From c0fae7e2452b90c31edd2d25eb3baf0c76b400ca Mon Sep 17 00:00:00 2001 From: Aaro Koskinen Date: Sat, 27 Oct 2018 01:46:34 +0300 Subject: [PATCH] MIPS: OCTEON: fix out of bounds array access on CN68XX The maximum number of interfaces is returned by cvmx_helper_get_number_of_interfaces(), and the value is used to access interface_port_count[]. When CN68XX support was added, we forgot to increase the array size. Fix that.
