protocols, and lacking any timeouts, but it basically works, doing four-way
handshakes in both directions and incoming Machine Peek operations.
Oh, and Econet is Acorn's ancient, proprietary 500kbit/s networking
technology.
based on the existing net/if_spppsubr.c stuff.
While there are completely userland (bpf based) implementations available,
those have a vastly larger per packet overhead thus causing major CPU
overhead and higher latency. On an i386 base router, running a 486DX at 50MHz
my line (768kBit/s downstream) was limited to something (varying) between 10
and 20 kByte/s effective download rate. With this implementation I get full
bandwidth (~85kByte/s).
This is client side only. Arguably the right way to add full PPPoE support
(including server side) would be a variation of the ppp line discipline and
appropriate modifications to pppd. I promise every help I can give to anyone
doing that - but I needed this realy fast. Besids, on low memory NAT boxes
with typically a single PPPoE connection, this implementation is more
lightweight than a pppd based one, which nicely fits my needs.
that reference them don't have to slurp in all of the BPF headers.
Define a new generic RAWAF type that is like DLT_RAW, but isn't specific
to IP (the macro takes an AF_* constant as an argument to generate the
actual type).
