mlx4: xdp_prog becomes inactive after ethtool '-L' or '-G'
After calling mlx4_en_try_alloc_resources (e.g. by changing the
number of rx-queues with ethtool -L), the existing xdp_prog becomes
inactive.
The bug is that the xdp_prog ptr has not been carried over from
the old rx-queues to the new rx-queues
