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.

should we check FEC_QUIRK_SWAP_FRAME here? something like:

	if (!(fep->quirks & FEC_QUIRK_SWAP_FRAME)
		ndev->xdp_features = NETDEV_XDP_ACT_BASIC |
				     NETDEV_XDP_ACT_REDIRECT |
				     NETDEV_XDP_ACT_NDO_XMIT;

Lorenzo
