Function Documentation

◆ FILE_LICENCE()

FILE_LICENCE ( GPL2_OR_LATER_OR_UBDL )

◆ rarp_rx()

static int rarp_rx	(	struct io_buffer *	iobuf,
		struct net_device *netdev	__unused,
		const void *ll_dest	__unused,
		const void *ll_source	__unused,
		unsigned int flags	__unused
	)

static

Process incoming ARP packets.

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 is a dummy method which simply discards RARP packets.

                                                    {
         free_iob ( iobuf );
         return 0;
 }

References free_iob().

◆ rarp_ntoa()

static const char* rarp_ntoa ( const void *net_addr __unused )

static

Transcribe RARP address.

Parameters

net_addr RARP address

Return values

string "<RARP>"

This operation is meaningless for the RARP protocol.

         return "<RARP>";
 }

◆ __net_protocol

struct net_protocol rarp_protocol __net_protocol

Initial value:

        .net_proto = htons ( ETH_P_RARP ),
        .rx = rarp_rx,
        .ntoa = rarp_ntoa,
}
