From: Jiri Pirko <redacted>

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.  

Yeah, eventually you can get it. But still, it is unusable to check the
offload flag cause it has no relation with the block cbs.

OK.  Depends on which flags you intend to check.  I.e. is it OK to
offload filters of the bond, because all its slaves have offloads on
but the bond itself doesn't.  Is that what you mean?
