    sfc: process RX event inner checksum flags · a0ee3541
    Jon Cooper authored
    Add support for RX checksum offload of encapsulated packets. This
     essentially just means paying attention to the inner checksum flags
     in the RX event, and if *either* checksum flag indicates a fail then
     don't tell the kernel that checksum offload was successful.
    Also, count these checksum errors and export the counts to ethtool -S.
    
    Test the most common "good" case of RX events with a single bitmask
     instead of a series of ifs.  Move the more specific error checking
     in to a separate function for clarity, and don't use unlikely() there
     since we know at least one of the bits is bad.
