FILE_LICENCE

(

GPL2_OR_LATER

)

static int rarp_rx	(	struct io_buffer *	iobuf,
		struct net_device *netdev	__unused,
		const void *ll_source	__unused
	)			[static]

Process incoming ARP packets.

Parameters:

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

Return values:

rc

Return status code

This is a dummy method which simply discards RARP packets.

                                                      {
        free_iob ( iobuf );
        return 0;
}

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.
