From 4ae738dfef2c0323752ab81786e2d298c9939321 Mon Sep 17 00:00:00 2001 From: Sean Anderson Date: Thu, 22 Aug 2024 11:40:55 -0400 Subject: [PATCH] net: xilinx: axienet: Always disable promiscuous mode If promiscuous mode is disabled when there are fewer than four multicast addresses, then it will not be reflected in the hardware. Fix this by always clearing the promiscuous mode flag even when we program multicast addresses.
