[PATCH 5.4 27/85] nfp: update ethtool reporting of pauseframe control

From: Fei Qin <fei.qin@corigine.com>

[ Upstream commit 9fdc5d85a8fe684cdf24dc31c6bc4a727decfe87 ]

Pauseframe control is set to symmetric mode by default on the NFP.
Pause frames can not be configured through ethtool now, but ethtool can
report the supported mode.

Fixes: 265aeb511bd5 ("nfp: add support for .get_link_ksettings()")
