net/mlx5: DR, Fix crc32 calculation to work on big-endian (BE) CPUs

Browse source

commit 1e5daf5565 upstream.

When calculating crc for hash index we use the function crc32 that
calculates for little-endian (LE) arch.
Then we convert it to network endianness using htonl(), but it's wrong
to do the conversion in BE archs since the crc32 value is already LE.

The solution is to switch the bytes from the crc result for all types
of arc.
