Subject: Add minimal support for flowspec in the table-mp MRT format.
X-Git-Url: http://artulab.com/gitweb/?a=commitdiff_plain;h=211fe81c234be826d24047e5d0f0a70dae72b045;p=openbsd

Add minimal support for flowspec in the table-mp MRT format.
In general people should use table-v2 which handles flowspec just fine.
OK tb@
