From 2dbe5f19368caae63b1f59f5bc2af78c7d522b3a Mon Sep 17 00:00:00 2001 From: Doug Berger opendmb@gmail.com Date: Thu, 25 Apr 2024 15:27:20 -0700 Subject: [PATCH] net: bcmgenet: synchronize use of bcmgenet_set_rx_mode()

The ndo_set_rx_mode function is synchronized with the netif_addr_lock spinlock and BHs disabled. Since this function is also invoked directly from the driver the same synchronization should be applied.
