Freescale FEC i.MX28 VLAN support?

Hi,

is there any particular reason why the FEC_QUIRK_HAS_VLAN
is only set for imx6q-fec ?

According to the reference manual the VLAN support is also
present in i.MX28 and the DMA descriptors look the same
in this regard, but this is from eyeballing only, I did not
try to play with it yet.

The reason I am asking is that I am using a switch that can
tag the frames according to the port a packet is received
from/sent to and I would like to use that feature.

Please Cc: me when replying.

Thanks
