Subject: [PATCH net 0/2] Two phylink pause fixes

While testing, I discovered two issues with ethtool -A with phylink.
First, if there is a PHY bound to the network device, we hit a
deadlock when phylib tries to notify us of the link changing as a
result of triggering a renegotiation.

Second, when we are manually forcing the pause settings, and there
is no renegotiation triggered, we do not update the MAC via the new
mac_link_up approach.

These two patches solve both problems, and will need to be backported
to v5.7; they do not apply cleanly there due to the introduction of
PCS in the v5.8 merge window.
