--- Comment #2 from Eric Joyner <erj at freebsd.org> ---
Looking at iflib.c, it appears iflib_init_locked() expects the driver-specific
init function to not set any driver flags, but ixv_if_init() in if_ixv.c (the
function called as IFDI_INIT() in iflib_init_locked()) modifies those flags,
which I think causes the MPASS() to fail.

So, I think this last bit in ixv_if_init() needs to be removed:

        /* Now inform the stack we're ready */
        ifp->if_drv_flags |= IFF_DRV_RUNNING;
        ifp->if_drv_flags &= ~IFF_DRV_OACTIVE;
