It's common practice to store MAC addresses for network interfaces into nvmem devices. However the code to actually do this in the kernel lacks, so this patch adds of_get_nvmem_mac_address() for drivers to obtain the address from an nvmem cell provider. This is particulary useful on devices where the ethernet interface cannot be configured by the bootloader, for example because it's in an FPGA. Signed-off-by:

John Hurley authored
Trigger a port mod message to request an MTU change on the NIC when any physical port representor is assigned a new MTU value. The driver waits 10 msec for an ack that the FW has set the MTU. If no ack is received the request is rejected and an appropriate warning flagged. Rather than maintain an MTU queue per repr, one is maintained per app. Because the MTU ndo is protected by the rtnl lock, there can never be contention here. Portmod messages from the NIC are also protected by rtnl so we first check if the portmod is an ack and, if so, handle outside rtnl and the cmsg work queue. Acks are detected by the marking of a bit in a portmod response. They are then verfied by checking the port number and MTU value expected by the app. If the expected MTU is 0 then no acks are currently expected. Also, ensure that the packet headroom reserved by the flower firmware is considered when accepting an MTU change on any repr. Signed-off-by:

Rename the 'change_mtu' app callback to 'check_mtu'. This is called whenever an MTU change is requested on a netdev. It can reject the change but is not responsible for implementing it. Introduce a new 'repr_change_mtu' app callback that is hit when the MTU of a repr is to be changed. This is responsible for performing the MTU change and verifying it. Signed-off-by:

In preparation for having DSA transition entirely to PHYLINK, we need to pass a PHY interface type to the mac_link_{up,down} callbacks because we may have to make decisions on that (e.g: turn on/off RGMII interfaces etc.). We do not pass an entire phylink_link_state because not all parameters (pause, duplex etc.) are defined when the link is down, only link and interface are. Update mvneta accordingly since it currently implements phylink_mac_ops. Acked-by: -

Florian Fainelli says: ==================== net: Broadcom drivers coalescing fixes Following Tal's review of the adaptive RX/TX coalescing feature added to the SYSTEMPORT and GENET driver a number of things showed up: - adaptive TX coalescing is not actually a good idea with the current way the estimator will program the ring, this results in a higher CPU load, NAPI on TX already does a reasonably good job at maintaining the interrupt count low - both SYSTEMPORT and GENET would suffer from the same issues while configuring coalescing parameters where the values would just not be applied correctly based on user settings, so we fix that too Tal, thanks again for your feedback, I would appreciate if you could review that the new behavior appears to be implemented correctly. Thanks! Changes in v2: - added Tal's reviewed-by to the first patch - split DIM initialization from coalescing parameters initialization - avoid duplicating the same code in bcmgenet_set_coalesce() when configuring RX rings - fixed the condition where default DIM parameters would be applied when adaptive RX coalescing would be enabled, do this only if it was disabled before ==================== Signed-off-by: -

There were a number of issues with setting the RX coalescing parameters: - we would not be preserving values that would have been configured across close/open calls, instead we would always reset to no timeout and 1 interrupt per packet, this would also prevent DIM from setting its default usec/pkts values - when adaptive RX would be turned on, we woud not be fetching the default parameters, we would stay with no timeout/1 packet per interrupt until the estimator kicks in and changes that - finally disabling adaptive RX coalescing while providing parameters would not be honored, and we would stay with whatever DIM had previously determined instead of the user requested parameters Fixes: 9f4ca058 ("net: bcmgenet: Add support for adaptive RX coalescing") Signed-off-by:

NETIF_F_HW_VLAN_[CS]TAG_FILTER features require more than just a bit flip in dev->features in order to keep the driver in a consistent state. These features notify the driver of each added/removed vlan, but toggling of vlan-filter does not notify the driver accordingly for each of the existing vlans. This patch implements a similar solution to NETIF_F_RX_UDP_TUNNEL_PORT behavior (which notifies the driver about UDP ports in the same manner that vids are reported). Each toggling of the features propagates to the 8021q module, which iterates over the vlans and call add/kill ndo accordingly. Signed-off-by:

During heavy tx traffic, control messages (sent by liquidio driver to NIC firmware) sometimes do not get processed in a timely manner. Reason is: the low-level metadata of control messages and that of egress network packets indicate that they have the same priority. Fix it by setting a higher priority for control messages through the new ctrl_qpg field in the oct_txpciq struct. It is the NIC firmware that does the actual setting of priority by writing to the new ctrl_qpg field; the host driver treats that value as opaque and just assigns it to pki_ih3->qpg Signed-off-by:

David Ahern says: ==================== net: Allow FIB notifiers to fail add and replace I wanted to revisit how resource overload is handled for hardware offload of FIB entries and rules. At the moment, the in-kernel fib notifier can tell a driver about a route or rule add, replace, and delete, but the notifier can not affect the action. Specifically, in the case of mlxsw if a route or rule add is going to overflow the ASIC resources the only recourse is to abort hardware offload. Aborting offload is akin to taking down the switch as the path from data plane to the control plane simply can not support the traffic bandwidth of the front panel ports. Further, the current state of FIB notifiers is inconsistent with other resources where a driver can affect a user request - e.g., enslavement of a port into a bridge or a VRF. As a result of the work done over the past 3+ years, I believe we are at a point where we can bring consistency to the stack and offloads, and reliably allow the FIB notifiers to fail a request, pushing an error along with a suitable error message back to the user. Rather than aborting offload when the switch is out of resources, userspace is simply prevented from adding more routes and has a clear indication of why. This set does not resolve the corner case where rules or routes not supported by the device are installed prior to the driver getting loaded and registering for FIB notifications. In that case, hardware offload has not been established and it can refuse to offload anything, sending errors back to userspace via extack. Since conceptually the driver owns the netdevices associated with its asic, this corner case mainly applies to unsupported rules and any races during the bringup phase. Patch 1 fixes call_fib_notifiers to extract the errno from the encoded response from handlers. Patches 2-5 allow the call to call_fib_notifiers to fail the add or replace of a route or rule. Patch 6 adds a simple resource controller to netdevsim to illustrate how a FIB resource controller can limit the number of route entries. Changes since RFC - correct return code for call_fib_notifier - dropped patch 6 exporting devlink symbols - limited example resource controller to init_net only - updated Kconfig for netdevsim to use MAY_USE_DEVLINK - updated cover letter regarding startup case noted by Ido ==================== Signed-off-by: -

Add devlink support to netdevsim and use it to implement a simple, profile based resource controller. Only one controller is needed per namespace, so the first netdevsim netdevice in a namespace registers with devlink. If that device is deleted, the resource settings are deleted. The resource controller allows a user to limit the number of IPv4 and IPv6 FIB entries and FIB rules. The resource paths are: /IPv4 /IPv4/fib /IPv4/fib-rules /IPv6 /IPv6/fib /IPv6/fib-rules The IPv4 and IPv6 top level resources are unlimited in size and can not be changed. From there, the number of FIB entries and FIB rule entries are unlimited by default. A user can specify a limit for the fib and fib-rules resources: $ devlink resource set netdevsim/netdevsim0 path /IPv4/fib size 96 $ devlink resource set netdevsim/netdevsim0 path /IPv4/fib-rules size 16 $ devlink resource set netdevsim/netdevsim0 path /IPv6/fib size 64 $ devlink resource set netdevsim/netdevsim0 path /IPv6/fib-rules size 16 $ devlink dev reload netdevsim/netdevsim0 such that the number of rules or routes is limited (96 ipv4 routes in the example above): $ for n in $(seq 1 32); do ip ro add 10.99.$n.0/24 dev eth1; done Error: netdevsim: Exceeded number of supported fib entries. $ devlink resource show netdevsim/netdevsim0 netdevsim/netdevsim0: name IPv4 size unlimited unit entry size_min 0 size_max unlimited size_gran 1 dpipe_tables non resources: name fib size 96 occ 96 unit entry size_min 0 size_max unlimited size_gran 1 dpipe_tables ... With this template in place for resource management, it is fairly trivial to extend and shows one way to implement a simple counter based resource controller typical of network profiles. Currently, devlink only supports initial namespace. Code is in place to adapt netdevsim to a per namespace controller once the network namespace issues are resolved.
