This looks good, but raises another issue: what about users who want
to use VLANs even though their hardware driver doesn't advertise the
ETHERCAP_VLAN_MTU capability (either because the hardware really
doesn't support it or because the driver hasn't been written to deal
with it)?  They might be willing to live with all the consequences of
a 1496 byte MTU.
