123 | /* | |
124 | * TBI_ACCEPT macro definition: | |
125 | * | |
126 | * This macro requires: | |
127 | * a = a pointer to struct e1000_hw | |
128 | * status = the 8 bit status field of the Rx descriptor with EOP set | |
129 | * errors = the 8 bit error field of the Rx descriptor with EOP set | |
130 | * length = the sum of all the length fields of the Rx descriptors that | |
131 | * make up the current frame | |
132 | * last_byte = the last byte of the frame DMAed by the hardware | |
133 | * min_frame_size = the minimum frame length we want to accept. | |
134 | * max_frame_size = the maximum frame length we want to accept. | |
135 | * | |
136 | * This macro is a conditional that should be used in the interrupt | |
137 | * handler's Rx processing routine when RxErrors have been detected. | |
138 | * | |
139 | * Typical use: | |
140 | * ... | |
141 | * if (TBI_ACCEPT) { | |
142 | * accept_frame = true; | |
143 | * e1000_tbi_adjust_stats(adapter, MacAddress); | |
144 | * frame_length--; | |
145 | * } else { | |
146 | * accept_frame = false; | |
147 | * } | |
