Can't add gif interface to bridge for transparent  ipsec.
In versions NetBSD 3.x; 4.x_BETAx and NetBSD 4.99.3 gif interfaces work normaly and bridge can add gif0.
>How-To-Repeat:
ifconfig gif0 create
ifconfig gif0 tunnel 10.10.10.10 10.20.30.40
ifconfig gif0 mtu 1500 up
ifconfig bridge0 create
brconfig bridge0 add ex0 add gif0
... at this moment brconfig output error:: Invalid argument: gif0

>Fix:
I diff the brconfig in sbin/brconfig.c with work correctly version of sources in NetBSD 4.0_BETA2 at 2007-04-24 in my workstation, but user land  tool has no changes.

After that look in sys/net and find tiny changes in if_bridgevar.h. changes only type of variable ifbicu_buf to void*. Nothing scary and serious.
In if_bridge.c is same situation correct type-casts for new type declared in header.
At first view I can't see reason for this bug. ??????!!!!

Dummy speed-fix at this moment, may be this interface bridge driver use other version from netbsd-4 branch

 etherip support has been split from gif(4) into etherip(4) a while ago.
 So replace gif here with etherip (and make sure you have "pseudo-device
 etherip" in your kernel configuration).
