Hi Kuma,

1) The ROACH2 does not support XPORT (that was only for the ROACH1). - You
can find the hardware specs of both on the old wiki:
https://casper.astro.berkeley.edu/wiki/ROACH,
https://casper.astro.berkeley.edu/wiki/ROACH-2_Revision_2)

2) As (1) above.

3) The V6 Net interface is a direct connection to the FPGA, instead of the
PPC chip, so you can use it e.g. for 1Gb Ethernet transmission from the
FPGA.

Cheers,
Jonathon
