--- Comment #6 from Kevin Bowling <kbowling@freebsd.org> ---
This is fixed in igbv(4).

A PF driver, for instance Linux igb_ping_all_vfs(), sends a control message=
 as
far back as introduction, so the issue was FreeBSD VF losing the message
because the driver treated ICR like a PF.

Your fix was legitimate, but I don't think it's necessary with a working VF
driver.
