If you're using the Python wrapper, you can check the status of the ARP table
and core config easily with a little debug function that prints this info to
the screen. A correctly-configured 10GbE core should look something like this
(where I'm using IP addresses around 10.0.0.128):
In [1]: import corr
In [2]: f=corr.katcp_wrapper.FpgaClient('roach030186')
In [3]: f.print_10gbe_core_details('gbe0',arp=True)

BTW, tgtap should now be fully functional from katcp. I've tested it with
multiple cores and whatnot too. There's a function call in this same
katcp_wrapper for roach that lets you start (tap_start) and stop (tap_stop) it
easily. You must keep all identifiers to less than 8 characters long.
