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.

3f2e8ebcdf PPP, MPPE, merged mppe_comp_init() and mppe_decomp_init() into mppe_init()
Removing a bit of redundancy and previous artefact of a generic kernel
interface. Exporting mppe_init() instead of mppe_comp_init() plus
mppe_decomp_init().

879c94b01e PPP, MPPE, removed mppe_alloc() and mppe_free()
We are going to use statically allocated struct ppp_mppe_state through PPP PCB,
removed now useless mppe_alloc() and mppe_free().

Merged mppe_alloc() key copy to mppe_init().

da40445d75 PPP, MPPE, changed API to use struct ppp_mppe_state* instead of void*
Now that struct ppp_mppe_state is exported, change MPPE API to use
struct ppp_mppe_state* instead of void*, we don't need that to be generic.

6235e1ae57 PPP, MPPE, moved struct ppp_mppe_state from mppe.c to mppe.h
In order to be able to use struct ppp_mppe_state statically allocated,
export struct ppp_mppe_state.

3618432107 PPP, MPPE, reworked mppe_rekey()
Moved sha1_context from struct ppp_mppe_state to stack, we don't need it past
mppe_rekey(). Moved shared MEMCPY() outside initial_key if block.

f1cba8a0ea PPP, MPPE, merged get_new_key_from_sha() to mppe_rekey()

caf9fc5687 PPP, MPPE, adapt compressor to use pbuf
mppe_compress() now takes a pointer to a pbuf pointer and re-use the
passed buffer for MPPE "compression".

dc93c2afec PPP, MPPE, removed address, control and protocol from compressor input
Our PPP stack deals with packet without address and control byte nor 2-byte
protocol field, improved mppe_compress() so we don't have to worry about
them.

them.

ab1606a0f6 PPP, MPPE, adapt decompressor to use pbuf
mppe_decompress() now takes a pointer to a pbuf pointer and re-use the
passed buffer for MPPE "decompression". Removed sub protocol handling
which can be shared among all decompressors in ppp.c

4d6d65ee33 PPP, MPPE, fixed SHA1 padding
SHA1 padding is 40 byte, not 256 byte. Rekeying is done for each
packet in stateless mode, ensure speedness using static table for padding.

57e3e7f150 PPP, MPPE, improved SHA1 padding
Don't allocate 512 bytes of RAM for padding. Reduce overall padding
size to 64, therefore using stack instead of RAM or ROM.

c759639603 PPP, MPPE, removed "compression" stats
We don't need "compression" stats on a encryption protocols, as commented
"Since every frame grows by MPPE_OVHD + 2 bytes, this is always going
to look bad ... and the longer the link is up the worse it will get."

is only relevant for the Linux kernel.

05eda236cc PPP, MPPE, import unmodified Linux MPPE encoder/decoder
This file, which is an unmodified copy of Linux MPPE encoder/decoder, is
licensed under a dual License BSD/GPL model. It was previously in the
pppd source tree and it was removed because this is merged into the Linux
kernel.
