From: Mateusz Palczewski <mateusz.palczewski@xxxxxxxxx> [ Upstream commit 4cdb9f80dcd46aab3c0020b4a6920c22735c5d6e ] During driver loading flow control settings were written to FW using a variable which was always zero, since it was being set only by ethtool. This behavior has been corrected and driver no longer overwrites the default FW/NVM settings.
