Author: melifaro Date: Sat Apr 11 07:37:08 2020 New Revision: 359797 URL: https://svnweb.freebsd.org/changeset/base/359797
Log: Remove per-AF radix_mpath initializtion functions. Split their functionality by moving random seed allocation to SYSINIT and calling (new) generic multipath function from standard IPv4/IPv5 RIB init handlers.
