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.

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.

5989c1883e PPP, removed useless padding in bitfields

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.

We need to know which methods were chosen when CCP is up, this used to be done

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