Both of these operations require acquiring\nthe netdev instance lock.\n\nMove the call to `packet_dev_mc` outside of the RCU critical section.\nThe `mclist` modifications (add, del, flush, unregister) are protected by\nthe RTNL, not the RCU. The RCU only protects the `sklist` and its\nassociated `sks`. The delayed operation on the `mclist` entry remains\nwithin the RTNL.",
