Fnic: Memcopy only mimumum of data or trace buffer
In case of receive path, we do not have eth header or fcoe header available
when we take a trace so we fill the fc trace buffer with 0xff for both
values. We copy only mimimum of received data or trace buffer size -
fc header - eth and fcoe header
- Increment fnic version from 1.6.0.12 to 1.6.0.13
