Hi,
I have tried with out configuring the IP address on the interface. but
still face the same problem.
I attached the debugger to the netmapcat and found that the packets were
getting discarded with tcp stack with reason being bad checksum. After this
I disabled the "tcp check sum offload" on the host machine (ethtool
--offload <interface> rx off tx off) then it started working.
with the host kernel I need not to disable the --offload of checksum. It
works fine. Is there anything which I should enable to make it working with
rump kernel ?
Thanks
