Cpsw_CrcType | crcType |
bool | removeCrc |
bool | padShortPacket |
bool | passCrcErrors |
uint32_t | rxMtu |
bool | passPriorityTaggedUnchanged |
bool | enableCsumOffload |

CpswPort_VlanConfig | vlanCfg |
CpswHostPort_RxPriorityType | rxPriorityType |
CpswPort_TxPriorityType | txPriorityType |
Cpsw_CrcType CpswHostPort_Config::crcType |
Type of CRC on all port 0 egress, regardless of the CRC type in Ethernet port ingress
bool CpswHostPort_Config::removeCrc |
Whether or not CRC is removed on port 0 egress
bool CpswHostPort_Config::padShortPacket |
Whether short packets (ingress) are padded to 64-bytes or dropped
bool CpswHostPort_Config::passCrcErrors |
Whether packets with CRC errors (ingress) are dropped or transferred to the destination ports
uint32_t CpswHostPort_Config::rxMtu |
Max length of a received frame on ingress, including VLAN
bool CpswHostPort_Config::passPriorityTaggedUnchanged |
Whether priority tagged packets should be passed unchanged (if set to true) or replaced with port's VID (if set to false)
bool CpswHostPort_Config::enableCsumOffload |
Enable checksum offload feature which allows TCP checksum computation to be offloaded to the CPSW for frames transmitted by any core. The Protocol specific info needs to be populated in the descriptor to indicate the location in the packet where the computed checksum should be inserted
bool CpswHostPort_Config::enableRxVlanRemap |
RX VLAN remap controls whether the hardware switch priority for VLAN tagged or priority tagged packets is determined from CPPI thread number (remap disabled) or via CPSW_HOSTPORT_IOCTL_SET_TX_PRIORITY (remap enabled)
bool CpswHostPort_Config::enableRxDscpIPv4Remap |
RX DSCP IPv4 remap controls whether the hardware switch priority for IPv4 packets is determined from CPPI thread number (remap disabled) or via CPSW_HOSTPORT_IOCTL_SET_TX_PRIORITY (remap enabled)
bool CpswHostPort_Config::enableRxDscpIPv6Remap |
RX DSCP IPv6 remap controls whether the hardware switch priority for IPv6 packets is determined from CPPI thread number (remap disabled) or via CPSW_HOSTPORT_IOCTL_SET_TX_PRIORITY (remap enabled)
CpswPort_VlanConfig CpswHostPort_Config::vlanCfg |
Port VLAN configuration
CpswHostPort_RxPriorityType CpswHostPort_Config::rxPriorityType |
Ingress priority type
CpswPort_TxPriorityType CpswHostPort_Config::txPriorityType |
Egress priority type
