From cc3a4cd3f016a081a29b938f1ad17669bfacc9b2 Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Sun, 21 Oct 2018 14:05:49 +0300 Subject: net/mlx5: Allocate enough space for the FDB sub-namespaces FDB_MAX_CHAIN is three. We wanted to allocate enough memory to hold four structs but there are missing parentheses so we only allocate enough memory for three structs and the first byte of the fourth one.
