Subject: Include the Routing Table ID in "struct rtentry" and reorder the fields
X-Git-Url: http://artulab.com/gitweb/?a=commitdiff_plain;h=fa6c7e6bbd4028141ead8f8882462f15b04efca8;p=openbsd

Include the Routing Table ID in "struct rtentry" and reorder the fields
such that there's no size change on, at least, amd64.

This will allow us to simplify some APIs and deprecate the remaining
flavors of "struct route".
