Subject: [PATCH net-next 0/8] mlxsw: Various updates
Patches #1-#3 add missing topology diagrams in selftests and perform
small cleanups.
Patches #4-#5 make small adjustments in QoS configuration. See detailed
description in the commit messages.
Patches #6-#8 reduce the number of background EMAD transactions. The
driver periodically queries the device (via EMAD transactions) about
updates that cannot happen in certain situations. This can negatively
impact the latency of time critical transactions, as the device is busy
processing other transactions.
