| 4551 | * by a TG3_BDINFO entry in the chips SRAM area. When a packet arrives, |
| 4552 | * it is first placed into the on-chip ram. When the packet's length |
| 4553 | * is known, it walks down the TG3_BDINFO entries to select the ring. |

| 4560 | * rings, then cache lines never move beyond shared-modified state. |
