Merge branch 'alx-multiqueue-support'
Tobias Regnery says: ==================== alx: add multi queue support This patchset lays the groundwork for multi queue support in the alx driver and enables multi queue support for the tx path by default. The hardware supports up to 4 tx queues. Benefits are better utilization of multi core cpus and the usage of the msi-x support by default which splits the handling of rx / tx and misc other interrupts. The rx path is a little bit harder because apparently (based on the limited information from the downstream driver) the hardware supports up to 8 rss queues but only has one hardware descriptor ring on the rx side. So the rx path will be part of another patchset. Tested on my AR8161 ethernet adapter with different tests: - there are no regressions observed during my daily usage - iperf tcp and udp tests shows no performance regressions - netperf TCP_RR and UDP_RR shows a slight performance increase of about 1-2% with this patchset applied This work is based on the downstream driver at github.com/qca/alx Changes in V2: - drop unneeded casts in alx_alloc_rx_ring (Patch 1) - add additional information about testing and benefit to the changelog ==================== Signed-off-by: David S.
