Subject: [PATCH net-next] ipvlan: use netif_receive_skb() in ipvlan_process_multicast()
Date: Mon, 27 Apr 2026 09:36:33 +0000 [thread overview]
Message-ID: <20260427093633.979310-1-edumazet@google.com> (raw)
ipvlan_process_multicast() runs from process context, there is no
risk of stack overflow if we call netif_receive_skb() instead
of netif_rx().
This avoids some overhead adding/removing skbs to/from a per-cpu
backlog and raising/processing NET_RX softirqs.
