127 * TBI_ACCEPT macro definition:
128 *
129 * This macro requires:
130 *      adapter = a pointer to struct e1000_hw
131 *      status = the 8 bit status field of the Rx descriptor with EOP set
132 *      error = the 8 bit error field of the Rx descriptor with EOP set
133 *      length = the sum of all the length fields of the Rx descriptors that
134 *               make up the current frame
135 *      last_byte = the last byte of the frame DMAed by the hardware
136 *      max_frame_length = the maximum frame length we want to accept.
137 *      min_frame_length = the minimum frame length we want to accept.
138 *
139 * This macro is a conditional that should be used in the interrupt
140 * handler's Rx processing routine when RxErrors have been detected.
141 *
142 * Typical use:
143 *  ...
144 *  if (TBI_ACCEPT) {
145 *      accept_frame = TRUE;
146 *      e1000_tbi_adjust_stats(adapter, MacAddress);
147 *      frame_length--;
148 *  } else {
149 *      accept_frame = FALSE;
150 *  }
