[PATCH 7/8] net: qualcomm: rmnet: mark endianness of struct rmnet_map_dl_csum_trailer fields

From: Alex Elder
Date: Mon May 20 2019 - 09:56:35 EST


Two 16-bit fields (csum_start_offset and csum_length) in the
rmnet_map_dl_csum_trailer structure are currently defined to have
type u16. But they are in fact big endian values, so should be
properly represented as __be16 values.

No existing code actually references these fields (they're ignored by
rmnet_map_ipv4_dl_csum_trailer() and rmnet_map_ipv6_dl_csum_trailer()).
Changing their type therefore causes no harm, so just fix them.
