From 52f79609c0c5b25fddb88e85f25ce08aa7e3fb42 Mon Sep 17 00:00:00 2001 From: Jakub Kicinski Date: Thu, 8 Jun 2023 09:23:44 -0700 Subject: [PATCH] net: ethtool: correct MAX attribute value for stats When compiling YNL generated code compiler complains about array-initializer-out-of-bounds. Turns out the MAX value for STATS_GRP uses the value for STATS. This may lead to random corruptions in user space (kernel itself doesn't use this value as it never parses stats).
