Driver reads values via HSI splitting this 8-byte into 2 32-bit values and builds a single u64 field - but it does so by shifting the lower field instead of the higher.

2017-06-01mlxsw: spectrum: Implement the ethtool flash_device callbackYotam Gigi1-9/+42
Add callback to the ethtool flash_device op. This callback uses the mlxfw module to flash the new firmware file to the device. As the firmware flash process takes about 20 seconds and ethtool takes the rtnl lock during the flash_device callback, release the rtnl lock at the beginning of the flash process and take it again before leaving the callback. This way, the rtnl is not held during the process. To make sure the device does not get deleted during the flash process, take a reference to it before releasing the rtnl lock.

2017-06-01qed: No need to reset SBs on IOV initMintz, Yuval3-33/+4
Since we're resetting the IGU CAM each time we initialize the PF device, there's no need to reset the VF SBs again when initializing IOV. Signed-off-by: Yuval Mintz <Yuval.Mintz@cavium.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2017-06-01qed: Reset IGU CAM to default on initMintz, Yuval3-20/+162
The IGU CAM contains an assocaition between hardware SBs and interrupt lines, and it can be dynamically configured to allow more interrupts in one entity over another, specifically for Re-distibution of SBs between a PF and its child VFs. While we don't yet use this functionality, there are other clients that do and as such its possible the information passed from management firmware during initialization in regard to the possible number of SBs doesn't accurately reflect the current HW configuration. The following changes are going to apply to the driver init sequence: a. PF is going to re-configure all entries belonging to itself and its child VFs in IGU CAM based on the management firmware info regarding the number of SBs that are supposed to exist there. b. PF is going to stop using the SB resource [management firmware provided information] for anything but the initialization. Instead, it would use the live-time counters it maintains for the numbers.

2017-06-01qed: Hold a single array for SBsMintz, Yuval8-27/+103
A PF today holds 2 different arrays - one holding information about the HW configuration and one holding information about the SBs that are used by the protocol drivers. These arrays aren't really connected - e.g., protocol driver initializing a given SB would not mark the same SB as occupied in the HW shadow array. Move into a single array [at least for PFs] - hold the mapping of the driver-protocol SBs on the HW entry which they configure.

2017-06-01qed: Remove assumption on SB order in IGUMintz, Yuval2-61/+33
Current code assumes there's a known layout for SBs in the IGU, where all the SBs of a single entity would be laid in consecutive order of vectors. While the assumption is still kept by management firmware, we already have the necessary information to eliminate it, so no reason to keep it in code.

2017-06-01qed: Distinguish between sb_id and igu_sb_idMintz, Yuval3-25/+30
In qed code, sb_id means 2 different things: - An interrupt vector [usually when received as a parameter from a protocol driver, but not only] that's associated with a status block. - An index to a status block entity existing in HW.

Scott enables support for TSO & GSO for MPLS encapsulated packets for both ixgbe and ixgbevf. Liwei Song fixes an issue where seqcount/seqlock in ixgbe_get_stats64() are not initialized in time, so move the initialization into probe routine after the transmit and receive rings are initialized. Paul cleans up led_[on|off] for X550EM_X, since the firmware configures the PHY & MAC and we have no PHY access so LED on/off is not supported with this device. Emil provides several fixes, starting with enabling RSS on VF to VF traffic on the same PF. Fixed PHY identification, where the previous method was unreliable, so use a different register to ensure proper identification. Cleaned up the logic which could cause us to skip the link configuration, this skipping over the link configuration was leaving SFP+ PHY's in an unstable state, so always call setup_mac_link(). Added RS1 (rate select 1) support for ixgbe. Lastly, fixed incorrect logic in the setting up of SFP+ link speed. Mark fixes the thermal sensor event logic, where it was being executed when there really was no thermal event. So simplify the logic to only execute when there is a thermal event. Tony adds additional error checks and reporting when setting a VF MAC address to ensure that the MAC filter was successfully added. Also fixed possible truncation warnings, as well as implicit fallthrough warnings. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/next-queue Jeff Kirsher says: ==================== 40GbE Intel Wired LAN Driver Updates 2017-05-31 This series contains updates to i40e and i40evf only. Jesse provides a couple of fixes, starting with cleaning up duplicate lines of code. Fixed a missing line which enables RSS as a negotiated feature. Since the VF does not have any way of reporting FCoE enabled, so just force the code to always report FCoE as disabled. Jake provides several fixes and changes, starting with fixing a race condition in i40e. The hardware has a limitation on transmit PTP packets, which requires us to limit the driver to timestamping a single packet at once. This is done using a state bitlock which enforces that only one timestamp request is honored at a time, unfortunately this suffers from a race condition. Fixed a corner case where we failed to cleanup the bit lock after a failed transmit, and resulted in a state bit being locked forever. Added a new statistic which tracks when a transmit timestamp request is skipped/ignored, since the driver can only handle one transmit timestamp request at a time. Christophe Jaillet fixes a NULL pointer dereference if kzalloc fails. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

The following warning is now shown as a result of new checks added for gcc 7: drivers/net/ethernet/intel/ixgbe/ixgbe_main.c: In function ‘ixgbe_open’: drivers/net/ethernet/intel/ixgbe/ixgbe_main.c:3118:13: warning: ‘%d’ directive output may be truncated writing between 1 and 10 bytes into a region of size between 3 and 18 [-Wformat-truncation=] "%s-%s-%d", netdev->name, "TxRx", ri++); ^~ drivers/net/ethernet/intel/ixgbe/ixgbe_main.c:3118:6: note: directive argument in the range [0, 2147483647] "%s-%s-%d", netdev->name, "TxRx", ri++); ^~~~~~~~~~ drivers/net/ethernet/intel/ixgbe/ixgbe_main.c:3117:4: note: ‘snprintf’ output between 8 and 32 bytes into a destination of size 24 snprintf(q_vector->name, sizeof(q_vector->name) - 1, ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ "%s-%s-%d", netdev->name, "TxRx", ri++); ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Resolve this warning by making a couple of changes. - Don't reserve space for the null terminator. Since snprintf adds the null terminator automatically, there is no need for us to reserve a byte for it. - Change a couple variables that can never be negative from int to unsigned int. While we're making changes to the format string, move the constant strings into the format string instead of providing them as specifiers.

2017-05-31ixgbe: Add error checking to setting VF MACTony Nguyen1-13/+41
Currently, when setting a VF MAC address there are no error checks to ensure that the MAC filter was successfully added. This patch adds additional error checks, reporting, and propagation of errors. It also will not set the MAC address unless adding the MAC filter was successful. With these changes, setting the mac address to zeros can no longer call ixgbe_set_vf_mac() as adding a zero MAC address filter is not valid. Instead directly delete the filter and, if successful, clear the MAC address.

2017-05-31ixgbe: Correct thermal sensor event checkMark Rustad1-2/+1
The thermal sensor event logic is messed up, because it can execute the code when there is no thermal event. The current logic is that it will exit when !capable && !event whereas it really should exit when !capable || !event. For one thing, it means that the service task is doing too much work. It probably has some other symptoms as well. So, correct the logic, simplifying to only execute when there is a thermal event. The capable check is redundant.
