net: mvneta: Fix big endian issue in mvneta_txq_desc_csum()
This commit fixes the command value generated for CSUM calculation when running in big endian mode. The Ethernet protocol ID for IP was being unconditionally byte-swapped in the layer 3 protocol check (with swab16), which caused the mvneta driver to not function correctly in big endian mode. This patch byte-swaps the ID conditionally with htons. Cc: <stable@vger.kernel.org> # v3.13+ Signed-off-by: Thomas Fitzsimmons <fitzsim@fitzsim.org> Signed-off-by: David S.
