Feedback:
On pfSense 21.02/2.5, given that the igb driver is now replaced by the iflib em driver, the following no longer applies:

hw.igb.num_queues=1 # this is no longer used/needed
hw.igb.fc_setting=0 # this now needs to be set as a System Tunable like so: dev.igb.X.fc=0

Of note, hw.ix.flow_control=0 in loader.conf.local can still be used, though it's probably best to keep it as device specific so it can be included in config backups as System Tunables.

Regarding dev.igb.x.fc=0, this needs to be set as a System Tunable since it does not get applied after reboot if placed in the loader.conf.local file:

[21.05-RC][root@pfSense.home.arpa]/root: cat /boot/loader.conf.local
dev.igb.0.fc=0
dev.ix.0.fc=0
[21.05-RC][root@pfSense.home.arpa]/root: sysctl -a | grep dev.igb.0.fc
dev.igb.0.fc_low_water: 32752
dev.igb.0.fc_high_water: 32768
dev.igb.0.fc: 3
[21.05-RC][root@pfSense.home.arpa]/root: sysctl -a | grep dev.ix.0.fc
dev.ix.0.fc: 0

When used as a System Tunable and after reboot:

sysctl -a | grep dev.igb.0.fc
dev.igb.0.fc: 0

Note that his has been the case since 21.02/2.5.0.
