Subject: ipvlan: use netif_receive_skb() in ipvlan_process_multicast()
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=d0273dbe8be1640e597552f81faf1d6c9997d3e3;p=thirdparty%2Flinux.git

ipvlan: use netif_receive_skb() in ipvlan_process_multicast()

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.
