I mentioned December 29, sorry if that wasn't explicit enough, I didn't
have the svn revision close to hand.
Is r226260 the MFC that you're referring to? The log says, "Skip
TCP_SIGNATURE calculation for INP_TIMEWAIT case." If so, that happened
in October so we're well past that in our version of -stable.
I'll be working on the various suggestions (thanks everyone for them,
most helpful!) and report back on what works.
Doug
