Subject: net: mvneta: Fix big endian issue in mvneta_txq_desc_csum()
From: Thomas Fitzsimmons <[email protected]>
[ Upstream commit 0a1985879437d14bda8c90d0dae3455c467d7642 ]
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.
