2020-03-30net: mscc: ocelot: add action of police on vcap_is2Xiaoliang Yang6-7/+100
Ocelot has 384 policers that can be allocated to ingress ports, QoS classes per port, and VCAP IS2 entries. ocelot_police.c supports to set policers which can be allocated to police action of VCAP IS2. We allocate policers from maximum pol_id, and decrease the pol_id when add a new vcap_is2 entry which is police action.

2020-03-30ionic: remove lifs on fw resetShannon Nelson5-25/+158
When the FW RESET event comes to the driver from the firmware, or the fw_status goes to 0 (stopped) or to 0xff (no PCI connection), then shut down the driver activity. This event signals a FW upgrade where we need to quiesce all operations and wait for the FW to restart. The FW will continue the update process once it sees all the LIFs are reset. When the update process is done it will set the fw_status back to RUNNING. Meanwhile, the heartbeat check continues and when the fw_status is seen as set to running we can restart the driver operations.

2020-03-30ionic: disable the queues on link downShannon Nelson1-56/+61
When the link goes down, we need to disable the queues on the NIC in addition to stopping the netdev stack. This lets the FW know that the driver has stopped queue activity, and then the FW can do internal reconfiguration work, whether actually Link related, or for other internal FW needs. To do this, we pull out the queue enable and disable from ionic_open() and ionic_stop() so they can be used by other routines. To help keep things sane, we swap the queue enables so that the rx queue and its napi are enabled before the tx queue which rides on the rx queues napi. We also drop the ionic_lif_quiesce() as it doesn't do anything more than what the queue disable has already taken care of. Signed-off-by: Shannon Nelson <snelson@pensando.io> Signed-off-by: David S.

No reason to explicitly get the auto recover flag from the driver. Remove this flag from all drivers that called devlink_health_reporter_create.

2020-03-30ptp: Avoid deadlocks in the programmable pin code.Richard Cochran4-3/+44
The PTP Hardware Clock (PHC) subsystem offers an API for configuring programmable pins. User space sets or gets the settings using ioctls, and drivers verify dialed settings via a callback. Drivers may also query pin settings by calling the ptp_find_pin() method. Although the core subsystem protects concurrent access to the pin settings, the implementation places illogical restrictions on how drivers may call ptp_find_pin(). When enabling an auxiliary function via the .enable(on=1) callback, drivers may invoke the pin finding method, but when disabling with .enable(on=0) drivers are not permitted to do so. With the exception of the mv88e6xxx, all of the PHC drivers do respect this restriction, but still the locking pattern is both confusing and unnecessary. This patch changes the locking implementation to allow PHC drivers to freely call ptp_find_pin() from their .enable() and .verify() callbacks.

2020-03-29net/mlx5: Use a separate work queue for fib event handlingMark Zhang2-4/+11
In VF lag mode when remove the bonding module without bring down the bond device first, we could potentially have circular dependency when we unload IB devices and also handle fib events: 1. The bond work starts first; 2. The "modprobe -rv bonding" process tries to release the bond device, with the "pernet_ops_rwsem" lock hold; 3. The bond work blocks in unregister_netdevice_notifier() and waits for the lock because fib event came right before; 4. The kernel fib module tries to free all the fib entries by broadcasting the "FIB_EVENT_NH_DEL" event; 5. Upon the fib event this lag_mp module holds the fib lock and queue a fib work. So: bond work -> modprobe task -> kernel fib module -> lag_mp -> bond work Today we either reload IB devices in roce lag in nic mode or either handle fib events in switchdev mode, but a new feature could change that we'll need to reload IB devices also in switchdev mode so this is a future proof fix as one may not notice this later.

This patch adds a functionality to addrconf to check on a specific RPL address configuration. According to RFC 6554: To detect loops in the SRH, a router MUST determine if the SRH includes multiple addresses assigned to any interface on that router. If such addresses appear more than once and are separated by at least one address not assigned to that router. Signed-off-by: Alexander Aring <alex.aring@gmail.com> Signed-off-by: David S.
