RE: Why is packet socket checked before bridge in netif_receive_skb?

["Simon Barber" <simon@xxxxxxxxxxxxxxx>]

The odd thing is that the 'all protocols' handlers are checked before
the bridge hook, but the protocol type specific handlers are checked
after. Hence if you bind your packet socket to 'all' protocols you get
packets before bridging, but if you bind to a specific protocol you get
packets after the bridge hook.

Perhaps so that one can look at frames entering on a specific interface
rather than the bridge as a whole?
