I'm glad mouse-pppoe is helping someone!

They were for me, though I had to read pppd(8) carefully and make sure
I knew which options files were read when to create the right ones.

I'm not sure what you mean: no particularly good reason for advertising
an MSS less than 1500, or for making it that low, or for picking 1400,
or what?  An MSS less than 1500 is necessary on Ethernet hardware that
can't send and receive oversized packets.  If the hardware involved in
your case can, feel free to s/1400/1500/ in the code - but not all
hardware can.  It doesn't have to be as low as 1400, no; I picked that
because it meant I didn't have to figure out exactly how much overhead
there was.  As for why exactly 1400, only because it was a round number
that was large enough to not impair performance too much and small
enough to be definitely less than ETHERMTU after adding on PPPoE gunk.

As for the MSS clamp botch, well, that particular horse has been beaten
to death long since; I'm not going any closer to it than inheres in
calling it a "botch".  (On-list, at least.  If you're curious, I'll be
happy to rant at length off-list.)

Thrills.  Back when I used PPPoE, my username was, if I recall
correctly, b1widp03, apparently selected by a similarly brilliant
algorithm.
