Subject: [PATCH V2 net-next] net: fec: turn on XDP features

From: Wei Fang <wei.fang@....com>

The XDP features are supported since the commit 66c0e13ad236
("drivers: net: turn on XDP features"). Currently, the fec
driver supports NETDEV_XDP_ACT_BASIC, NETDEV_XDP_ACT_REDIRECT
and NETDEV_XDP_ACT_NDO_XMIT. So turn on these XDP features
for fec driver.

Signed-off-by: Wei Fang <wei.fang@....com>

V2 change:
fec with FEC_QUIRK_SWAP_FRAME quirk does not support XDP, so
check this condition before turn on XDP features.
