Just had to spend some time figuring out why a bnx2 card connected to
a switch monitor port didn't see any vlan tags (when in our scenario the
tags are pretty vital). Found the following explanation:
[BNX2]: Fix VLAN on ASF
Always set up the device to strip incoming VLAN tags when ASF is
enabled. ASF firmware will not parse packets correctly if VLAN tags
are not stripped
My fix:
#ifdef I_DONT_KNOW_WHAT_ASF_IS_AND_DONT_REALLY_CARE_EITHER
if (REG_RD_IND(bp, bp->shmem_base + BNX2_PORT_FEATURE) &
BNX2_PORT_FEATURE_ASF_ENABLED)
bp->flags |= ASF_ENABLE_FLAG;
#endif
Any hope of getting this as a ethtool tunable or something similar?
There didn't seem to be a BIOS option for this (Dell PE2900), at least.

I'll have someone send you a utility to disable the ASF firmware.
