78e1b9b7c1 PPP, don't store the name by which the peer authenticated itself to us if multilink support is disabled 
pcb->peer_authname is only used by multilink support (which we don't
support), don't store the useless peer authname.

fd53cad208 PPP, sifnpmode() is only useful if on demand is supported, build out if not 
We don't support PPP on demand, don't build sifnpmode() which is only
useful for on demand if on demand is not supported.

1b6d6d0dc0 PPP, removed unnecessary memset() 
Everything is cleared in ppp_clear(), we don't need to clear all
structures twice.

If there is enough space in front of the buffer, use it instead of
allocating a new pbuf.

900f3c9a09 PPP, MPPE, don't issue CCP reset request in stateless mode 
This is useless, flushed bit is always true in stateless mode, we
don't need to issue a CCP reset request in this case.

8fe2f747f4 PPP, MPPE, issue CCP reset request if synchronization is lost 
If MPPE synchronization is lost, it is advised to send a CCP reset
request in order to recover to a clean state.

adaeff5540 PPP, MPPE, discard late packet in stateless mode 
When PPP is used over a link which does not guarantee packet ordering,
we might get late MPPE packets. This is a problem because MPPE must be
kept synchronized and the current implementation does not drop them and
rekey 4095 times instead of 0, which is wrong.

In order to prevent rekeying about a whole count space times (~ 4095
times), drop packets which are not within the forward 4096/2 window and
increase sanity error counter.

d0f91c00cb PPP, MPPE, sanity error path rework 
We are going to need sanity error path a little further, rework to be
able to use the sanity error path anywhere in decompressor.

5e43e2d333 PPP, L2TP, minor fixes 
Check tot_len for ZLB instead of len, it might happens we are just
between 2 pbuf, although almost impossible.

Check buffer is at least 2 byte long before checking address & flags
header.

15cc47334e PPP, don't assert if we receive a too short packet in ppp_input(), just drop 
We might actually receive too short packets through PPPoE or PPPoL2TP,
don't assert on unusal packets, just drop them.

632de523de Fixed PBUF_LINK_ENCAPSULATION_HLEN support 
PBUF_LINK_ENCAPSULATION_HLEN support was introduced by 6ef7563f and
missed the fact that header size calculation/reservation using
computation like PBUF_LINK_HLEN + PBUF_IP_HLEN + ... are used all over
the source code. Hopefully fixed all of them.

b302cad46d PPP, VJ, CCP: rework to fix protocol order 
We need to do VJ compression before CCP/MPPE compression and VJ
decompression after CCP/MPPE decompression. This leads to a massive
rewrite of how we currently handled VJ only in the PPPoS lower protocol
handler.

Moved VJ structures from pppos to ppp_pcb because we need them back in
PPP core. This is a bit unfortunate because that's not necessary for
PPPoE or PPPoL2TP, but, hey!. Fixed CCP+MPPE+VJ order.

the callback it is calling.

ffb10e7aac PPP, CCP, added receive and transmit chosen protocols in ccp_flags_set() (renamed ccp_set()) 
We need to know which methods were chosen when CCP is up, this used to be done
using ccp_test() which we are in the process of removing.

Using non-existing method 0 instead of -1 in CCP for unset method, allowing
type change from s16_t to u8_t for method.

fc7e327d19 PPP, MSCHAP, CCP, MPPE: reworked key passing from CCP to MPPE 
Removed mutiple copies of keys by pre-setting MPPE keys during MSCHAP
negotiation.

Improved MPPE init so we don't need to pass a buffer formatted in a
special way to MPPE, this is necessary for pppd to talk to the kernel,
we don't need that here.

867d13b007 PPP, CCP, MPPE: calling mppe_init() in ccp.c instead of using ccp_test() 
We don't need this ccp_test() stuff which is used to test if kernel have
the ability to process MPPE packets. Reworked MPPE so we don't need it.

3862aad2f7 PPP, MSCHAP, reworked local functions and constants 
MSCHAP was written the old-way, with all functions declared non static in
header, independent of their local or global scope status. Same for local
constants. Reworked in a more mordern way.

ab46ac9bd8 PPP, CHAP, reworked to pass ppp_pcb pointer to CHAP childs (MD5, MSCHAP, MSCHAPv2) 
We are going to need ppp_pcb* in MSCHAP and MSCHAPv2 for MPPE for
int mppe_keys_set, u_char mppe_send_key and u_char mppe_recv_key
which are currently global variable which must be moved to ppp_pcb.

74054ea907 PPP, MPPE, struct ppp_mppe_state to typedef 
We usually handle "typedefed" struct in lwIP, and I agree this is a cleaner
approach. Replaced struct ppp_mppe_state to ppp_mppe_state.
