    [CASSINI]: Fix endianness bug. · e5e02540
    Al Viro authored
    Here's proposed fix for RX checksum handling in cassini; it affects
    little-endian working with half-duplex gigabit, but obviously needs
    testing on big-endian too.
    
    The problem is, we need to convert checksum to fixed-endian *before*
    correcting for (unstripped) FCS.  On big-endian it won't matter
    (conversion is no-op), on little-endian it will, but only if FCS is
    not stripped by hardware; i.e. in half-duplex gigabit mode when
    ->crc_size is set.
    
    cassini.c part is that fix, cassini.h one consists of trivial
    endianness annotations.  With that applied the sucker is endian-clean,
    according to sparse.
