    This patch assumes that the bnxt hardware will ignore existing IPv4/v6
    header fields for length and checksum as well as the length and checksum
    fields for outer UDP and GRE headers.
    
    I have been told by Michael Chan that this is working.  Though this might
    be somewhat redundant for IPv6 as they are forcing the checksum to be
    computed for all IPv6 frames that are offloaded.  A follow-up patch may be
    necessary in order to fix this as it is essentially mangling the outer IPv6
    headers to add a checksum where none was requested.
