    be2net: Extend xmit workaround to BE3 chip
    
    [ Upstream commit 7580e0a78eb29e7bb1a772eba4088250bbb70d41 ]
    
    We have seen a bug where the NIC incorrectly changes the length in the
    IP header of a padded packet to include the padding bytes. The driver
    already has a workaround for this so do the workaround for this NIC too.
    This resolves the issue.
    
    The NIC in question identifies itself as follows:
    
    [    8.828494] be2net 0000:02:00.0: FW version is 10.7.110.31
    [    8.834759] be2net 0000:02:00.0: Emulex OneConnect(be3): PF FLEX10 port 1
    
    02:00.0 Ethernet controller: Emulex Corporation OneConnect 10Gb NIC (be3) (rev 01)
