Subject: [PATCH] veth: take into account peer device for
NETDEV_XDP_ACT_NDO_XMIT xdp_features flag
For veth pairs, NETDEV_XDP_ACT_NDO_XMIT is supported by the current
device if the peer one is running a XDP program or if it has GRO enabled.
Fix the xdp_features flags reporting considering peer device and not
current one for NETDEV_XDP_ACT_NDO_XMIT.
Fixes: fccca038f300 ("veth: take into account device reconfiguration for xdp_features flag")
