Module Name:    src
Committed By:   ozaki-r
Date:           Fri May 19 08:53:51 UTC 2017

        src/sys/netinet: ip_carp.c

Log Message:
Allow CARP to call the link_state_change handler immediately

If the handler is delayed because of the indirection call via softint,
some operations are executed in reverse and may cause unexpected
behaviors. For example, due to the issue a GARP packet wasn't sent on
a transition from the BACKUP state to the MASTER state; this happened
because IN_IFF_DETACHED flag wasn't cleared on arpannounce, which
had been cleared in the link_state_change handler.
