svn commit: r195862 - head/sys/netinet/ipfw

[Tor Egge]

This commit causes my laptop to hang during boot.

ipfw and ipfw_nat are both compiled into the kernel:

options         IPFIREWALL
options         IPFIREWALL_VERBOSE
options         IPFIREWALL_VERBOSE_LIMIT=100
options         IPFIREWALL_FORWARD
options         IPFIREWALL_NAT
options         IPDIVERT

The kernel hangs during

    IPFW_WLOCK(&V_layer3_chain);

at the start of ipfw_nat_init.  The lock is not yet initialized at this time
(SI_SUB_PROTO_IFATTACHDOMAIN, SI_ORDER_ANY), since the commit moved the
initialization of the lock from
(SI_SUB_PROTO_IFATTACHDOMAIN, SI_ORDER_ANY - 256) (cf. ipfw_modevent() calling
ipfw_init()) to (SI_SUB_KTHREAD_INIT, SI_ORDER_ANY) (cf. vnet_ipfw_init()).
