Merge branch 'vlan-untag-and-insert-fixes'
Toshiaki Makita says:
====================
Fix vlan untag and insertion for bridge and vlan with reorder_hdr off
As Brandon Carpenter reported[1], sending non-vlan-offloaded packets from
bridge devices ends up with corrupted packets. He narrowed down this problem
and found that the root cause is in skb_reorder_vlan_header().
While I was working on fixing this problem, I found that the function does
not work properly for double tagged packets with reorder_hdr off as well.
Patch 1 fixes these 2 problems in skb_reorder_vlan_header().
And it turned out that fixing skb_reorder_vlan_header() is not sufficient
to receive double tagged packets with reorder_hdr off while I was testing the
fix. Vlan tags got out of order when vlan devices with reorder_hdr disabled
were stacked. Patch 2 fixes this problem.
