I just upgraded to 2.1 and a problem I was seeing with PPP under 2.0
(with all the patches) seems to be worse under the virgin 2.1 install.
When my modem (both a 14.4 USR and a 28.8 Moto power) connects and
enters the phase where it's waiting for BOS, it always times out.
I did an 'ifconfig ppp0 debug' to see what was happening and it looks like
my ISP's PPP is sending an unknown parameter on the Configure-Request
command. I also see errors from the ppp driver whining about 
"CORRUPT PACKET". There are usually quite a lot of these, and eventually
my end gives up.

Under 2.0.1 with the patches, I would see this occasionally. For reasons
unbeknownst to me, starting ppp with the -x option would usually make
the link work. However, after doing the upgrade I can no longer connect
at all.

Anyone else see this problem? Any suggestions as to fixes I could make
to either ppp or the driver to make it happy?

Thanks,
Peter
