[PATCH 4.14 474/496] dpaa_eth: fix pause capability advertisement logic

[Greg Kroah-Hartman]

4.14-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Jake Moroni <mail@xxxxxxxxxxxxxx>

[ Upstream commit 3021efb440d02bf5b952b6d151c7ffee9bdd49fe ]

The ADVERTISED_Asym_Pause bit was being improperly set when both
rx and tx pause were enabled. When rx and tx are both enabled, only
the ADVERTISED_Pause bit is supposed to be set.
