Success at porting the smc91x kernel driver at last!!

root@xcep:~# /usr/local/rtnet/sbin/rtping 127.0.0.1
Real-time PING 127.0.0.1 56(84) bytes of data.
64 bytes from 127.0.0.1: icmp_seq=1 time=86.0 us
64 bytes from 127.0.0.1: icmp_seq=2 time=87.6 us
64 bytes from 127.0.0.1: icmp_seq=3 time=78.7 us
64 bytes from 127.0.0.1: icmp_seq=4 time=76.5 us

The story continues ..

While rtping does seem to work to 127.0.0.1, I can't seem to persuade 
the neighboring PC to reply to pings. PC is using e100 eth driver, and 
is running Linux 2.6.35.9 with Xenomai 2.5.6. I can confirm that on the 
PC rtping to 127.0.0.1 works, too.

Also when using regular network driver modules on both systems, ping 
from one to another does work. There are only these two nodes 
interconnected over the hub on a dedicated subnet. What happens is that 
the nodes do not seem to discover each other ..

Attached are both rtnet.conf files, and some sh -x output of the rtnet 
start. In this setup I'm trying to use my embedded target (xcep) as 
RTnet master, and PC as slave. I've tried the other way around to no avail.

Here are outputs of rtifconfig too.
