- TODO:
- * Test Tx checksumming thoroughly
-
- Low priority TODO:
- * Complete reset on PciErr
- * Consider Rx interrupt mitigation using TimerIntr
- * Investigate using skb->priority with h/w VLAN priority
- * Investigate using High Priority Tx Queue with skb->priority
- * Adjust Rx FIFO threshold and Max Rx DMA burst on Rx FIFO error
- * Adjust Tx FIFO threshold and Max Tx DMA burst on Tx FIFO error
- * Implement Tx software interrupt mitigation via
- Tx descriptor bit
- * The real minimum of CP_MIN_MTU is 4 bytes. However,
- for this to be supported, one must(?) turn on packet padding.
- * Support external MII transceivers (patch available)
-
- NOTES:
- * TX checksumming is considered experimental. It is off by
- default, use ethtool to turn it on.
