125327952Sdim * TBI_ACCEPT macro definition:
126317017Sdim *
127317017Sdim * This macro requires:
128317017Sdim *      adapter = a pointer to struct e1000_hw
129317017Sdim *      status = the 8 bit status field of the Rx descriptor with EOP set
130317017Sdim *      error = the 8 bit error field of the Rx descriptor with EOP set
131317017Sdim *      length = the sum of all the length fields of the Rx descriptors that
132317017Sdim *               make up the current frame
133317017Sdim *      last_byte = the last byte of the frame DMAed by the hardware
134317017Sdim *      max_frame_length = the maximum frame length we want to accept.
135317017Sdim *      min_frame_length = the minimum frame length we want to accept.
136317017Sdim *
137317017Sdim * This macro is a conditional that should be used in the interrupt
138317017Sdim * handler's Rx processing routine when RxErrors have been detected.
139317017Sdim *
140317017Sdim * Typical use:
141317017Sdim *  ...
142317017Sdim *  if (TBI_ACCEPT) {
143317017Sdim *      accept_frame = TRUE;
144317017Sdim *      e1000_tbi_adjust_stats(adapter, MacAddress);
145317017Sdim *      frame_length--;
146317017Sdim *  } else {
147317017Sdim *      accept_frame = FALSE;
