Hidetoshi Shimokawa 2b4601d10b MFp4(simokawa_sbp)
Improve if_fwe performance.
- Simplify mbuf handling by using bulkxfer.
	Now, it uses mbuf clusters for RX buffer as usual ethernet drivers.
- Recycle struct xfer buffer and don't call malloc at runtime.
- Count input and output errors.
- Handle a mbuf chain longer than 6 correctly.
- Increase queue length.
