Couple of classifiers call netif_keep_dst directly on q->dev. That is
not possible to do directly for shared blocke where multiple qdiscs are
owning the block. So introduce a infrastructure to keep track of the
block owners in list and use this list to implement block variant of
netif_keep_dst.

Could you use the list you add here to check the ethtool tc offload
flag? :)  

It is a list of qdisc sub parts. Not a list of netdevs

Hm.  OK, I won't pretend I understand the TC code in detail, I thought
that would give you all netdevs, but possibly duplicated.
