[RFC PATCH v1 8/9] net: ipconfig: Force fw_devlink to unblock any devices that might probe

From: Saravana Kannan
Date: Thu May 26 2022 - 04:17:14 EST


If there are network devices that could probe without some of their
suppliers probing and those network devices are needed for IP auto
config to work, then fw_devlink=on might break that usecase by blocking
the network devices from probing by the time IP auto config starts.

So, when IP auto config is enabled, make sure fw_devlink doesn't block
the probing of any device that has a driver by the time we get to IP
auto config.
