OK; after:

Script started on Tue Nov  3 08:22:37 2015
g1-252(10.2-S)[1] (cd /S4/usr/src/ && svn diff -c 290334 >/tmp/r290334)^M
g1-252(10.2-S)[2] (cd /S4/usr/src/ && svn patch --reverse-diff /tmp/r290334)^M
U         sys/netpfil/ipfw/ip_fw_sockopt.c
U         sys/netpfil/ipfw/ip_fw_table.c
g1-252(10.2-S)[3] exit

followed by a "make buildkernel", I now have:

FreeBSD localhost 11.0-CURRENT FreeBSD 11.0-CURRENT #232  r290334M/290334:1100086: Tue Nov  3 08:27:20 PST 2015     root at localhost:/common/S4/obj/usr/src/sys/CANARY  amd64

and

localhost(11.0-C)[3] ifconfig wlan0 
wlan0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
        ether 00:24:d6:7a:03:ce
        inet 198.135.49.33 netmask 0xfffffc00 broadcast 198.135.51.255 
...

as I type, and IPFW is isn use


at a *guess*, we'll need a bit more effort to keep "found" and
"ci->object_opcodes" in sync, at least by the time the KASSERT on
src/sys/netpfil/ipfw/ip_fw_table.c:3395 looks at the values.

Thanks!

Peace,
