Description Andrew Cagney 2022-05-07 13:26:14 UTC 
(yea, admittedly, there's no real standard)

It seems that when building a message to send to PF_ROUTE requires some magical alignment.

FreeBSD defines, but doesn't document, SO_SIZE()
NetBSD defines, but doesn't document, RT_ADVANCE() and RT_ROUNDUP()
OpenBSD hides definitions for ADVANCE() and ROUNDUP() in route.c

Can I suggest adding/documenting the RT_* macros; mainly because everything else in net/route.h starts with the RT* prefix.
