3218 | * by a TG3_BDINFO entry in the chips SRAM area. When a packet arrives, | |
3219 | * it is first placed into the on-chip ram. When the packet's length | |
3220 | * is known, it walks down the TG3_BDINFO entries to select the ring. | |

3226 | * to the buffer post rings, and only the chip writes to the rx status | |
3227 | * rings, then cache lines never move beyond shared-modified state. | |
