Log Message:
Pull up following revision(s) (requested by jym in ticket #1609):
sys/arch/xen/xen/if_xennet_xenbus.c: revision 1.50
sys/arch/xen/xen/xennetback_xenbus.c: revision 1.43
Check that xvif(4) is not already connected before proceeding in the
XenbusStateConnected mode. Under rare occasions, the xenbus watcher
can fire multiple times, overwriting the I/O ring memory mappings with
invalid values. This will lead sooner or later to dom0 panic().
Will ask for pullup. FWIW, xbdback(4) is not affected.
Check status before proceeding further. Avoids spurious watch calls.
