NetBSD/sys/dev/isa/isic_isa.c
pooka dae7af8b24 Ready the kernel side of i4b for primary rate interface support by 
removing assumptions that there are only two B channels and by
adding support for a varying number of channels.

Due to this, rename previously used isdn identified "bri" to "isdnif",
which better describes the current situation.
