Subject: [PATCH net-next 0/3] mlxsw: Add fw_version_check devlink parameter

Shalom says:

Currently, drivers do not have the ability to skip the firmware version
check during their initialization flow. Hence, drivers will always flash
a compatible version. This prevents drivers from running the device with
a different firmware version for testing and/or debugging purposes. For
example, testing a firmware bug fix.

For these situations, the new devlink generic parameter,
fw_version_check, gives the ability to skip the version check and allows
drivers to run with a different firmware version than what is required
by the driver.

Patch #1 adds the new parameter to devlink. The other two patches, #2
and #3, add support for this parameter in the mlxsw driver.

Shalom Toledo (3):
  devlink: Add fw_version_check generic parameter
  mlxsw: core: Reset firmware after flash during driver initialization
  mlxsw: spectrum: Skip firmware version check based on devlink
    parameter
