Hi,
Thanks to introducing softint-based if_input,
we can simplify bridge(4).
- Remove spin mutexes
- They were needed because some code of bridge could run in
hardware interrupt context
- We now need only an adaptive mutex for each shared object
(a member list and a forwarding table)
- Remove pktqueue
- bridge_input is already in softint, using another softint
(for bridge_forward) is useless
- Packet distribution should be down at device drivers
As expected, forwarding performance improves slightly
because of stopping using the second softint.
Here is a patch:

Any comments or suggestions?
Thanks,
