* TBI_ACCEPT macro definition:

* status = the 8 bit status field of the Rx descriptor with EOP set
* error = the 8 bit error field of the Rx descriptor with EOP set
* length = the sum of all the length fields of the Rx descriptors that
* make up the current frame
* last_byte = the last byte of the frame DMAed by the hardware
* max_frame_length = the maximum frame length we want to accept.
* min_frame_length = the minimum frame length we want to accept.
*
* This macro is a conditional that should be used in the interrupt

* e1000_tbi_adjust_stats(adapter, MacAddress);
* frame_length--;
* } else {
