Detailed Description

Field Documentation

◆ name

const char* net_protocol::name

Protocol name.

Definition at line 66 of file netdevice.h.

Referenced by arp_rx(), arp_tx_request(), efi_pxe_udp_read(), neighbour_create(), neighbour_destroy(), neighbour_discover(), neighbour_discovered(), neighbour_expired(), neighbour_tx(), nstat(), pxenv_undi_isr(), and pxenv_undi_transmit().

◆ rx

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

Process received packet.

Parameters

iobuf	I/O buffer
netdev	Network device
ll_dest	Link-layer destination address
ll_source	Link-layer source address
flags	Packet flags

Return values

rc	Return status code

This method takes ownership of the I/O buffer.

Definition at line 79 of file netdevice.h.

Referenced by net_rx().

◆ ntoa

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.

◆ net_proto

uint16_t net_protocol::net_proto

Network-layer protocol.

This is an ETH_P_XXX constant, in network-byte order
