Patrick Porlan bb0e3e0a58 PPP: Optimize write buffer management 
Extend the write buffer handling in gathdlc.c to minimize stalling and
process switching during large PPP transfers. The single write buffer
is replaced by a queue of buffers, allowing for much larger emission
windows without hugely impacting memory consumption. This reduces the
time required to send 50 MB between a couple of local PPP interfaces on
my laptop from ~53s to ~3s.

Denis Kenzior 0dc8e5e588 gathdlc: Try to detect no carrier conditions 
Sometimes we receive the no carrier embedded in a stream following the
PPP packets.  This might be due to write scheduling on the remote side
or read scheduling locally.  Try not to consume the no carrier condition
and assume the previous hdlc frames will result in closing of the ppp
stack.

Denis Kenzior 09ca5aaef0 gathdlc: Unregister read / write handlers 
When GAtHDLC is being unregistered make sure to unregister read / write
handlers so as not to crash.

Denis Kenzior 1cbe91090d gathdlc: drain the last hdlc frame processed 
If we're being destroyed, we should drain the last HDLC frame
