2017-06-09nfp: remove automatic caching of RTsym tableJakub Kicinski
The fact that RTsym table is cached inside nfp_cpp handle is a relic of old times when nfpcore was a library module. All the nfp_cpp "caches" are awkward to deal with because of concurrency and prone to keeping stale information. Make the run time symbol table be an object read out from the device and managed by whoever requested it. Since the driver loads FW at ->probe() and never reloads, we can hold onto the table for ever. Signed-off-by: Jakub Kicinski <jakub.kicinski@netronome.com> Signed-off-by: David S.

2017-06-09nfp: make sure to cancel port refresh on the error pathJakub Kicinski
If very last stages of netdev registering and init fail some other netdevs and devlink ports may have been visible to user space before we torn them back down. In this case there is a slight chance user may have triggered port refresh. We need to make sure the async work is cancelled. We have to cancel after releasing pf->lock, so we will always try to cancel, regardless of which part of probe has failed.

2017-06-09Ipvlan should return an error when an address is already in use.Krister Johansen
The ipvlan code already knows how to detect when a duplicate address is about to be assigned to an ipvlan device. However, that failure is not propogated outward and leads to a silent failure. Introduce a validation step at ip address creation time and allow device drivers to register to validate the incoming ip addresses. The ipvlan code is the first consumer. If it detects an address in use, we can return an error to the user before beginning to commit the new ifa in the networking code. This can be especially useful if it is necessary to provision many ipvlans in containers. The provisioning software (or operator) can use this to detect situations where an ip address is unexpectedly in use. Signed-off-by: Krister Johansen <kjlx@templeofstupid.com> Signed-off-by: David S.

Marvell chips have a Jumbo Mode to set the maximum frame size (MTU). The mv88e6xxx_ops structure is meant to contain generic functionalities, no driver logic. Change port_jumbo_config to port_set_jumbo_size setting the mode from a given maximum size value. There is no functional changes since we still use 10240 bytes.

2017-06-09net: dsa: mv88e6xxx: rework pause limit operationVivien Didelot
All Marvell chips supporting Pause frames limiting use 1-byte value for input and output. Old chips have both bytes adjacent in a 16-bit register. New ones have an indirect table using 8-bit data. The mv88e6xxx library functions (such as in port.c) must not contain driver logic, but only generic helpers. This patch changes the port_pause_config operation for port_pause_limit taking two u8 arguments for input and output limits. There is no functional changes.

2017-06-09net: dsa: mv888e6xxx: do not use netdev printingVivien Didelot
The mv888e6xxx driver accesses a port's netdev mostly for printing. This is bad for 2 reasons: DSA and CPU ports do not have a netdev pointer; it doesn't give us a correct picture of why a DSA driver might need to access a port's netdev. Instead simply use dev_* printing functions with chip->dev (or ds->dev depending on the scope, both guaranteed to exist), with a p%d prefix for the target port.

CAN FD capable CAN interfaces can handle (classic) CAN 2.0 frames too. New users usually fail at their first attempt to explore CAN FD on virtual CAN interfaces due to the current CAN_MTU default. Set the MTU to CANFD_MTU by default to reduce this confusion. If someone *really* needs a 'classic CAN'-only device this can be set with the 'ip' tool with e.g. 'ip link set vcan0 mtu 16' as before.

Commit 1aa6c4f6b8cd8 ("net: vrf: Add l3mdev rules on first device create") adds the l3mdev FIB rule the first time a VRF device is created. However, it only creates the rule once and only in the namespace the first device is created - which may not be init_net. Fix by using the net_generic capability to make the add_fib_rules flag per network namespace.
