I have just discovered during some validation testing on the em driver,

at the same time as VLAN_HWTAGGING and/or VLAN_HWFILTER that its broken.
Looking at the vlan source its not obvious why this would be the case, but
netperf just fails completely.
I can turn TAGGING off and I can get TSO, or turn off TSO and get
TAGGING/FILTERING, but not
both :(
My tester only has 8.2 to try this on, not sure if its a bug or a design
limitation, can someone
enlighten me? At the moment I'm thinking of just turning HWTSO off by
default?
Maybe the HW or drive chokes on the overall ethernet frame being longer
than 64K due to the VLAN header even though the IP packet part stays
within the limits?
