Porting lagg(4) from FreeBSD

[s ymgch]

Hi tech-net@,

I am porting lagg(4) from FreeBSD for making the feature of link-aggregation
mp-safe and for improving functions.
I put the patch at following links, and I'd like your comment about it.

The patch is here:
http://netbsd.org/~yamaguchi/lagg.patch
and
https://github.com/s-ymgch228/netbsd-src_offficial/pull/1/files

Thanks,

Hi,

Yes, your guess is correct. And my main motivation is also
to make agr(4) mp-scalable.
I tried to change agr(4) before the porting, but I gave up
because agr(4) has some bugs and it is a complicated implementation.

In addition to this reason, lagg(4) supports methods to create
a Link-Aggregation-Group(LAG) named "failover" and "loadbalance" besides
"lacp" that agr(4) also supports. And I want to use them.

Hi, Yamaguchi-san!
Can you say anything about how it compares or relates to agr(4)?
(I haven't looked at lagg(4) at all yet, and I don't know much about
agr(4); this is not criticism of the work you did! Just curious how
it relates to the other thing we have with `link aggregation' in the
title. I'm guessing that agr(4) is not MP-scalable or something.)

We should remove agr eventually though..
