT firmware.

This is probably not an NFS specific issue, though I guess possibly it is.
Forwarding to netdev in case someone wants to take a look at it.

for fixing this!
It would not be fun to have to revert to the old way of hashing
stations in mac80211...
I'll be happy to test the patches when you have them ready.

what is that '+ 64 +' for in the size calculation?
Looks a lot like some fudge factor from long ago?

(We see about 800Mbps UDP download, but only 500Mbps TCP, even when
using 100 concurrent TCP streams.)
Is there some way to tune the TCP stack to better handle reordered frames?

How do you feel about a new socket-option to allow a socket to
