[PATCH v5 2/3] staging: r8188eu: incorrect type in csum_ipv6_magic

From: Aakash Hemadri
Date: Sat Aug 28 2021 - 07:11:01 EST


Fix sparse warning:
> rtw_br_ext.c:771:84: got restricted __be16 [usertype] payload_len
> rtw_br_ext.c:773:110: warning: incorrect type in argument 2
(different base types)
> rtw_br_ext.c:773:110: expected int len
> rtw_br_ext.c:773:110: got restricted __be16 [usertype] payload_len

csum_ipv6_magic and csum_partial expect int len not __be16, use
be16_to_cpu()
