[c-nsp] WS-X6708-10G-3C and 3CXL and SUP720-3BXL

[Lee Starnes]

Thanks Aled. Yep, I would prefer not to get onto that upgrade treadmill at
this time. Everything is operating just fine with the 3BXLs, and until we
start to push more than 20G on these chassis, I would prefer to keep them
this way.

Thanks for the info.
