So it is possible in principle that the same issue aff= ect also ixgbe(4). However, the NIC may be just different, not needing an explicit reset of the VME bit at interface initialization time. If anyone has some ixgbe(4) card = and is willing to test, they could try to play with VLANs, toggling the vlanhwt= ag ifconfig features on and off to check that things keep working. --=20 You are receiving this mail because: You are on the CC list for the bug.=
