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

   34 (1) netipx default socket buffer sizes are very small by contemporary
   35     standards, and should be increased following testing and measurement.
   36 
   37 (2) SPX will free the PCB and socket buffer memory on close(), which means
   38     close() in effects terminates the transfer of any outstanding buffered
   39     but unsent data.  As with TCP, it should instead grab its own
   40     reference to the socket so that it is not released, as hold onto it
   41     until the data transfer is complete.
   42 
   43 (3) Raw socket capture of IPX output intercepts packets in the SPX output
   44     routine in order to feed them back into the raw socket.  This results
   45     in recursion into the socket code in the transmit path; instead,
   46     captured packets should be fed into a netisr that reinjects them into
   47     raw sockets from a new (asynchronous) context.
   48 
   49 (4) IPX over IP encapsulation needs work to make it properly MPSAFE.
