TX Checksum Offload Engine Enable (TXCOE_EN). This bit enables/disables the Transmit COE.
This bit may only be changed if the TX data path is disabled.
0: The TXCOE is bypassed
1: The TXCOE is enabled
Reserved
RX Checksum Offload Engine Mode (RXCOE_MODE) This register indicates whether the RXCOE
will check for VLAN tags or a SNAP header prior to beginning its checksum calculation. In its default
mode, the calculation will always begin 14 bytes into the frame.
The RXCOE_MODE may only be changed if the ESS RX path is disabled.
0: Begin checksum calculation after first 14 bytes of Ethernet Frame
1: Begin checksum calculation at start of L3 packet by adjusting for VLAN tags and/or SNAP header.
RX Checksum Offload Engine Enable (RXCOE_EN). This bit enables/disables the Receive COE.
This bit may only be changed if the RX data path is disabled.
0: The RXCOE is bypassed
1: The RXCOE is enabled
Note:
COE_CR—Checksum Offload Engine Control Register
This register controls the transmit and receive checksum offload engines.
