- pppd compatibility
- for that matter, reimplement bpolicy
- L2TP
	- improve multilink fragmentation
	- changing multihop tunnel secrets does not work if peer already 
	  exists from failed connection attempts
- make isdn channels ttys with HDLC line discipline???
- scb: cards need to be reset to HDLC framing when in old PPP mode
- make install fails on src
- change PAP/CHAP/NONE auth flag to PAP_OKAY/CHAP_OKAY/NONE_OKAY.
- clean up EPD stuff
- limiting dialing channels w/min/max links must not dialout
- clean up make file process so everything builds correctly
- protocol negotiation needs clamps on the amount of traffic being sent (IPCP storm)

- Feature requests for bquery (or something similar):
	- connect time - done
	- last in & out packet times
	- MTU/MRU (if that's possible)

- make babylond can re-exec itself enabling bug fixes without any loss of 
  in-progress L2TP sessions. -- mostly done via dump-full-state and -S.
- replication
	- log i/o to aid in collecting debug traces
	- use i/o logging to replicate exact state for hot standby
	- add dfs support
- proxy authentication
	- PAP works!
	- implement/test CHAP
- proxy LCP
	- MRU renegotiation based on Radius
- l2tpctl monitor <user@domain> - watch incoming control traffic for a 
  particular user to aid in debugging
- BUG: l2tp packets coming in on stale sessions should cause a tunnel abort
- BUG: bvirt: ctrlfd_t / select interaction is failtown
- unimplemented: save/restore doesn't cope with virtual network namespaces
- add bvirt-down-{host,guest}
- BUG: fix bvirt del, currently doesn't do any real cleanup
- test radius acct remove while radius requests are in flight
- fully test ip pool contention and exhaustion
- TODO: finish Ascend Radius filters (wire up to iptables)
- kernel: babylon.c: make MLPPP zero copy for paged skbs on e1000e
- BUG: kernel: routing loop (del default gw, point gw to l2tp session)
- make ioctls 64/32 bit clean
- BUG: Call gets leaked on pppoe repeated dialouts with stale channels
- BUG: ctrl-c of l2tpctl start-session while remote end not up results in SEGV
- verify that late binding of UDP in l2tp_peer_t works for all cases
- PAP Proxy authenticate: verify that LCP and PAP are started correctly
- implement CHAP proxy authentication
- write man page for l2tpctl
- add statistics (nee l2tpctl stats)
- pass initial and final LCP packets on tunnel switching
- byte counters in bquery
- test suite for bpppoe and l2tp userland sessions
- test bpppoe relay and netns
- l2tp_session_t - remove multihop_clink?
- kernel/babylon.c - use_existing_call - missed hangups with PPPoE?
- bpppoe relay - timeout idle sessions
