rarp_rx()

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;
}

rarp_ntoa()

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.
