netdemo: TCP locks up after echoing 11K

 Thank you for all the suggestions, but it turns out I was stupider than
that: when transmitting packets, I was putting 1 byte too many into the
MAC hardware...  Therefore, all the ACKs were coming through but the
actual data was not.  And this occurs only after a while due to MSS
discovery.

 To debug this error, I added a SOCK_RAW socket test to the netdemo. 
Would it be useful to contribute that?  Patch is in attachment.

 Regards,
 Arnout
