i.MX28 EMAC and IP accelerator functions

Hi all,

I am trying to enable IP header checksum insertion by the EMAC on the transmit path.

Although I set bit 3 (TX_IPCHK_INS) of register HW_ENET_MAC_IPACCTXCONF it does

not seem to have any effect. When I capture the packet with Wireshark the checksum

is still 0. Does this feature work in the legacy DMA mode?

I noticed that in the enhanced DMA mode this feature can be enabled via a control bit

on the DMA descriptor too.

Regards,

Stathis
