I am trying to port the various offloads (checksum, TSO etc.) that I recently implemented for the Hyper-V network driver to a 2.6.32 kernel and while this code works on the upstream bits, TCP checksum offload does not seem to work on the 2.6.32 kernel. Would you know if there is a different way to turn on checksum offload on 2.6.32 kernels? I am setting the relevant feature flags: net->features = NETIF_F_SG | NETIF_F_RXCSUM | NETIF_F_IP_CSUM | NETIF_F_TSO; What I am observing is that when the skb is presented to the driver for transmission, The ip_summed field in the skb is set to 0. On the kernel tip, I see this value set to CHECKSUM_PARTIAL and the offloads work correctly on the kernel tip. The other difference I see is that on entry into the driver, the eth_hdr state is not correctly set in the skb. I need to invoke skb_reset_mac_header() to get this state correctly set. Any help would be greatly appreciated. Regards, K.
