This protocol implements IPX/SPX over Ethernet_II frame type 0x8137.
|
|
Please note: the SPX implementation may require further work and testing
|
|
to insure proper operation.

(1) netipx default socket buffer sizes are very small by contemporary
|
|
standards, and should be increased following testing and measurement.
|
|
|
|
(2) SPX will free the PCB and socket buffer memory on close(), which means
|
|
close() in effects terminates the transfer of any outstanding buffered
|
|
but unsent data. As with TCP, it should instead grab its own
|
|
reference to the socket so that it is not released, as hold onto it
|
|
until the data transfer is complete.
|
|
|
|
(3) Raw socket capture of IPX output intercepts packets in the SPX output
|
|
routine in order to feed them back into the raw socket. This results
|
|
in recursion into the socket code in the transmit path; instead,
|
|
captured packets should be fed into a netisr that reinjects them into
|
|
raw sockets from a new (asynchronous) context.
|
|
|
|
(4) IPX over IP encapsulation needs work to make it properly MPSAFE.
