2016-11-25mlxsw: switchib: Use generic listener struct for eventsNogah Frankel
Change the event handling in Switchib to be comptible with Spectrum and Switchx2. Use the generic listener struct for the events. Init and fini them by loop (and not by calling each event by its name). Signed-off-by: Nogah Frankel <nogahf@mellanox.com> Signed-off-by: Jiri Pirko <jiri@mellanox.com> Signed-off-by: David S.

2016-11-25mlxsw: core: Create a generic function to register / unregister trapsNogah Frankel
We have 2 types of HW traps to handle, rx traps and events. The registration workflow for both is very similar. So it only make sense to create one function to handle both. This patch creates a struct to hold the data for both cases. It also creates a registration and an un-registration functions that get this generic struct as input.

2016-11-25mlxsw: spectrum: Remove unused trapsNogah Frankel
Since commit 99724c18fc66 ("mlxsw: spectrum: Introduce support for router interfaces") we no longer rely on flooding traffic to the CPU in order to trap packets intended for the host itself. Therefore, the FDB MC trap can be removed. Remove traps for protocols that are not supported yet.

2016-11-25mvpp2: use correct size for memsetArnd Bergmann
gcc-7 detects a short memset in mvpp2, introduced in the original merge of the driver: drivers/net/ethernet/marvell/mvpp2.c: In function 'mvpp2_cls_init': drivers/net/ethernet/marvell/mvpp2.c:3296:2: error: 'memset' used with length equal to number of elements without multiplication by element size [-Werror=memset-elt-size] The result seems to be that we write uninitialized data into the flow table registers, although we did not get any warning about that uninitialized data usage. Using sizeof() lets us initialize then entire array instead.

The report is valid: doing the math in this function, with an input value N=63 the variable s16tableIndex gets a value of 31. This value is used as an index in the array log_table with 32 entries. But the next line is: s16errorApproximation = (s16) qm_mulu16(u16offset, (u16) (log_table[s16tableIndex + 1] - log_table[s16tableIndex])); With s16tableIndex + 1 we are trying an out-of-bounds access to the array. The log_table array provides log2 values in q.15 format and the above statement tries an error approximation with the next value.

In addition it also seems prone to issues when setting REG_RF_CTRL to 0 intead of just disabling the RF_ENABLE bit. Similar to what was causing issues with the 8188eu.

2016-11-24ethtool: Protect {get, set}_phy_tunable with PHY device mutexFlorian Fainelli
PHY drivers should be able to rely on the caller of {get,set}_tunable to have acquired the PHY device mutex, in order to both serialize against concurrent calls of these functions, but also against PHY state machine changes. All ethtool PHY-level functions do this, except {get,set}_tunable, so we make them consistent here as well. We need to update the Microsemi PHY driver in the same commit to avoid introducing either deadlocks, or lack of proper locking.

Reflect the administative link changes done on the VF representor to the VF e-switch vport. This means that doing ip link set down/up commands on the VF rep will modify the e-switch vport state which in turn will make proper VF drivers to set their carrier accordingly.

2016-11-24net/mlx5e: Support HW (offloaded) and SW counters for SRIOV switchdev modeOr Gerlitz
Switchdev driver net-device port statistics should follow the model introduced in commit a5ea31f57309 'Merge branch net-offloaded-stats'. For VF reps we return the SRIOV eswitch vport stats as the usual ones and SW stats if asked. For the PF, if we're in the switchdev mode, we return the uplink stats and SW stats if asked, otherwise as before. The uplink stats are implemented using the PPCNT 802_3 counters which are already being read/cached by the driver.
