The ability is already there in the fw and this will make it easy to toggle link without calling set_phy_config when no other link settings need to change.

This patch fixes the i40e_set_coalesce function to allow 0 as a disable value. Also, added message to user about invalid value and provides valid range.

If the firmware's API minor number is larger than the one expected, log a warning and recommend driver SW update. If the firmware's API major or minor number is smaller then the one expected (n for major, n or n-1 for minor), log a warning and recommend NVM update.

As per the spec when the PF driver receives a Malicious driver event the queue that caused the event is already stopped and it is expected that the function that owns the queue will reset the queue. In some cases it may not be possible to determine the queue and it is suggested to reset the whole function. This patch takes the later approach when the event is owned by the PF that owns it.

The return from i40e_prep_for_reset() was being ignored by almost all its callers. The one place it wasn't ignored could have caused a silent and confusing failure of the driver to finish a reset. Since we really are doing a rebuild anyway, ignore this last case as well and simply make the function a void type.

If the host VMM administrator has changed the VF device's MAC address then the i40e driver needs to halt the VF device so that the administrator will be forced to reload the VF driver. This will cause the VF driver to start using the newly assigned MAC address. This brings the i40e driver into conformance with operational characteristics of other Intel SR-IOV featured drivers.

Till now enic had been doing tx clean in isr. Using napi infrastructure to move the tx clean up out of isr to softirq. Now, wq isr schedules napi poll. In enic_poll_msix_wq we clean up the tx queus. This is applicable only on MSIX. In INTx and MSI we use single napi to clean both rx & tx queues. Signed-off-by: Govindarajulu Varadarajan <_govind@gmx.com> Signed-off-by: David S.

This patch adds support for low latency busy_poll. * Introduce drivers ndo_busy_poll function enic_busy_poll, which is called by socket waiting for data. * Introduce locking between napi_poll nad busy_poll * enic_busy_poll cleans up all the rx pkts possible. While in busy_poll, rq holds the state ENIC_POLL_STATE_POLL. While in napi_poll, rq holds the state ENIC_POLL_STATE_NAPI. * in napi_poll we return if we are in busy_poll. Incase of INTx & msix, we just service wq and return if busy_poll is going on. Signed-off-by: Govindarajulu Varadarajan <_govind@gmx.com> Signed-off-by: David S. Miller <davem@davemloft.net>

This patch adds supports for Accelerated Receive Flow Steering. When the desired rx is different from current rq, for a flow, kernel calls the driver function enic_rx_flow_steer(). enic_rx_flow_steer adds a IP-TCP/UDP hardware filter. Driver registers a timer function enic_flow_may_expire. This function is called every HZ/4 seconds. In this function we check if the added filter has expired by calling rps_may_expire_flow(). If the flow has expired, it removes the hw filter. As of now adaptor supports only IPv4 - TCP/UDP filters. Signed-off-by: Govindarajulu Varadarajan <_govind@gmx.com> Signed-off-by: David S.

rx_cpu_rmap provides the reverse irq cpu affinity. This patch allocates and sets drivers netdev->rx_cpu_rmap accordingly. rx_cpu_rmap is set in enic_request_intr() which is called by enic_open and rx_cpu_rmap is freed in enic_free_intr() which is called by enic_stop. This is used by Accelerated RFS. Signed-off-by: Govindarajulu Varadarajan <_govind@gmx.com> Signed-off-by: David S. Miller <davem@davemloft.net>

skb_flow_dissect() dissects only transport header type in ip_proto. It dose not give any information about IPv4 or IPv6. This patch adds new member, n_proto, to struct flow_keys. Which records the IP layer type. i.e IPv4 or IPv6. This can be used in netdev->ndo_rx_flow_steer driver function to dissect flow. Adding new member to flow_keys increases the struct size by around 4 bytes. This causes BUILD_BUG_ON(sizeof(qcb->data) < sz); to fail in qdisc_cb_private_validate() So increase data size by 4 Signed-off-by: Govindarajulu Varadarajan <_govind@gmx.com> Signed-off-by: David S.

Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates 2014-06-20 This series contains updates to i40e and i40evf. Anjali provides an update to the registers to handle the updates from the hardware. Also provides a fix so that we do not try to access the rings through the qvectors at the time of freeing the qvectors. Jesse provides a workaround for some older NVM versions where the NVM was not filling in the GLQF_HKEY register, so made sure that the critical register is initialized. Michal provides a fix to reset the head and tail on admin queue initialization where head and tail are not reset by the hardware. Neerav adds a helper routine that would wait for the Rx/Tx queue to reach the enable or disable state that is requested. Also provides a fix to the debugfs command "lldp get remote" which was dumping the local LLDPDU instead of the peer's LLDPDU. Fixed a bug when all the Tx hang recovery mechanisms have failed and the driver tries to bring down the interface in the interrupt context. Shannon provides a patch to clear the Virtual Ethernet Bridge (VEB) stats when the PF stats are cleared. Also cleans the service tasks so that they do not run while a reset is in progress. Mitch fixes an issue in i40evf_get_rxfh() where only fifteen registers were being read instead of all sixteen. Carolyn provides a change to the RSS configuration to set table size and write to the hardware to confirm the RSS table size being used. Kamil makes a change to the admin queue debug prints so that they will not cause segmentation faults in some of our tool applications. ==================== Signed-off-by: David S.
