Re: [PATCH net-next] net: stmmac: add tc-ets qdisc offload

Hi Lorenzo,

Implement offload of the tc-ets qdisc in the stmmac driver. The number
of ETS bands cannot exceed the number of TX queues, and mixing strict
priority bands (zero quanta) with weighted bands is rejected.

When all bands are strict priority, the MTL scheduler is programmed with
SP scheduling; otherwise the requested weights are applied to the TX
queues and the scheduler is switched to DWRR. The TC_ETS_STATS command
is accepted and handled.

Export stmmac_set_tx_queue_weight() so the ETS path can reprogram queue
weights, and wire TC_SETUP_QDISC_ETS into stmmac_setup_tc().

From my very small understanding of ETS, this looks good to me.
