From 3e511778248403968e0a02857b7003f352669ba3 Mon Sep 17 00:00:00 2001 From: Vadim Pasternak Date: Wed, 13 Jan 2021 13:19:17 +0200 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".
