Driver for IBM System i/p VNIC protocol This is a new device driver for a high performance SR-IOV assisted virtual network for IBM System p and IBM System i systems. The SR-IOV VF will be attached to the VIOS partition and mapped to the Linux client via the hypervisor's VNIC protocol that this driver implements. This driver is able to perform basic tx and rx, new features and improvements will be added as they are being developed and tested.

ibmvnic: Fix overflowing firmware/hardware TX queue Use a counter to track the number of outstanding transmissions sent that have not received completions. If the counter reaches the maximum number of queue entries, stop transmissions on that queue. As we receive more completions from firmware, wake the queue once the counter reaches an acceptable level. This patch prevents hardware/firmware TX queue from filling up and and generating errors. Since incorporating this fix, internal testing has reported that these firmware errors have stopped. Signed-off-by: Thomas Falcon <tlfalcon@linux.vnet.ibm.com> Signed-off-by: David S.

Since the interrupt can be triggered before all responses are written and visible to the partition, there is a danger that the interrupt handler or tasklet can terminate before all responses are read, resulting in a failure to initialize the device. To avoid this scenario, when capability commands are sent, we set a flag that will be checked in the following interrupt tasklet that will handle the capability responses from the server. Once all responses have been handled, the flag is disabled; and the tasklet is allowed to terminate. Signed-off-by: Thomas Falcon <tlfalcon@linux.vnet.ibm.com> Signed-off-by: David S.

ibmvnic: Enable use of multiple tx/rx scrqs Enables the use of multiple transmit and receive scrqs allowing the ibmvnic driver to take advantage of multiqueue functionality. To achieve this, the driver must implement the process of negotiating the maximum number of queues allowed by the server. Initially, the driver will attempt to login with the maximum number of tx and rx queues supported by the server. If the server fails to allocate the requested number of scrqs, it will return partial success in the login response. In this case, we must reinitiate the login process from the request capabilities stage and attempt to login requesting fewer scrqs.

ibmvnic: Insert header on VLAN tagged received frame This patch addresses a modification in the PAPR+ specification which now defines a previously reserved value for vNIC capabilities. It indicates whether the system firmware performs a VLAN header stripping on all VLAN tagged received frames, in case it does, the behavior expected is for the ibmvnic driver to be responsible for inserting the VLAN header.

Driver for IBM System i/p VNIC protocol This is a new device driver for a high performance SR-IOV assisted virtual network for IBM System p and IBM System i systems. The SR-IOV VF will be attached to the VIOS partition and mapped to the Linux client via the hypervisor's VNIC protocol that this driver implements. This driver is able to perform basic tx and rx, new features and improvements will be added as they are being developed and tested.

ibmvnic: Fix passive VNIC server login process In some cases, if there is no VNIC server available during the driver probe, the driver should wait until it receives an initialization request from the VNIC Server to start the login process. Recent testing has show that this is incorrectly handled in the current driver. The proposed solution handles this initialization request by scheduling a task in the shared workqueue that completes the login process and registers the net device.

ibmvnic: Handle processing of CRQ messages in a tasklet Create a tasklet to process queued commands or messages received from firmware instead of processing them in the interrupt handler. Note that this handler does not process network traffic, but communications related to resource allocation and device settings.

ibmvnic: Updated reset handling The ibmvnic driver has multiple handlers for resetting the driver depending on the reason the reset is needed (failover, lpm, fatal erors,...). All of the reset handlers do essentially the same thing, this patch moves this work to a common reset handler. By doing this we also allow the driver to better handle situations where we can get a reset while handling a reset. The updated reset handling works by adding a reset work item to the list of resets and then scheduling work to perform the reset. This step is necessary because we can receive a reset in interrupt context and we want to handle the reset out of interrupt context.
