[PATCH v2 intel-net 0/2] ice: xsk: ZC changes

[Maciej Fijalkowski <maciej.fijalkowski@intel.com>]

Hi,

this set consists of two fixes to issues that were either pointed out on
indirectly (John was reviewing AF_XDP selftests that were testing ice's
ZC support) mailing list or were directly reported by customers.

First patch allows user space to see done descriptor in CQ even after a
single frame being transmitted and second patch removes the need for
having HW rings sized to power of 2 number of descriptors when used
against AF_XDP.

I also forgot to mention that due to the current Tx cleaning algorithm,
4k HW ring was broken and these two patches bring it back to life, so we
kill two birds with one stone.

v2:
- remove doubled fixes tag from patch 1
- add Alasdair to CC as he reported need for bigger rings used with
  AF_XDP ZC

Thanks!
Maciej
