Subject: sfc: Convert firmware subtypes to native byte order in efx_mcdi_get_board_cfg()
From: Ben Hutchings <bhutchings@xxxxxxxxxxxxxx>
[ Upstream commit bfeed902946a31692e7a24ed355b6d13ac37d014 ]
On big-endian systems the MTD partition names currently have mangled
subtype numbers and are not recognised by the firmware update tool
(sfupdate).
Signed-off-by: Ben Hutchings <bhutchings@xxxxxxxxxxxxxx>
[bwh: Backported to 3.0: use old macros for length of firmware subtype array]
