Ok, I guess that will fix the sniffing issues and any user-space
bridging type applications.
Currently, VLAN devices offer the ability to 'reorder' the header and
explicitly remove the VLAN
header. I assume we keep this feature and have the AF_PACKET logic
check the device
flags to see if it should insert the VLAN header for hw-accel vlans?
Either way, if we sniff the underlying device, we should always get the
VLAN header.
What about drivers and filtering VLANs? It seems there is still a
difference between software
vlans and hw-accel in this case.
Thanks,
Ben
