From 29cc927ef5a6d2f1e8de0d3d9fc67877aa4b6af7 Mon Sep 17 00:00:00 2001 From: Jo-Philipp Wich Date: Fri, 23 Dec 2016 19:15:14 +0100 Subject: [PATCH] generic: ar8216: fix invalid bounds check imported from ChromeOS (FS#347) The priv->vlan_id member is of size AR8X16_MAX_VLANS, not AR8X16_MAX_PORTS, so check for the proper maximum value in order to avoid capping valid VLAN IDs to 7 (AR8X16_MAX_PORTS - 1).
