Subject: [PATCH 0/3 net-2.6] bnx2x: Bug fixes in statistics handling

Dave, pls., consider applying the following patches to the net-2.6 tree.
They include 2 bugs fixes in the statistics handling flow:

1) Protect the statistics state machine state update with a spinlock.
Otherwise there was a race condition that would cause the statistics
stay enabled despite they were disabled in the LINK_DOWN event handler.

2) Protect statistics ramrod sending code and a statistics counter
update with a spin lock. Otherwise there was a race condition that would
allow sending a statistics ramrods with the same sequence number or with
sequence numbers not in a natural order, which would cause a FW assert.

Thanks,
vlad
