2020-01-19selftests: devlink_trap_l3_drops: Add test cases of irif and erif disabledAmit Cohen1-0/+112

2020-01-19mlxsw: Add irif and erif disabled trapsAmit Cohen4-0/+51
IRIF_DISABLED and ERIF_DISABLED are driver specific traps. Packets are dropped for these reasons when they need to be routed through/from existing router interfaces (RIF) which are disabled. Add devlink driver-specific traps and mlxsw trap IDs used to report these traps.

If the serdes link is set to 2500 using interfce type 2500base-X, lower link speeds over on the line side should still be supported. Rate adaptation is done out of band, in our case using AQR PHYs this is done using flow control.

2020-01-19net: dsa: felix: Handle PAUSE RX regardless of AN resultAlex Marginean1-2/+6
Flow control is used with 2500Base-X and AQR PHYs to do rate adaptation between line side 100/1000 links and MAC running at 2.5G. This is independent of the flow control configuration settled on line side though AN. In general, allowing the MAC to handle flow control even if not negotiated with the link partner should not be a problem, so the patch just enables it in all cases.

Make use of the new txqueue parameter to the .ndo_tx_timeout function. In fm10k_tx_timeout, remove the now unnecessary loop to determine which Tx queue is stuck. Instead, just double check the specified queue This could be improved further to attempt resetting only the specific queue that got stuck.

Some PHYs like VSC8234 don't like it when AN restarts on their system side and they restart line side AN too, going into an endless link up/down loop. Don't restart PCS AN if link is up already. Although in theory this feedback loop should be possible with the other in-band AN modes too, for some reason it was not seen with the VSC8514 QSGMII and AQR412 USXGMII PHYs.

We maintain global statistics for an entire MDIO bus, as well as broken down, per MDIO bus address statistics. Given that it is possible for MDIO devices such as switches to access MDIO bus addresses for which there is not a mdio_device instance created (therefore not a a corresponding device directory in sysfs either), we also maintain per-address statistics under the statistics folder. The layout looks like this: /sys/class/mdio_bus/../statistics/ transfers errrors writes reads transfers_<addr> errors_<addr> writes_<addr> reads_<addr> When a mdio_device instance is registered, a statistics/ folder is created with the tranfers, errors, writes and reads attributes which point to the appropriate MDIO bus statistics structure. Statistics are 64-bit unsigned quantities and maintained through the u64_stats_sync.h helper functions.

2020-01-16net/mlx5: fs_core: Introduce unmanaged flow tablesPaul Blakey2-12/+31
Currently, Most of the steering tree is statically declared ahead of time, with steering prios instances allocated for each fdb chain to assign max number of levels for each of them. This allows fs_core to manage the connections and levels of the flow tables hierarcy to prevent loops, but restricts us with the number of supported chains and priorities. Introduce unmananged flow tables, allowing the user to manage the flow table connections. A unamanged table is detached from the fs_core flow table hierarcy, and is only connected back to the hierarchy by explicit FTEs forward actions. This will be used together with firmware that supports ignoring the flow table levels to increase the number of supported chains and prios.
