From: Martin Kaiser Date: Sun, 17 Apr 2022 10:22:18 +0000 (+0200) Subject: staging: r8188eu: the frame type is shifted out X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=bea6af5447fcbdc076dfaacc33db7e49a855f794;p=linux.git staging: r8188eu: the frame type is shifted out The index calculation in mgt_dispatcher does not use the frame type. The 4-bit right shift ignores protocol version and frame type.
