Subject: [PATCH net-next 4/5] mlxsw: core: Push minor/subminor fw version check into helper
Date: Sun, 6 Oct 2019 09:34:51 +0300 [thread overview]
Message-ID: <20191006063452.7666-5-idosch@idosch.org> (raw)
In-Reply-To: <20191006063452.7666-1-idosch@idosch.org>
From: Vadim Pasternak <vadimp@mellanox.com>
Add new API for FW "minor" and "subminor" version validation for
sharing it between "spectrum" and "minimal" drivers.
Use it in "spectrum" driver.
