Subject: [PATCH net-next 0/4] net: dsa: Improve dsa_untag_bridge_pvid()

Hi David, Jakub,

This patch series is based on the recent discussions with Vladimir:

https://lore.kernel.org/netdev/20201001030623.343535-1-f.fainelli@gmail.com/

the simplest way forward was to call dsa_untag_bridge_pvid() after
eth_type_trans() has been set which guarantees that skb->protocol is set
to a correct value and this allows us to utilize
__vlan_find_dev_deep_rcu() properly without playing or using the bridge
master as a net_device reference.

Florian Fainelli (4):
  net: dsa: Call dsa_untag_bridge_pvid() from dsa_switch_rcv()
  net: dsa: b53: Set untag_bridge_pvid
  net: dsa: Obtain VLAN protocol from skb->protocol
  net: dsa: Utilize __vlan_find_dev_deep_rcu()
