[ax25-layer2] "First Code"

[Steve Sampson]

Just some minor style comments:

Those whitespace expansions of function calls to make them look like
structured code really make me dizzy:

erc = bind
(
    s,
    (struct sockaddr *)&lmBindingAddress,
    sizeof( struct sockaddr_un )
);

I don't think calloc is very expensive, and initialization is always good:

calloc( 1, sizeof( AX25PortProxy ) )

I don't see any free()'s, but it's something to think about for the shutdown
code as it develops.

This, after just one cup of coffee.  But hey!  I like the socket interface, and
while kernel space sounds groovy, I think even Linus has seen the error of
his ways.  Tanenbaum's Minix became this great big NOS looking monolith.

    "Can the LM be implemented in kernel-space in some way?"

    "No."  :-)

Cheers,
Steve
