As a general hint to you and everyone else submitting patches: if you
can break them in parts, do so. If you can break the parts, break them
The patches may depend on each other, no problem if #2 doesn't work if
#1 is missing; however each patch should leave the tree in a buildable,
working state (exceptions to this are very rare).
The point of this is that e.g. the first half of you patch can be merged
very easily since the consequences are foreseeable. The second half -
not that much, it _might_ break some compatibility.
In your case, Mike: make 2 or 3 patches:
#1: the new sockunion function
#2: ospf6_set_reuseaddr removal (this could be merged into patch #1,
both are very small overseeable)
#3: insertion of call to sockopt_mcast_ttl
This way even if there's some more thinking about patch #3, #1 and #2
can go in immediately. Also, if a different approach about #3 turns out
to be better (e.g. adding an "ipv6 ospf ttl X" command or something), we
can easily change that.
I understand this might cause a little more work for you on submitting
the patch; however, if everyone does this, it takes a LOT of work off
the maintainer's shoulders :)
