[Intel-wired-lan] ixgbe - only presenting one out of four interfaces on 5.9

[Ian Kumlien]

Hi,

I was really surprised when i rebooted my firewall and there was
network issues, I was even more surprised when
only one of the four ports of my ixbe (x553) nic was available when booted.

You can actually see it dmesg... And i tried some basic looking at
changes to see if it was obvious.... but..

anyway, on v5.8.14:
dmesg |grep ixgbe
