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 no means of testing this as I do not have any bnx2x hardware but
thought I would submit it as an RFC to see if anyone out there wants to
test this and see if this does in fact enable this functionality allowing
us to to segment tunneled frames that have an outer checksum.
