Field Documentation

const char* net_protocol::name

Protocol name.

Definition at line 54 of file netdevice.h.

Referenced by arp_resolve(), arp_rx(), pxenv_undi_isr(), and pxenv_undi_transmit().

int( * net_protocol::rx)(struct io_buffer *iobuf, struct net_device *netdev, const void *ll_source)

Process received packet.

Parameters:

	iobuf	I/O buffer
	netdev	Network device
	ll_source	Link-layer source address

This method takes ownership of the I/O buffer.

Referenced by net_rx().

const char*( * net_protocol::ntoa)(const void *net_addr)

Transcribe network-layer address.

Parameters:

net_addr

Network-layer address

Return values:

string

Human-readable transcription of address

This method should convert the network-layer address into a human-readable format (e.g. dotted quad notation for IPv4).

The buffer used to hold the transcription is statically allocated.

uint16_t net_protocol::net_proto

Network-layer protocol.

This is an ETH_P_XXX constant, in network-byte order
