Subject: [PATCH net 0/2][pull request] ice: xsk: ZC changes

Maciej Fijalkowski says:

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.

The following are changes since commit 797666cd5af041ffb66642fff62f7389f08566a2:
  net: usb: qmi_wwan: Add new usb-id for Dell branded EM7455
and are available in the git repository at:
  git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/net-queue 100GbE

  ice: xsk: change batched Tx descriptor cleaning
  ice: xsk: drop power of 2 ring size restriction for AF_XDP
