====================
Aquantia atlantic critical fixes 04/2018

Two regressions on latest 4.16 driver reported by users

Some of old FW (1.5.44) had a link management logic which prevents
driver to make clean reset. Driver of 4.16 has a full hardware reset
implemented and that broke the link and traffic on such a cards.

Second is oops on shutdown callback in case interface is already
closed or was never opened.
