if_igb(4) describe some hw.igb tunables (rxd, txd, enable_aim, num_queues). I guess these were gone after iflib conversion.
Another side effect, I am not able to control the LEDs via led(4).
Tested on 12.1-RELEASE, device river i211.
Reference: base r223676, base r228788.
Additional references: review D8299
Please see https://www.freebsd.org/cgi/man.cgi?query=iflib&sektion=4&manpath=freebsd-release-ports for a list of iflib sysctl variables.

Does it mean that the section "LOADER TUNABLES" from if_igb(4) manual should be removed?
(In reply to Jose Luis Duran from comment #3)
yes, can you submit a patch?

em.4: Remove non-applicable sections
Update manual to reflect current state.

Wait... I think I have to create a separate igb.4/if_igb.4 man page (revert base r350075), because if_em do have these tunables.

Remove LED-related sections
Sorry, I was reading the on-line version of the man page and got confused.
