Yes, it can:
# vconfig add eth0 12
# ifconfig eth0.12 192.168.1.1 255.255.255.0
And I keep asking: do you want to tag all traffic on eth0 using the
same VLAN ID? Do you connect eth0 to a real switch? If you answer yes
to both questions, tag the Ethernet frames at the switch.
PD: AFAIK, RHEL tags Ethernet traffic using subinterfaces, like eth0.1
or eth0.12 so, yes, AFAIK, RHEL also uses subinterfaces since this is
a feature of the kernel itself and not of the distribution.
