Commit 8c14586fc320 ("net: ipv6: Use passed in table for nexthop lookups") introduced a regression: insertion of an IPv6 route in a table not containing the appropriate connected route for the gateway but which contained a non-connected route (like a default gateway) fails while it was previously

[net PATCH] mlx4: fix XDP_TX is acting like XDP_PASS on TX ring full

The XDP_TX action can fail transmitting the frame in case the TX ring is full or port is down. In case of TX failure it should drop the frame, and not as now call 'break' which is the same as XDP_PASS. Fixes: 9ecc2d86171a ("net/mlx4_en: add xdp forwarding and data write support") Signed-off-by:
