From 43fb622d91a9f408322735d2f736495c1009f575 Mon Sep 17 00:00:00 2001 From: "Russell King (Oracle)" Date: Tue, 9 May 2023 12:50:04 +0100 Subject: [PATCH] net: pcs: xpcs: fix incorrect number of interfaces In synopsys_xpcs_compat[], the DW_XPCS_2500BASEX entry was setting the number of interfaces using the xpcs_2500basex_features array rather than xpcs_2500basex_interfaces. This causes us to overflow the array of interfaces. Fix this.
