This patch fixes a problem where the driver output of the OEM version string varied from the other tools. The mask value and the order of operations were incorrect, per the original change request.

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.

On some devices, in some systems, in some configurations, the VFs would fail to initialize the first time you loaded the driver. To correct this, increase the delay time for the init task slightly, and wait longer before giving up. If we enable VFs and load the VF driver in the same kernel as the PF driver, we can totally overwhelm the PF driver with AQ requests because all of the instances try to initialize at the same time. To help alleviate this, stagger the initial scheduling of the init task using the PCIe function as a multiplier. We mask off the function to only three bits so no instance has to wait too long. With these two changes, initializing 128 VFs on a single device goes from four minutes to just a few seconds.

The vlan_features field was correctly being set to the same value as the netdev features field. However, this was being done before the features were actually being set up, leaving the vlan_features empty. Also, after a reset, vlan_features will be incorrectly assigned the previous netdev feature flags, which can contain VLAN feature bits. This makes the VLAN code angry and will cause a stack dump. To fix these issues, set up the netdev features first, then mask out the VLAN feature bits when assigning vlan_features.

When the number of invalid messages from a VF is exceeded, the VF will be disabled, due to the invalid messages. 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.

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.

Allow the nvmupdate application to decide when a read or write error should be exposed to the user. 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.

The code in i40e and i40evf is using an "IN_NETPOLL" flag that has never added any value due to the fact that the Rx clean-up is handled in NAPI. As such the flag was set, the queue was scheduled via NAPI, and then polled from the netpoll controller and if any Rx packets were processed the were processed in the wrong context. In addition the flag itself just added an unneeded conditional to the hot-path so it can safely be dropped and save us a few instructions.
