Subject: [net-next 14/14] ice: Ignore EMODE when setting PHY config

From: Chinh T Cao <chinh.t.cao@...el.com>

When setting the PHY cfg (CQ cmd 0x0601), if the firmware responds
with an EMODE error, software will ignore the error as it simply
means that manageability (ex: BMC) is in control of the link and that
the new setting may not be applied.
