Otherwise, use lwIP facilities. Uses Raw API only.

#define PBUF_POOL_BUFSIZE LWIP_MEM_ALIGN_SIZE(TCP_MSS+40+PBUF_LINK_HLEN+4)

PBUF_POOL_BUFSIZE: the size of each pbuf in the pbuf pool.

The default is designed to accomodate single full size TCP frame in one pbuf, including TCP_MSS, IP header, and link header.

NOTE: Added extra word to handle Micrel requirement.

Referenced by ksz8851snl_rx_populate_queue().

#define PBUF_POOL_SIZE 5

#define TCP_MSS 1460

TCP_MSS: The maximum segment size controls the maximum amount of payload bytes per packet.

For maximum throughput, set this as high as possible for your network (i.e. 1460 bytes for standard ethernet). For the receive side, this MSS is advertised to the remote side when opening a connection. For the transmit size, this MSS sets an upper limit on the MSS advertised by the remote host.
