CVS commit: src/sys/net

[David Young <dyoung%netbsd.org@localhost>]

Module Name:    src
Committed By:   dyoung

Modified Files:
        src/sys/net: if.c

Log Message:
The departure of IPv6 interfaces does not agree with pf.  The pfil
hooks that signal the interface's departure run before IPv6 sends
messages to indicate that it is leaving its multicast groups; when
pf filters the departure messages, it does not recognize the output
interface, so it complains at the departure of gre65, for example:

pf_test6: kif == NULL, if_xname gre65

I have changed if_detach() so that it calls pr_usrreq(PRU_PURGEIF)
before pfil_run_hooks(PFIL_IFNET_DETACH), instead of the other way
around.  That quiets the pf_test6: messages.
