Hello, I'm experiencing an issue where pppd hangs up, but only when traffic is sent over the connection. The connection is stable if it is idle, but soon after any traffic is sent over the connection pppd hangs up. For example, 15-30 pings or a few lines into a telnet session kills the connection. I suspect this is the result of a lack of support for a Link Quality Report (which is Confreq'd by the target). As you can see in the debug about below if-down is started after the "rcvd [LCP ConfReq id=0xf0 <mru 400> <quality lqr 00 00 01 2c> <magic 0xc0a80ea5> <pcomp> <accomp>]". This ConfReq occured after 17 successful pings over the link, and the link went down after the ConfReq. Is this expected behaviour?
