[c-nsp] 7204vxr freeze-up question

Well, I strongly recommend replacing radio unit with another device. There
are some legacy gigabit intel chipset cards and they have problem while
transmitting even octets to Cisco GE interfaces. The workaround was to
update intel NIC drivers. If you believe that you have intel card than I
guess you can't update the drivers for your radio unit and you may need to
consult with vendor.
