for non ECPF eswitch manager function, vports are already enabled/disabled when eswitch is enabled/disabled respectively. Simplify function change handler for such eswitch manager function. Therefore, ECPF is the only one which remains PF/VF function change handler. Signed-off-by:

TLS runs only over Eth, and the Eth driver is the only user of the core TLS functionality. There is no meaning of having the core functionality without the usage in Eth driver. Hence, let both TLS core implementations depend on MLX5_CORE_EN, and select MLX5_EN_TLS. Signed-off-by:

Having the users of MSCC_OCELOT_SWITCH_LIB depend on REGMAP_MMIO was a bad idea, since that symbol is not user-selectable. So we should have kept a 'select REGMAP_MMIO'. When we do that, we run into 2 more problems: - By depending on GENERIC_PHY, we are causing a recursive dependency. But it looks like GENERIC_PHY has no other dependencies, and other drivers select it, so we can select it too: drivers/of/Kconfig:69:error: recursive dependency detected! drivers/of/Kconfig:69: symbol OF_IRQ depends on IRQ_DOMAIN kernel/irq/Kconfig:68: symbol IRQ_DOMAIN is selected by REGMAP drivers/base/regmap/Kconfig:7: symbol REGMAP default is visible depending on REGMAP_MMIO drivers/base/regmap/Kconfig:39: symbol REGMAP_MMIO is selected by MSCC_OCELOT_SWITCH_LIB drivers/net/ethernet/mscc/Kconfig:15: symbol MSCC_OCELOT_SWITCH_LIB is selected by MSCC_OCELOT_SWITCH drivers/net/ethernet/mscc/Kconfig:22: symbol MSCC_OCELOT_SWITCH depends on GENERIC_PHY drivers/phy/Kconfig:8: symbol GENERIC_PHY is selected by PHY_BCM_NS_USB3 drivers/phy/broadcom/Kconfig:41: symbol PHY_BCM_NS_USB3 depends on MDIO_BUS drivers/net/phy/Kconfig:13: symbol MDIO_BUS depends on MDIO_DEVICE drivers/net/phy/Kconfig:6: symbol MDIO_DEVICE is selected by PHYLIB drivers/net/phy/Kconfig:254: symbol PHYLIB is selected by ARC_EMAC_CORE drivers/net/ethernet/arc/Kconfig:19: symbol ARC_EMAC_CORE is selected by ARC_EMAC drivers/net/ethernet/arc/Kconfig:25: symbol ARC_EMAC depends on OF_IRQ - By depending on PHYLIB, we are causing a recursive dependency.

A busy-wait loop is used to implement waiting for bits to be copied from the skb to the kernel buffer before retiring a block. This is a problem on PREEMPT_RT because the copying task could be preempted by the busy-waiting task and thus live lock in the busy-wait loop. Replace the busy-wait logic with an rwlock_t. This provides lockdep coverage and makes the code RT ready. Signed-off-by:

Sergey Organov says: ==================== net: fec: a few improvements This is a collection of simple improvements that reduce and/or simplify code. They got developed out of attempt to use DP83640 PTP PHY connected to built-in FEC (that has its own PTP support) of the iMX 6SX micro-controller. The primary bug-fix was now submitted separately, and this is the rest of the changes. NOTE: the patches are developed and tested on 4.9.146, and rebased on top of recent 'net-next/master', where, besides visual inspection, I only tested that they do compile. ==================== Signed-off-by: -

Initializing with 0 makes it much easier to identify time stamps from otherwise uninitialized clock. Initialization of PTP clock with current kernel time makes little sense as PTP time scale differs from UTC time scale that kernel time represents. It only leads to confusion when no actual PTP initialization happens, as these time scales differ in a small integer number of seconds (37 at the time of writing.) Signed-off-by:

Ido Schimmel says: ==================== mlxsw: Offload tc police action This patch set adds support for tc police action in mlxsw. Patches #1-#2 add defines for policer bandwidth limits and resource identifiers (e.g., maximum number of policers). Patch #3 adds a common policer core in mlxsw. Currently it is only used by the policy engine, but future patch sets will use it for trap policers and storm control policers. The common core allows us to share common logic between all policer types and abstract certain details from the various users in mlxsw. Patch #4 exposes the maximum number of supported policers and their current usage to user space via devlink-resource. This provides better visibility and also used for selftests purposes. Patches #5-#7 gradually add support for tc police action in the policy engine by calling into previously mentioned policer core. Patch #8 adds a generic selftest for tc-police that can be used with veth pairs or physical loopbacks. Patches #9-#11 add mlxsw-specific selftests. ==================== Signed-off-by: -

Add core functionality required to support police action in the policy engine. The utilized hardware policers are stored in a hash table keyed by the flow action index. This allows to support policer sharing between multiple ACL rules. Signed-off-by:
-
Ido Schimmel authored
In the policy engine, each ACL rule points to an action block where the ACL actions are stored. Each action block consists of one or more action sets. Each action set holds one or more individual actions, up to a maximum queried from the device. For example: Action set #1 Action set #2 +----------+ +--------------+ +--------------+ | ACL rule +----------> Action #1 | +-----> Action #4 | +----------+ +--------------+ | +--------------+ | Action #2 | | | Action #5 | +--------------+ | +--------------+ | Action #3 +------+ | | +--------------+ +--------------+ <---------+ Action block +-----------------> The hardware has a limitation that prevents a policing action (MLXSW_AFA_POLCNT_CODE when used with a policer, not a counter) from being configured in the same action set with a trap action (i.e., MLXSW_AFA_TRAP_CODE or MLXSW_AFA_TRAPWU_CODE). Note that the latter used to implement multiple actions: 'trap', 'mirred', 'drop'. Work around this limitation by teaching mlxsw_afa_block_append_action() to create a new action set not only when there is no more room left in the current set, but also when there is a conflict between previously mentioned actions.
