There are known problems with laggproto lacp and if_bxe(4) due to
full-duplex detection I guess.
Workarround seems to be putting if_bxe(4) into promisc mode.

See https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=213606

Especially comment #8 and #13!

Mabye you can add your report to that bug, to raise it's priority.

Using if_lagg(4) with laggproto lacp and if_igb(4) doesn't show any
problems here on 11(-stable).
I also think there were LACPDU changes forcing the switch to be set to
active mode, but a very quick look didn't reveal a matching commit, so
maybe I'm wrong. Anyway, in your case it seems if_bxe(4) is the root
cause, not a configuration mismatch.
