Toggling the LANPHYPC Value bit cycles the power on the PHY and sets it back to power-on defaults. This includes setting it's MAC-PHY messaging mode to use the PCIe-like interconnect, so the MAC must also be set back from SMBus mode to PCIe mode otherwise the PHY can be inaccessible. Signed-off-by:

As done with the previous generation managed 82579, prevent the PHY from being put into an unknown state by blocking the hardware from automatically configuring the PHY as done with the previous generation managed 82579. Instead, the driver should configure the PHY with contents of the EEPROM image. Signed-off-by:

In rare instances, memory errors have been detected in the internal packet buffer memory on I217/I218 when stressed under certain environmental conditions. Enable Error Correcting Code (ECC) in hardware to catch both correctable and uncorrectable errors. Correctable errors will be handled by the hardware. Uncorrectable errors in the packet buffer will cause the packet to be received with an error indication in the buffer descriptor causing the packet to be discarded. If the uncorrectable error is in the descriptor itself, the hardware will stop and interrupt the driver indicating the error. The driver will then reset the hardware in order to clear the error and restart. Both types of errors will be accounted for in statistics counters. Signed-off-by:

The SHRAH[9] register on I217 has a different R/W bit-mask than RAR and SHRAL/H registers. Set R/W bit-mask appropriately for SHRAH[9] when testing the R/W ability of the register. Also, fix the error message log format so that it does not provide misleading information (i.e. the logged register address could be incorrect). Signed-off-by:

Fix a reported compilation error where ia variable of type kuid_t was being set to zero. Eliminate two instances of setting tb->fastuid to zero. tb->fastuid is only used if tb->fastreuseport is set, so there should be no problem if tb->fastuid is not initialized (when tb->fastreuesport is zero).

Pablo Neira Ayuso says: ==================== This batch contains netfilter updates for you net-next tree, they are: * The new connlabel extension for x_tables, that allows us to attach labels to each conntrack flow. The kernel implementation uses a bitmask and there's a file in user-space that maps the bits with the corresponding string for each existing label. By now, you can attach up to 128 overlapping labels. From Florian Westphal. * A new round of improvements for the netns support for conntrack. Gao feng has moved many of the initialization code of each module of the netns init path. He also made several code refactoring, that code looks cleaner to me now. * Added documentation for all possible tweaks for nf_conntrack via sysctl, from Jiri Pirko. * Cisco 7941/7945 IP phone support for our SIP conntrack helper, from Kevin Cernekee. * Missing header file in the snmp helper, from Stephen Hemminger. * Finally, a couple of fixes to resolve minor issues with these changes, from myself. ==================== Signed-off-by:

There is no actual dependency on initialization of the mailbox ops on whether SR-IOV is enabled or not and it doesn't hurt to go ahead and initialize ops unconditionally.

This change is meant to inline the Rx PTP descriptor handling. The main motivation is to avoid unnecessary jumps into function calls that we then immediately exit because we are not performing timestamps. The net result of this change is that ixgbe_ptp_rx_tstamp drops from .5% CPU utilization in my performance runs to 0%, and the only value tested is the Rx descriptor which should already be warm in the cache if not stored in a register.

This patch copies the igb implementation of Tx timestamps, which uses a work item to poll for the Tx timestamp. In addition it adds a timeout value of 15 seconds, after which it will stop polling. This is necessary due to an issue with the descriptor being marked done before the Tx timestamp event has occurred. These two events don't correlate, so using the done bit on the descriptor as indication that the timestamp must already have been taken leads to potentially dropped Tx timestamps (especially under heavy packet load) Reported-by:

This patch removes ixgbe_ptp_match, and the corresponding packet filtering from ixgbe driver. This code was previously causing some issues within the hotpath of the driver. However the code also provided a check against possible frozen Rx timestamp due to dropped packets when the Rx ring is full. This patch provides a replacement solution based on the watchdog. To this end, whenever a packet consumes the Rx timestamp it stores the jiffy value in the rx_ring structure. Watchdog updates its own jiffy timer whenever there is no valid timestamp in the registers. If watchdog detects a valid timestamp in the registers, (meaning that no Rx packet has consumed it yet) it will check which time is most recent, the last time in the watchdog, or any time in the rx_rings. If the most recent "event" was more than 5seconds ago, it will flush the Rx timestamp and print a warning message to the syslog. Reported-by:

This patch updates the filters for ethtool's get_ts_info to return support for all filters which can be supported by upscaling to ptp_v2_event. The intent behind this change is due to reasoning that we do in fact support the filters. (hwtstamp_ioctl returns success after setting the filter to the upscaled version). In this way we can remain consistent over which filters are supported via the get_ts_info ioctl and which filters are in practice actually supported. Signed-off-by:

This patch cleans up the ethtool diagnostics test by ensuring that the tests work properly regardless of what state the adapter was in. The SRIOV VF check is done at the beginning, forgoing the link test. The if_running -> dev_close is moved before the link test, as well as a call to enable the Tx laser. This ensures that the link test will return valid results even when adapter was previously down. Also, a call to disable the Tx laser is added if the device was down before the start. This ensures consistent behavior of the Tx laser before and after the diagnostic checks. The end result is consistent behavior regardless of device state. Signed-off-by:

When posting a message on the bulletin board, the PF calculates crc over the message and places the result in the message. When the VF samples the Bulletin Board it copies the message aside and validates this crc. The length of the message is crucial here and must be the same in both parties. Since the PF is running in the Hypervisor and the VF is running in a Vm, they can possibly be of different versions. As the Bulletin Board is designed to grow forward in future versions, in the VF the length must not be the size of the message structure but instead it should be a field in the message itself.

In INTA mode, cnic and bnx2x share the same IRQ. During chip reset, for example, cnic will stop servicing IRQs after it has shutdown the cnic hardware resources. However, the shared IRQ is still active as bnx2x needs to finish the reset. There is a window when bnx2x does not know that cnic is no longer handling IRQ and things don't always work properly. Add a flag to tell bnx2x that cnic is handling IRQ. The flag is set before the first cnic IRQ is expected and cleared when no more cnic IRQs are expected, so there should be no race conditions.
