Aweee.. So you and the chair both fell over huh?? :)
Hey, I'm no professional programer, I'm just a dabbler..

Was hoping for a suggesting here, Got any??
Linux sockaddr_ipx has it as:
unsigned char sipx_node[IPX_NODE_LEN];

Something like so:
union ipx_net {
u_char c_net[4];
u_short s_net[2];
u_long l_net;
};
#define sipx_network sipx_addr.x_net.l_net
Looks good, Is it technically good???
What will this do to any of the current IPX code!
No, I don't have the 'Big Picture' of the IPX code yet, I'm still
figuring it out.
It would help tremendously<sp?> If I could put IPXrouted to use
somehow! So I can see it in action.
I'm sure your goals are the same as mine, I don't want to do
anything to the kernel thats not good for FreeBSD in the whole!
Thanks for your time.
-Enjoy
Gary
