From f2ccd8fa06c8e302116e71df372f5c1f83432e03 Mon Sep 17 00:00:00 2001

Subject: [PATCH] [NET]: Kill skb->real_dev

Bonding just wants the device before the skb_bond()
decapsulation occurs, so simply pass that original
device into packet_type->func() as an argument.

It remains to be seen whether we can use this same
exact thing to get rid of skb->input_dev as well.
