Date: Sun, 3 Mar 2019 09:12:06 +0000 From: Ido Schimmel <idosch@...lanox.com> To: "netdev@...r.kernel.org" <netdev@...r.kernel.org> CC: "davem@...emloft.net" <davem@...emloft.net>, Jiri Pirko <jiri@...lanox.com>, Vadim Pasternak <vadimp@...lanox.com>, mlxsw <mlxsw@...lanox.com>, Ido Schimmel <idosch@...lanox.com> Subject: [PATCH net-next 0/8] mlxsw: minimal: Add ethtool and resource query support Vadim says: The minimal driver is chip independent and uses I2C bus for chip access. Its purpose is to support chassis management on systems equipped with Mellanox switch ASICs. For example, from a BMC (Board Management Controller) device. Patches #1-#3 add ethtool support to the minimal driver so that QSFP/SFP module info could be retrieved by the driver. This is done by exposing a dummy netdev for each front panel port and implementing the required ethtool operations. Patches #4-#8 add resource query support. This allows the driver to query the firmware about values of certain resources (e.g., maximum number of ports). It is required on systems where the maximum number of ports is larger than the hard coded default (64).
