History

Robert Watson bc725eafc7 Chance protocol switch method pru_detach() so that it returns void rather than an error. Detaches do not "fail", they other occur or the protocol flags SS_PROTOREF to take ownership of the socket. soclose() no longer looks at so_pcb to see if it's NULL, relying entirely on the protocol to decide whether it's time to free the socket or not using SS_PROTOREF. so_pcb is now entirely owned and managed by the protocol code. Likewise, no longer test so_pcb in other socket functions, such as soreceive(), which have no business digging into protocol internals. Protocol detach routines no longer try to free the socket on detach, this is performed in the socket code if the protocol permits it. In rts_detach(), no longer test for rp != NULL in detach, and likewise in other protocols that don't permit a NULL so_pcb, reduce the incidence of testing for it during detach. netinet and netinet6 are not fully updated to this change, which will be in an upcoming commit. In their current state they may leak memory or panic. MFC after: 3 months		2006-04-01 15:42:02 +00:00

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.

--- TODO ---

(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.
