+Subject: [PATCH] hw-mgmt: events: Add support for SDK OFFLINE event for
+ handling flow with in service firmware upgrade
+
+In order to prevent "mlxsw_minimal" driver access to ASIC during in
+service firmware upgrade flow, SDK will raise "OFFLINE" 'udev' event
+at early beginning of such flow. When this event is received,
+hw-managemnet will remove "mlxsw_minimal" driver.
+There is no need to implement opposite "ONLINE" event, since this flow
+is ended up with "kexec".
