Field Documentation

const char* tcpip_protocol::name

Protocol name.

int( * tcpip_protocol::rx) (struct io_buffer *iobuf, struct net_device *netdev, struct sockaddr_tcpip *st_src, struct sockaddr_tcpip *st_dest, uint16_t pshdr_csum)

Process received packet.

Parameters

iobuf	I/O buffer
netdev	Network device
st_src	Partially-filled source address
st_dest	Partially-filled destination address
pshdr_csum	Pseudo-header checksum

Return values

rc	Return status code

This method takes ownership of the I/O buffer.

uint16_t tcpip_protocol::zero_csum

Preferred zero checksum value.

The checksum is a one's complement value: zero may be represented by either positive zero (0x0000) or negative zero (0xffff).

This is a constant of the type IP_XXX
