I studied this and it's merely a matter of parameter passing.
Specifically, at ptype->func() time, it is plainly the skb->dev
before skb_bond() is applied.
So I added a "real_dev" arg to ptype->func() and converted
the tree over to that.
Thomas, this kills the TCF_META_ID_REALDEV stuff, so we should
kill it in 2.6.13-rcX too so that nobody starts using it in
userspace ok?
I'm trying to figure out if it matters for multiple levels of
decapsulation. As far as I can tell for the bond_3ad() case,
it doesn't, and that's the only user of this thing.
if_vlan.h was setting ->real_dev but that looked totally wrong
and had no usage, so I simply deleted that.
Comments?
