Field Documentation

dev

const char* cb_socket_lldcfg_update_t::dev

Device name to match the expected socket.

proto

uint16_t cb_socket_lldcfg_update_t::proto

Protocol or ethernet type in the ethernet frame header to match the expected socket.

vlanid

uint16_t cb_socket_lldcfg_update_t::vlanid

VLAN ID to match the expected socket.

nTxPkts

uint32_t cb_socket_lldcfg_update_t::nTxPkts

Number of buffers allocated for transmit packets Positive value will be updated to LLDEnetCfg_t.

nRxPkts

uint32_t cb_socket_lldcfg_update_t::nRxPkts[MAX_NUM_RX_DMA_CH_PER_INSTANCE]

Number of buffers allocated for receive packets Positive value will be updated to LLDEnetCfg_t.

pktSize

uint32_t cb_socket_lldcfg_update_t::pktSize

Transmit and receive maximum packet size. Positive value will be updated to LLDEnetCfg_t.

dmaTxChId

int cb_socket_lldcfg_update_t::dmaTxChId

DMA transmit channel ID. 0 or positive value will be updated to LLDEnetCfg_t

dmaRxChId

int cb_socket_lldcfg_update_t::dmaRxChId[MAX_NUM_RX_DMA_CH_PER_INSTANCE]

DMA receive channel ID. 0 or positive value will be updated to LLDEnetCfg_t

unusedDmaRx

int cb_socket_lldcfg_update_t::unusedDmaRx

>0: won't use DMA RX; 0: will use DMA RX 0 or positive value will be updated to LLDEnetCfg_t

unusedDmaTx

int cb_socket_lldcfg_update_t::unusedDmaTx

>0: won't use DMA TX; 0: will use DMA TX 0 or positive value will be updated to LLDEnetCfg_t

dmaRxShared

int cb_socket_lldcfg_update_t::dmaRxShared

Only Sitara AM273x support this param. >0: the dmaRxChId is shared between apps; 0: not shared 0 or positive value will be updated to LLDEnetCfg_t

dmaRxOwner

int cb_socket_lldcfg_update_t::dmaRxOwner

Only Sitara AM273x support this param. >0: the socket owns this RX DMA channel; 0: not own 0 or positive value will be updated to LLDEnetCfg_t

rxDefaultDataCb

void(* cb_socket_lldcfg_update_t::rxDefaultDataCb) (void *data, int size, int port, void *cbArg)

Only Sitara AM273x support this param. Default RX data callback when there is no matching RX filter.

rxDefaultCbArg

void* cb_socket_lldcfg_update_t::rxDefaultCbArg

Only Sitara AM273x support this param. Default RX data callback arg

numRxChannels

uint32_t cb_socket_lldcfg_update_t::numRxChannels

Number of Rx DMA channels, only ICSSG peripheral has more than 1 Rx DMA channels.
