◆ 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
iobufI/O buffer
netdevNetwork device
ll_destLink-layer destination address
ll_sourceLink-layer source address
flagsPacket flags
Return values
rcReturn status code

This is a dummy method which simply discards RARP packets.

55  {
56  free_iob ( iobuf );
57  return 0;
58 }
void free_iob(struct io_buffer *iobuf)
Free I/O buffer.
Definition: iobuf.c:145

References free_iob().

◆ rarp_ntoa()

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

Transcribe RARP address.

Parameters
net_addrRARP address
Return values
string"<RARP>"

This operation is meaningless for the RARP protocol.
