net: bandaid for plugging a fw_com leak in fwip_detach()
Adding a temporary workaround for plugging a fw_com upon if_fwip unloading.
Steps to reproduce(needs two hosts connected with firewire):
while true; do
ifconfig fwip0 10.0.0.5 up
fwcontrol -r
ping -c 10.0.0.3
kldunload if_fwip
done
There's a chance that the unloading of if_fwip.ko triggers following warning:
Warning: memory type fw_com leaked memory on destroy (1 allocations, 64 bytes leaked).
