2020-05-12ionic: call ionic_port_init after fw-upgradeShannon Nelson1-9/+9
Since the fw has been re-inited, we need to refresh the port information dma address so we can see fresh port information. Let's call ionic_port_init again, and tweak it to allow for a call to simply refresh the existing dma address.

2020-03-30ionic: remove lifs on fw resetShannon Nelson1-3/+5
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.

2020-03-21ionic: check for NULL structs on teardownShannon Nelson1-1/+6
Make sure the queue structs exist before trying to tear them down to make for safer error recovery. Fixes: 0f3154e6bcb3 ("ionic: Add Tx and Rx handling") Signed-off-by: Shannon Nelson <snelson@pensando.io> Signed-off-by: David S. Miller <davem@davemloft.net>
2020-03-21ionic: leave dev cmd request contents alone on FW timeoutShannon Nelson1-1/+4
It is possible (but unlikely) that FW was busy and missed a heartbeat check but is still alive and will process the pending request, so don't clean the dev_cmd in this case. This occasionally occurs when working with a card that is supporting many devices and is trying to shut them all down at once, but still wants to see that last LIF disable request.

2020-01-07ionic: clear compiler warning on hb use before setShannon Nelson1-1/+1
Build checks have pointed out that 'hb' can theoretically be used before set, so let's initialize it and get rid of the compiler complaint. Signed-off-by: Shannon Nelson <snelson@pensando.io> Signed-off-by: David S. Miller <davem@davemloft.net>
2020-01-05ionic: support sr-iov operationsShannon Nelson1-0/+4
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 <snelson@pensando.io> Signed-off-by: David S.

2019-11-02Merge git://git.kernel.org/pub/scm/linux/kernel/git/netdev/netDavid S. Miller1-0/+2
The only slightly tricky merge conflict was the netdevsim because the mutex locking fix overlapped a lot of driver reload reorganization. The rest were (relatively) trivial in nature. Signed-off-by: David S. Miller <davem@davemloft.net>
2019-10-25ionic: add heartbeat checkShannon Nelson1-1/+23
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 <snelson@pensando.io> Signed-off-by: David S. Miller <davem@davemloft.net>
2019-10-22dynamic_debug: provide dynamic_hex_dump stubArnd Bergmann1-0/+2
The ionic driver started using dymamic_hex_dump(), but that is not always defined: drivers/net/ethernet/pensando/ionic/ionic_main.c:229:2: error: implicit declaration of function 'dynamic_hex_dump' [-Werror,-Wimplicit-function-declaration] Add a dummy implementation to use when CONFIG_DYNAMIC_DEBUG is disabled, printing nothing.

2019-09-05ionic: Add basic adminq supportShannon Nelson1-0/+26
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 <snelson@pensando.io> Signed-off-by: David S.

2019-09-05ionic: Add basic lif supportShannon Nelson1-0/+1
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 <snelson@pensando.io> Signed-off-by: David S. Miller <davem@davemloft.net>
2019-09-05ionic: Add port management commandsShannon Nelson1-0/+88
