The current ROS v6.x doesn't support our (me and my friends) NICs:
Solarflare SFN5122F/SFN6122F
Our NIC has support for:
"Linux® 2.6 and 3.x Kernels (32 bit and 64 bit) for the following distributions: RHEL 5, 6, 7 and MRG. SLES 10, 11 and SLERT."
And I also checked and its working in debian+ubuntu as well.

Please add support for this NIC and few more 10G NICs for ROS v7.
We'd really much appreciate it !
