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

Imx28 also support the feature, you can enable it.
HW only support detect VLAN packet. The function with the config just using software to remove VLAN tag while receiving one packet.
Thanks,
