Merge branch 'qed-sriov-legacy'
Yuval Mintz says:
====================
qed*: IOV patch series
Recent FW [8.10.10.0] enabled us to support sriov interaction
with legacy VF/PF. This patch series adds the necessary driver changes
to utilize this additional compatibility.
In addition, utilize the new FW ability to prevent pause floods by VFs,
and fix a bug that is [mostly] exposed by the added legacy support.
====================
