Subject: [net-next PATCH 6/6] fbnic: Add support for setting/getting pause
 configuration

From: Alexander Duyck <alexanderduyck@...com>

Phylink already handles most of the pieces necessary for configuring
autonegotation. With that being the case we can add support for
getting/setting pause now by just passing through the ethtool call to the
phylink code.
