We are using the 2.2.12 kernel with kdb added from SGI's
kdb-v0.5-2.2.10. We suspect that there is conflict when more than
protocol plugs into the same network driver.
We have a loadable module which plugs into the network driver to use
the network interfaces:
on->proto.type = protocol_type;
on->proto.dev = dev; // 3com for the panic below
on->proto.func = OSD_NET_input;
on->proto.data = (void *)on;
dev_add_pack(&on->proto);
The hardware configuration we are using has 2 3com (3c59x) and one
Intel EEPRO100 NICs.
Several times while our module was plugged into the network drivers,
we ran multiple ttcp copies, e.g.,
ttcp -s -u -l32 -p 2000 -n 65536 -t dest-host
with a corresponding receiver on the other side. We encountered a
panic which is shown below through kdb outputs.
Does anyone have suggestions how we can solve this problem, or ideas
how to register multiple protocols with a driver? (We looked briefly
at the IPX and Appletalk interfaces, but they appeared to use an older
version of the skb interface).
