Subject: [PATCH net-next V1 0/3] Add max rate TXQ attribute 

Add the ability to set a max-rate limitation for TX queues.
The attribute name is maxrate and the units are Mbs, to make
it similar to the existing max-rate limitation knobs (ETS and 
SRIOV ndo calls).

changes from V0:
  - addressed feedback from Sergei (thanks).

John, you suggested to add another way (e.g through netlink) to 
program the TXQ maxrate limit, I am OK to add that after we bake 
it a little further (see my response on V0). I would suggest to make 
progress on the current series which includes the basic ndo, TXQ sysfs 
entry & driver implementation, and add more injection points on top 
of it, once accepted, makes sense?

Or.
