From 43becaa5cd76da3d6049c3ab720e6bd840b66570 Mon Sep 17 00:00:00 2001 From: Stefan Wahren Date: Wed, 30 Apr 2025 15:30:41 +0200 Subject: [PATCH] net: vertexcom: mse102x: Fix LEN_MASK [ Upstream commit 74987089ec678b4018dba0a609e9f4bf6ef7f4ad ] The LEN_MASK for CMD_RTS doesn't cover the whole parameter mask. The Bit 11 is reserved, so adjust LEN_MASK accordingly.
