Hmm. I bisected it. And my machine is broken by commit 8ad227ff89a7 ("net: vlan: add 802.1ad support"). I booted several times just to make sure, and it's consistent. The previous commit (86a9bad3ab6b) works fine, and 8ad227ff89a7 is broken. I don't see what could be broken in that commit, and I'd *like* to just revert it on top of current -git, but that causes problems ("error: ‘NETIF_F_HW_VLAN_STAG_TX_BIT’ undeclared"), so I can't just do a straight revert to double-check with the current tree state. But the bisection was very straightforward, and as mentioned, I checked that boundary several times just because it looked so odd. Maybe somebody who knows the code better just goes "Duh!". Anybody?
