Turn on adaptive MPSAFE for network threads, MPSAFE for IP and ARP

[Matthew Dillon]

:Hi all,
:
:I plan to set following tunables by default:
:net.netisr.mpsafe_thread="1"
:net.inet.udp.mpsafe_thread="1"
:net.inet.tcp.mpsafe_thread="1"
:net.link.ether.inet.arp_mpsafe="1"
:net.inet.ip.mpsafe="1"
:
:The first three enables adaptive MPSAFE for network threads.
:The last two enable IP and ARP MPSAFE.
:
:This gives us BGL free ip forwarding path and BGL free bridge
:forwarding path.  pf is still under BGL though.
:
:If no objection comes, this will happen within two days.

:Best Regards,

    Excellent!  This is the right time to do it.

    How does your network interface MPSAFE work tie into Aggelos's 
    sockbuf MPSAFE work?
