- * Assumptions made in this code:
- * - The IXP2400 MSF is configured for POS-PHY mode, in a mode where

- * 1x32 SPHY and 1x32 MPHY32, but not 4x8 SPHY or 1x32 MPHY4. (This
- * is not an exhaustive list.)
- * - The RBUF uses 64-byte mpackets.
- * - RX descriptors reside in SRAM, and have the following format:
- * struct rx_desc
- * {
- * // to uengine
- * u32 buf_phys_addr;
- * u32 buf_length;
- *
- * // from uengine
- * u32 channel;
- * u32 pkt_length;
- * };
- * - Packet data resides in DRAM.
- * - Packet buffer addresses are 8-byte aligned.
- * - Scratch ring 0 is rx_pending.
- * - Scratch ring 1 is rx_done, and has status condition 'full'.
- * - The host triggers rx_done flush and rx_pending refill on seeing INTA.
- * - This code is run on all eight threads of the microengine it runs on.
- *
- * Local memory is used for per-channel RX state.

- * Assumptions made in this code:
- * - The IXP2400 MSF is configured for POS-PHY mode, in a mode where
- * only one TBUF partition is used. This includes, for example,
- * 1x32 SPHY and 1x32 MPHY32, but not 4x8 SPHY or 1x32 MPHY4. (This
- * is not an exhaustive list.)
- * - The TBUF uses 64-byte mpackets.
- * - TX descriptors reside in SRAM, and have the following format:
- * struct tx_desc
- * {
- * // to uengine
- * u32 buf_phys_addr;
- * u32 pkt_length;
- * u32 channel;
- * };
- * - Packet data resides in DRAM.
- * - Packet buffer addresses are 8-byte aligned.
- * - Scratch ring 2 is tx_pending.
- * - Scratch ring 3 is tx_done, and has status condition 'full'.
- * - This code is run on all eight threads of the microengine it runs on.
