Subject: [PATCH net-next v2 4/4] qed: add support for link pause configuration.

From: Sudarsana Reddy Kalluru <sudarsana.kalluru@...gic.com>

The APIs for making this sort of configuration [e.g., via ethtool] are
already present in qede, but the current configuration flow in qed doesn't
respect it.
