Modified files:
sys/netinet ip_mroute.c
Log:
o move mutex init/destroy logic to the module load/unload hooks;
otherwise they are initialized twice when the code is statically
configured in the kernel because the module load method gets
invoked before the user application calls ip_mrouter_init
o add a mutex to synchronize the module init/done operations; this
sort of was done using the value of ip_mroute but X_ip_mrouter_done
sets it to NULL very early on which can lead to a race against
ip_mrouter_init--using the additional mutex means this is safe now
o don't call ip_mrouter_reset from ip_mrouter_init; this now happens
once at module load and X_ip_mrouter_done does the appropriate
cleanup work to insure the data structures are in a consistent
state so that a subsequent init operation inherits good state
