svn commit: r230950 - projects/multi-fibv6/head/sys/netinet

[Bjoern A. Zeeb]

Author: bz

New Revision: 230950
URL: http://svn.freebsd.org/changeset/base/230950

Log:
  Document the fact that multi-FIB support for SCTP had been backed out
  in r179783 as (ab)using the concept of VRFs for this had not worked.
  At this point SCTP in FreeBSD does not support multi-FIB, neither for
  IPv4 nor for IPv6.
