2015-10-23i40e/i40evf: Add a workaround to drop all flow control framesAnjali Singhai Jain3-0/+42
This patch adds a workaround to drop any flow control frames from being transmitted from any VSI. FW can still send flow control frames if flow control is enabled. With this patch in place a malicious VF cannot send flow control or PFC packets out on the wire.

git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/next-queue Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates 2015-10-19 This series contains updates to i40e and i40evf only. Kiran adds a spinlock around code accessing VSI MAC filter list to ensure that we are synchronizing access to the filter list, otherwise we can end up with multiple accesses at the same time which can cause the VSI MAC filter list to get in an unstable or corrupted state. Jesse fixes overlong BIT defines, where the RSS enabling call were mistakenly missed. Also fixes a bug where the enable function was enabling the interrupt twice while trying to update the two interrupt throttle rate thresholds for Rx and Tx, while refactoring the IRQ enable function to simplify reading the flow. Addressed the high CPU utilization of some small streaming workloads that the driver should reduce CPU in. Anjali fixes two X722 issues with respect to EEPROM checksum verify and reading NVM version info. Fixed where a mask value was accidentally replaced with a bit mask causing Flow Director sideband to be broken. Alex Duyck fixes areas of the drivers which run from hard interrupt context or with interrupts already disabled in netpoll, so use napi_schedule_irqoff() instead of napi_schedule(). Mitch fixes the VF drivers to not easily give up when it is not able to communicate with the PF driver. Carolyn fixes a problem where our tools MAC loopback test, after driver unbind would fail because the hardware was configured for multiqueue and unbind operation did not clear this configuration. Also fixed a issue where the NVMUpdate tool gets bad data from the PHY when using the PHY NVM feature because of contention on the MDIO interface from getting PHY capability calls from the driver during regular operations. Catherine fixed an issue where we were checking if autoneg was allowed to change before checking if autoneg was changing, these checks need to be in the reverse order. Jean Sacren fixes up an function header comment to align the kernel-docs with the actual code. v2: Cleaned up the use of spin_is_locked() in patch 1 based on feedback from David Miller, since it always evaluates to zero on uni-processor builds ==================== Signed-off-by: David S.

2015-10-19i40e/i40evf: change dynamic interrupt thresholdsJesse Brandeburg2-6/+24
The dynamic algorithm, while now working, doesn't have good performance in 40G mode. One part of this patch addresses the high CPU utilization of some small streaming workloads that the driver should reduce CPU in. It also changes the minimum ITR that the dynamic algorithm will settle on, causing our minimum latency to go from 12us to about 14us, when using adaptive mode. It also changes the BULK interrupt rate to allow maximum throughput on a 40Gb connection with a single thread of transmit, clamping interrupt rate to 8000 for TX makes single thread traffic go too slow. The new ULTRA bulk setting is introduced and is used when the Rx packet rate on this queue exceeds 40000 packets per second. This value of 40000 was chosen because the automatic tuning of minimum ITR=20us means that a single queue can't quite achieve that many packets per second from a round-robin test.

With 64 VFs, we can easily overwhelm the AQ on the PF if we have too low a limit on the number of AQ requests. This leads to ARQ overflow errors, and occasionally VFs that fail to initialize. Since we really only hit this condition on initial VF driver load, the requests that we process are lightweight, so this extra work doesn't cause problems for the PF driver.

2015-10-16i40e: reset the invalid msg counter in vf when a valid msg is receivedJingjing Wu2-1/+4

This happens if other VF drivers (like DPDK) send a message through the driver's mailbox (aka virtchannel) interface, but the message is not supported by the i40e pf driver, such as CONFIG_PROMISCUOUS_MODE. This patch changes the num_invalid_msgs in struct i40e_vf to record the continuous invalid msgs, and it will be reset when a valid msg is received.

2015-10-16i40e/i40evf: moderate interrupts differentlyJesse Brandeburg4-3/+42
The XL710 hardware has a different interrupt moderation design that can support a limit of total interrupts per second per vector, in addition to the "number of interrupts per second" controls already established in the driver. This combination of hardware features allows us to set very low default latency settings but minimize the total CPU utilization by not making too many interrupts, should the user desire. The current driver implementation is still enabling the dynamic moderation in the driver, and only using the rx/tx-usecs limit in ethtool to limit the interrupt rate per second, by default. The new code implemented in this patch 2) adds init/use of the new "Interrupt Limit" register 3) adds ethtool knob to control/report the limits above Usage is ethtool -C ethx rx-usecs-high <value> Where <value> is number of microseconds to create a rate of 1/N interrupts per second, regardless of rx-usecs or tx-usecs values. Since there is a credit based scheme in the hardware, the rx-usecs and tx-usecs can be configured for very low latency for short bursts, but once the credit runs out the refill rate on the credits is limited by rx-usecs-high.

Since the application needs to use write probes to find the ReadOnly sections on a potentially unknown NVM version in the HW and read probes to check the status of the last write, some error messages are expected, but need not be shown to the users. The driver doesn't know which are ignorable from real errors, so needs to let the application make the decision.
