ipfilter missing in most GENERIC kernels

["Frank Wille" <frank%phoenix.owl.de@localhost>]

Hi,

I'm using ipfilter since decades on my servers and was surprised that
the ipfilter pseudo-device was not included in the NetBSD-11 kernel
for sparc64.

I checked the source and realised that ipfilter is only enabled in
generic kernels for amd64 and i386. Why?

I didn't read any announcement that it is obsolete and replaced by
NPF or similar.
