From 59542c9ac9acd470c4fa3182792de91b4c2f6421 Mon Sep 17 00:00:00 2001 From: Olliver Schinagl Date: Mon, 31 Oct 2022 14:02:52 +0100 Subject: [PATCH] realtek: Fix rtl930x speed status accessor The rtl930x speed status registers require 4 bits to indicate the speed status. As such, we want to divide by 8. To make things consistent with the rest of this code, use a bitshift however. This bug probably won't affect many users yet, as there aren't many rtl930x switches in the wild yet with more then 10 ports, and thus a low-impact bugfix.
