2016-02-17i40e: count allocation errorsJesse Brandeburg1-0/+2
Driver already counted allocation errors, so print them as part of the ethtool -S output. Useful for debugging if your system is having trouble making memory available for the driver.

2016-02-16i40e: add counter for arq overflowsMitch Williams1-0/+1
Sometimes, ARQ overflows are a big deal and tell us that the firmware/hardware/driver/something is having problems. But normally they're no big deal. To assist in assessing this, add a counter to our Ethtool stats. A handful of ARQ overflows during VF init is no problem. A large, ever-growing number indicates that Something Bad is happening.

2016-02-03i40e/i40evf: Fix RSS rx-flow-hash configuration through ethtoolAnjali Singhai Jain1-10/+4
This patch fixes the Hash PCTYPE enable for X722 since it supports a broader selection of PCTYPES for TCP and UDP. This patch also fixes a bug in XL710, X710, X722 support for RSS, as of now we cannot reduce the (4)tuple for RSS for TCP/IPv4/IPV6 or UDP/IPv4/IPv6 packets since this requires a product feature change that comes in a later release. A VF should never be allowed to change the tuples for RSS for any PCTYPE since that's a global setting for the device in case of i40e devices.

2015-12-03i40e: use priv flags to control packet splitJesse Brandeburg1-0/+27
Ethtool priv flags implementation to enable or disable packet split, which is a hardware feature that inspects headers and will put headers in a separate DMA buffer from the payload data. The driver was automatically choosing to enable packet split in some cases and this gives the user the ability to turn it off/on explicitly. to query state: ethtool --show-priv-flags ethx to enable: ethtool --set-priv-flags ethx packet-split on to disable: ethtool --set-priv-flags ethx packet-split off Why would anyone want this? Because some environments benefit from header/data split in the receive buffer, and the driver defaults to one or the other depending on environment/kernel parameters. Why didn't you implement a generic ethtool control for this feature? Because Intel hardware is the only hardware that supports header/data split.

2015-10-16i40e/i40evf: moderate interrupts differentlyJesse Brandeburg1-0/+24
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.

Remove unused members in the PHY structure and add a new member to store all the capabilities the PHY has as reported by the FW. This information will help us determine what speeds the device is capable of when link is down. Also add an enum to decode the PHY types the NVM is capable of. Use the phy_types variable to determine what phy types are possible when link is down instead of device id as it will be more accurate. When on a backplane device, we do not support changing any settings, however we should display all the phy_types we are capable of so if we see a backplane dev ID set supported and advertised purely based on the phy_types variable.

Also add a new function update_link_info which updates the module_types parameter and then calls get_link_info. This function should be called in place of get_link_info so that the module_types variable stays up-to-date with the rest of the link information. The EAS table does not reflect the values that are actually returned, so instead, basing these values on the Ethernet compliance codes specified in table 33 of SFF-8436 as these have been accurate. Use the new variable in ethtool to differentiate between a 10G/1G dual speed fiber module and a 10G only module.

Previously, the driver could call this function and have only true/false returned, but false could mean multiple things like failure to read or link was down. This change allows the caller to get all return values in the call chain bubbled back to the source, which keeps information about failures from being lost. Also, in some unlikely scenarios, the firmware can become slow to respond to admin queue (AQ) queries for link state. Should the AQ time out, the driver can detect the state and avoid a link change when there may have been none.

2015-07-14i40e/i40evf: Add stats to track FD ATR and SB dynamic enable stateAnjali Singhai Jain1-0/+2
Since the driver can dynamically enable/disable FD ATR and SB features, these stats help keep track of the current state and along with fd_flush count provide a means to debug what could be going on with the flow director filters. This will take away the need for being verbose in our debug logs with respect to FD.

2015-05-28i40e: Disable offline diagnostics if VFs are enabledGreg Rose1-0/+27
Require the user to disable virtual functions before running the device offline diagnostics. The offline diagnostics are intended to ensure basic operation of the device - it is beyond the scope of the diagnostic test to handle the additional complexity of bringing all the virtual functions offline and then back online for each test run.
