This is an important kernel ipx patch for all known kernels.
In linux/net/ipx/af_ipx.c routine ipx_create one line is missing.
static int ipx_create(struct socket *sock, int protocol)
{
...
sk->rcvbuf=SK_RMEM_MAX;
sk->sndbuf=SK_WMEM_MAX;
sk->allocation=GFP_KERNEL;
.......^^^^^^^^^^^^^^^^^^^^^^^^^^^
After applying this patch you can disable the sendmsg() workaround code
in mars_nwe/emutli.c by setting DO_IPX_SEND_TEST to 0.
#define DO_IPX_SEND_TEST 0

!! this kernelpatch is _not_ needed for kernel >= 1.3.60 :) !!
this kernelpatch for clean kernels 1.3.56,57,58, pur 59 makes 3 things.
- removes the ipx-send bug. BIG THANKS to Volker Lendecke.
the problem was that sometimes the sendto function hung.
- ipx rip/sap packets comming from internal net must change
there source address from internal net/node to the
device net/node.
The problem was:
By configuring mars_nwe at the internal network, the rip/sap
socket gets the network and node address of the internal
net. Then, by sending rip/sap packets over this socket to the
several devices the rip/sap packets don't have the device net/node,
but the internal net/node.
- an existing route should never be overwritten by an route
over the internal net.
The problem was:
By running dosemu at the same workstation as mars_nwe the
dosemu automaticly changes the route to a nearby server
to route over the internal network and this destroyed
the real route over a device to this server.
You must be supervisor and then you must start './patchme' .

The kernelpatch kpatch1.3.72 you can use directly for kernels 1.3.72 .. 1.3.77
The kernelpatch kpatch1.3.78 you can use directly for kernels 1.3.78,79 .. ??
but it should be easy to apply this patch to all kernels.
By older kernels 'sk->protinfo.af_ipx.' must become 'sk->' .
After applying this patch please rebuild mars_nwe (make clean)
for getting notice of new ioctl call 'SIOCIPXNCPCONN'.
This patch is only necessary to speed up mars_nwe. (ca. 30 .. 50 % )
Perhaps this patch will get a place in the kerneldistribution one day. :)
This kernelpatch was originally designed by Volker Lendecke.
