Merge branch 'configuring-congestion-watermarks-on-ocelot-switch-using-devlink-sb'
Vladimir Oltean says: ==================== Configuring congestion watermarks on ocelot switch using devlink-sb In some applications, it is important to create resource reservations in the Ethernet switches, to prevent background traffic, or deliberate attacks, from inducing denial of service into the high-priority traffic. These patches give the user some knobs to turn. The ocelot switches support per-port and per-port-tc reservations, on ingress and on egress. The resources that are monitored are packet buffers (in cells of 60 bytes each) and frame references. The frames that exceed the reservations can optionally consume from sharing watermarks which are not per-port but global across the switch. There are 10 sharing watermarks, 8 of them are per traffic class and 2 are per drop priority. I am configuring the hardware using the best of my knowledge, and mostly through trial and error. Same goes for devlink-sb integration. Feedback is welcome. ==================== Link: https://lore.kernel.org/r/20210115021120.3055988-1-olteanv@gmail.comSigned-off-by: Jakub Kicinski <kuba@kernel.org>
