These two patches can be used to set per queue bandwidth with ethtool. I've create them as logical continuation of patchset from intel, that have introduced per-queue setting command month ago for ethtool interface (http://kernel.opensuse.org/cgit/kernel-source/commit/?h=rpm-4.4.9-36&; id=feaab26abfffe381fb4c8c10d2762a753d481c6c). Actually I've not tested this interface and planning to send it in parallel with "net: ethernet: ti: cpsw: add multi-queue support" (https://lkml.org/lkml/2016/6/30/603), as it contains only changes to ethtool interface. First patch can be used to set per-channel bandwidth, second to tune number of per-channel descriptors. It can solve issues described by Schuyler. In case if per-channel bandwidth is equal to maximum for every channel, the driver could be switched to priority mode.
