In drivers/net/bnx2.c:1285: it reads in function bnx2_setup_remote_phy():
if (pause_adv & (ADVERTISE_1000XPSE_ASYM | ADVERTISE_1000XPSE_ASYM))
Note that the two are the same and this is therefore equivalent to
if (pause_adv & ADVERTISE_1000XPSE_ASYM)
This appears to be incorrect, was maybe '| ADVERTISE_1000XPAUSE' intended?

Thanks for catching this. The patch below will fix it.
[BNX2]: Fix ASYM PAUSE advertisement for remote PHY.
We were checking for the ASYM_PAUSE bit for 1000Base-X twice instead
checking for both the 1000Base-X bit and the 10/100/1000Base-T bit.
The purpose of the logic is to tell the firmware that ASYM_PAUSE is
set on either the Serdes or Copper interface.
