Add the SET_VPORT_QOS device command, which is ntended for virtual granular QoS configuration per VF in SRIOV mode. The SET_VPORT_QOS command sets and queries QoS parameters of a VPort. Each priority allowed for a VPort is assigned with a share of the BW, and a BW limitation. QoS parameters can be modified at any time, but must be initialized before any QP is associated with the VPort. Signed-off-by:

Implements device ALLOCATE_VPP command, to be used for granular QoS configuration of VFs by the PF device. Defines and queries the amount of VPPs assigned to each port, and the amount of VPPs assigned to each priority of each port. Once the total VPPs are split between the priorities of a port, they may be assigned with a share of the BW or a rate limit. Split into two functions (get/set) whoch are supplied with mlx4_alloc_vpp_context and physical port number. Signed-off-by:

Create two new files fw_qos.h and fw_qos.c in mlx4_core module. It gathers all relevant QoS firmware related commands etc, thus improving encapsulation of the mlx4_core module. For now it contains the QoS existing commands: mlx4_SET_PORT_SCHEDULER and mlx4_SET_PORT_PRIO2TC. Signed-off-by:

Previous vf_oper and vf_admin code created very long lines, making it hard to read the code. Added relevant in-struct pointers to reduce code complexity and avoid code lines spread over 80 lines. Same logic is preserved. Signed-off-by:

Currently any change of netdev features results in a call to mlx4_en_update_loopback_state(). Those calls are unnecessary, and should be called only upon loopback feature change. Also moved some of the logic into mlx4_en_update_loopback_state(). Signed-off-by:

Enable RSS support for fragmented IP packets, when device supports it. Until now, fragmented IP packets were directed only to the default_qpn. Since IP fragments (datagram) have no upper protocols (L3 IP packets), hash is performed on 3-tuple - dst MAC, source IP and dest IP. The HW makes sure that this holds for the 1st fragment too, so all fragments go to the same QP. Signed-off-by:

In 'net' we added a READ_ONCE() to the socket cached RX route read, whilst in 'net-next' Eric Dumazet touched the surrounding code dealing with how mini sockets are handled. With USB, it's a case of the same bug fix first going into net-next and then I cherry picked it back into net. Signed-off-by: -

Nicolas Dichtel says: ==================== Remove iflink field from the net_device structure The first goal of this series was to advertise the veth peer via the IFLA_LINK attribute, but iflink was not ready for network namespaces. The iflink of an interface should be set to its ifindex for a physical interface and to another value (0 if not relevant) for a virtual interface. This was not the case for some interfaces, like vxlan, bond, or bridge for example. There is also a risk, if the targeted interface moves to another netns, that the ifindex changes without updating corresponding iflink fields (eg. vlan). Moving the management of this property into virtual interface drivers allows to better handle this last case because most of virtual interface drivers have a pointer to the link netdevice. Anyway, dev->iflink value was always a copy of some internal data of the virtual interface driver, thus let's use these internal data directly. So, this series removes the iflink field and let the drivers manage it. Only the last patch was present in the v1, but I fully rework it. ==================== Signed-off-by: -

Now that the peer netns is advertised in rtnl messages, we can set this property so that IFLA_LINK will advertise the peer ifindex. It allows the userland to get the full veth configuration. Signed-off-by:

Virtual interfaces are supposed to set an iflink value != of their ifindex. It was not the case for some of them, like vxlan, bond or bridge. Let's set iflink to 0 when dev->rtnl_link_ops is set. Signed-off-by:

Now that all users of iflink have the ndo_get_iflink handler available, it's possible to remove this field. By default, dev_get_iflink() returns the ifindex of the interface. Signed-off-by:

The goal of this patch is to prepare the removal of the iflink field. It introduces a new ndo function, which will be implemented by virtual interfaces. There is no functional change into this patch. All readers of iflink field now call dev_get_iflink(). Signed-off-by:

Andrew Lunn says: ==================== DSA Mavell drivers refactoring and cleanup v1->v2: * Add missing signed-of-by: For patches authored by Guenter Roeck. * Add Reviewed by from Guenter Roack to patch #5. This is a collection of patches again net-next from today containing refactoring and consolidate of code, cleanups and using #define's to replace register numbers. Patch #1 Swaps the 6131 driver to use the consolidated setup code. Patch #2 Moves the Switch IDs used during probe into a central location. We need these later so that we can differentiate the different features the devices have. Patch #3 Makes the 6131 driver set the number of ports in the private state structure. It then uses this, rather than hard coded maximum number of ports. Patch #4 Similar to Patch #3, but for the 6123_61_65 driver. Patch #5 Similar to Patch #3, and #4, but for all the remaining drivers. This greatly increases the similarity of the code between drivers, allow further patches to consolidate the duplicated code. Patch #6 Consolidate the switch reset code, which has two minor variants. Removes around 35 lines per driver. Patch #7 Moves phy page access functions out of the 6352 driver into the shared code. Currently only the 6352 driver uses this, but it is likely other devices will come along wanting this functionality. Patch #8 Consolidates the code used to access phy registers. Removes around 40 lines of code per driver. Patch #9 Fixes missing mutex locking in the EEE code, and refactors the code a bit to make it more understandable with respect to locks. Patch #10 Consolidates reading statistics. This is very similar code for all devices, but the number of available statistics differ, which can be determined from the product ID. Removes around 65 lines per driver. Patch #11 Add #defines for registers, and bits within the registers. For the moment, this is limited to the shared code. The individual drivers will be converted once the remaining duplicated code is consolidated Patch #12 Fix broken statistic counters on the 6172. The 6352 family requires the port number is poked into a different set of bits in the register compared to other devices. Many thanks to Guenter Roeck for repeatedly reviewing the patches and testing them on his hardware. ==================== Signed-off-by: -

The statistic counters for the mv88e6172 never worked. This device is a member of the 6352 family of chips, which has a slightly different layout of the register used for capturing statistics. Add support for detecting this family and poking the port in the right place in the register. Signed-off-by:
