    ====================
    veth: fix peer NETDEV_XDP_ACT_NDO_XMIT after GRO is toggled while down

    Toggling GRO on a veth device while it is down leaves its peer's
    NETDEV_XDP_ACT_NDO_XMIT flag stale once the device comes up. XDP
    redirects into the peer are then rejected with -EOPNOTSUPP, or, if GRO
    was turned off, accepted and then dropped with -ENXIO. Patch 1 refreshes
    the peer's flags in veth_open().

    Patch 2 extends veth.sh to check the peer's flag after GRO is toggled
    while the device is down, in both directions.
