CASSINI: Fix endianness bug.
[ Upstream commit: e5e025401f6e926c1d9dc3f3f2813cf98a2d8708 ] 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. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk> Signed-off-by: David S.
