Subject: [PATCH net-next 1/4] net: xilinx: axienet: Always disable promiscuous mode

From: Sean Anderson <[email-masked]>
Date: Mon, 12 Aug 2024 16:04:34 -0400

If prmiscuous mode is disabled when there are fewer than four multicast
addresses, then it will to be reflected in the hardware. Fix this by
always clearing the promiscuous mode flag even when we program multicast
addresses.
