Hi,

it's been a while. Here's another revision of XDP_TX improvements for
ice. This time I decided to split the generic ring struct that was
serving both Tx and Rx sides onto separate entities. It is due to the
fact that this set introduces few Tx specific fields onto ring.

Also, when compared to v2, Xdp ring is propagated onto Rx ring.
Accessing vsi->xdp_rings array, especially in fallback path, is not
convenient.

This v4 fixes the compile issue reported by lkp.

Finally patch 5 introduces yet another cleaning logic, different from
v2. For more info please see commit messages.

Thanks!
Maciej
