EnetUdma_RxProtoInfo Struct Reference

Detailed Description

Enet UDMA RX Protocol Info structure.

It contains IPv4/IPv6 protocol information including checksum. This is copied from the CPPI TX status word (UDMA flow protocol specific info).

Field Documentation

ipv6Valid

bool EnetUdma_RxProtoInfo::ipv6Valid

Flag to indicate an IPv6 TCP or UDP Packet was detected

ipv4Valid

bool EnetUdma_RxProtoInfo::ipv4Valid

Flag to indicate an IPv4 TCP or UDP Packet was detected

tcpudpIndicator

bool EnetUdma_RxProtoInfo::tcpudpIndicator

TCP or UDP packet detected. Valid only if ipv4Valid or ipv6Valid is true

fragment

bool EnetUdma_RxProtoInfo::fragment

IP fragment detected. Valid only if ipv4Valid or ipv6Valid is true

chkSumErr

bool EnetUdma_RxProtoInfo::chkSumErr

Checksum error flag. Valid only if ipv4Valid or ipv6Valid is true

chkSum

uint16_t EnetUdma_RxProtoInfo::chkSum

Computed checksum value
