It is a major interoperability issue.  With the default sysctl settings,
we can not establish connection to BSD systems.  Yes, there is a workaround
of turning on the 2 required sysctl settings, but that is totally suboptimal.

I've thought about this fix for a while, and in my opinion, the interoperability
problem is large enough to warrant the fix at this time and the backport to
table.

Of course you are free to not include this in net-2.6, but I hope you will.

Thanks
