ionic: remove lifs on fw reset

2020-03-30T18:40:50Z

When the FW RESET event comes to the driver from the firmware, or the fw_status goes to 0 (stopped) or to 0xff (no PCI connection), then shut down the driver activity. This event signals a FW upgrade where we need to quiesce all operations and wait for the FW to restart. The FW will continue the update process once it sees all the LIFs are reset. When the update process is done it will set the fw_status back to RUNNING. Meanwhile, the heartbeat check continues and when the fw_status is seen as set to running we can restart the driver operations. Signed-off-by: Shannon Nelson Signed-off-by: David S. Miller

ionic: check for linkup in watchdog

Add a link_status_check to the heartbeat watchdog. Signed-off-by: Shannon Nelson Signed-off-by: David S. Miller

ionic: fix fw_status read

2020-02-20T23:48:04Z

The fw_status field is only 8 bits, so fix the read. Also, we only want to look at the one status bit, to allow for future use of the other bits, and watch for a bad PCI read. Fixes: 97ca486592c0 ("ionic: add heartbeat check") Signed-off-by: Shannon Nelson Signed-off-by: David S. Miller

ionic: support sr-iov operations

2020-01-05T22:51:02Z

Add the netdev ops for managing VFs. Since most of the management work happens in the NIC firmware, the driver becomes mostly a pass-through for the network stack commands that want to control and configure the VFs. We also tweak ionic_station_set() a little to allow for the VFs that start off with a zero'd mac address. Signed-off-by: Shannon Nelson Signed-off-by: David S. Miller

ionic: add a watchdog timer to monitor heartbeat

Add a watchdog to periodically monitor the NIC heartbeat. Signed-off-by: Shannon Nelson Signed-off-by: David S. Miller

ionic: add heartbeat check

2019-10-26T03:52:36Z

Most of our firmware has a heartbeat feature that the driver can watch for to see if the FW is still alive and likely to answer a dev_cmd or AdminQ request. Signed-off-by: Shannon Nelson Signed-off-by: David S. Miller

ionic: Add basic adminq support

2019-09-05T07:24:43Z

Most of the NIC configuration happens through the AdminQ message queue. NAPI is used for basic interrupt handling and message queue management. These routines are set up to be shared among different types of queues when used in slow-path handling. Signed-off-by: Shannon Nelson Signed-off-by: David S. Miller

ionic: Add interrupts and doorbells

2019-09-05T07:24:43Z

The ionic interrupt model is based on interrupt control blocks accessed through the PCI BAR. Doorbell registers are used by the driver to signal to the NIC that requests are waiting on the message queues. Interrupts are used by the NIC to signal to the driver that answers are waiting on the completion queues. Signed-off-by: Shannon Nelson Signed-off-by: David S. Miller

ionic: Add basic lif support

2019-09-05T07:24:43Z

The LIF is the Logical Interface, which represents the external connections. The NIC can multiplex many LIFs to a single port, but in most setups, LIF0 is the primary control for the port. Signed-off-by: Shannon Nelson Signed-off-by: David S. Miller

ionic: Add port management commands

2019-09-05T07:24:43Z

The port management commands apply to the physical port associated with the PCI device, which might be shared among several logical interfaces. Signed-off-by: Shannon Nelson Signed-off-by: David S. Miller
