[c-nsp] 7206 input, ignored and rx_resource_error errors

[Dimitris Pantzartzis]

I have errors in a ge interface. The error count is 
the same for input, ignored and rx_resource_error

there are no overrun errors and have:

  Input queue: 0/75/3/0 (size/max/drops/flushes); Total output drops: 0

Any ideas what might  cause this and how to resolve?
