Subject: [PATCH net-next 0/3] TX max rate limiting for Chelsio T4/T5 adapters

This series of patches implement tx max rate limiting per queue on
Chelsio T4/T5 hardware.  This is achieved by first creating a tx
scheduling class with the specified max rate.  The queue is then
bound to the newly created class.  If a scheduling class with similar
max rate already exists, then the queue is bound to the matching class.

Patch 1 adds support for setting tx scheduling classes.
Patch 2 adds support to bind/unbind queues to/from the scheduling classes.
Patch 3 implements the set_tx_maxrate NDO.

Rahul Lakkireddy (3):
  cxgb4: add support for tx traffic scheduling classes
  cxgb4: add support for per queue tx scheduling
  cxgb4: add support for tx max rate limiting
