2019-04-23net: phy: marvell: add new default led configure for m88e151xJian Shen3-1/+9
The default m88e151x LED configuration is 0x1177, used LED[0] for 1000M link, LED[1] for 100M link, and LED[2] for active. But for some boards, which use LED[0] for link, and LED[1] for active, prefer to be 0x1040. To be compatible with this case, this patch defines a new dev_flag, and set it before connect phy in HNS3 driver. When phy initializing, using the new LED configuration if this dev_flag is set.

The CPU port is used to transmit traffic that is trapped to the host CPU. It is therefore irrelevant to define ingress quota for it.

The function is used to set the per-port shared buffer quotas. Currently, these quotas are only set for front panel ports, but a subsequent patch will configure these quotas for the CPU port as well. The configuration required for the CPU port is a bit different than that of the front panel ports, so split the business logic into a separate function which will be called with different parameters for the CPU port.

2019-04-22mlxsw: spectrum_buffers: Use new CPU ingress pool for control packetsIdo Schimmel1-12/+7
Use the new ingress pool that was added in the previous patch for control packets (e.g., STP, LACP) that are trapped to the CPU. The previous management pool is no longer necessary and therefore its size is set to 0. The maximum quota for traffic towards the CPU is increased to 50% of the free space in the new ingress pool and therefore the reserved space is reduced by half, to 10KB - in both the shared and headroom buffer. This allows for more efficient utilization of the shared buffer as reserved space cannot be used for other purposes.

Packets that are trapped to the CPU are transmitted through the CPU port to the attached host. The CPU port is therefore like any other port and needs to have shared buffer configuration. The maximum quotas configured for the CPU are provided using dynamic threshold and cannot be changed by the user. In order to make sure that these thresholds are always valid, the configuration of the threshold type of these pools is forbidden.

Lets remove the modular code that is essentially orphaned, so that when reading the driver there is no doubt it is builtin-only.

After commit c7a1ce397ada ("ipv6: Change addrconf_f6i_alloc to use ip6_route_info_create"), the gateway is no longer filled in for fib6_nh structs in a prefix route. Accordingly, the RTF_ADDRCONF flag check can be dropped from the 'rt6_qualify_for_ecmp'. Further, RTF_DYNAMIC is only set in rt6_info instances, so it can be removed from the check as well. This reduces rt6_qualify_for_ecmp and the mlxsw version to just checking if the nexthop has a gateway which is the real indication of whether entries can be coalesced into a multipath route.

2019-04-21mlxsw: spectrum_router: Relax FIB rule validationIdo Schimmel1-0/+4
Currently, mlxsw does not support policy-based routing (PBR) and therefore forbids the installation of non-default FIB rules except for the l3mdev rule which is used for VRFs. Relax the check to allow the installation of FIB rules that would never match packets received by the device. Specifically, if the iif is that of the loopback netdev. This is useful for users that need to redirect locally generated packets based on FIB rules.

2019-04-21mlxsw: spectrum: Use a stable ECMP/LAG seedIdo Schimmel2-4/+4
In order to get a consistent behavior of traffic flows across reboots / module unload, we need to use the same ECMP/LAG seed. Calculate the seed by hashing the base MAC of the device. This results in a seed that is both unique (to avoid polarization) and consistent. Signed-off-by: Ido Schimmel <idosch@mellanox.com> Acked-by: Jiri Pirko <jiri@mellanox.com> Signed-off-by: David S.

2019-04-19nfp: add SR-IOV trusted VF supportPablo Cascón4-2/+33
By default VFs are not trusted. Add ndo_set_vf_trust support to toggle a new per-VF bit. Coupled with FW with this capability allows a trusted VF to change its MAC even after being administratively set by the PF. Also populate the trusted field on ndo_get_vf_config. Add the same ndo to the representors. Signed-off-by: Pablo Cascón <pablo.cascon@netronome.com> Reviewed-by: Jakub Kicinski <jakub.kicinski@netronome.com> Signed-off-by: David S.

2019-04-19net: hns3: Add handling of MAC tunnel interruptionWeihang Li7-0/+96
MAC tnl interruptions are different from other type of RAS and MSI-X errors, because some bits, such as OVF/LR/RF will occur during link up and down. The drivers should clear status of all MAC tnl interruption bits but shouldn't print any message that would mislead the users. In case that link down and re-up in a short time because of some reasons, we record when they occurred, and users can query them by debugfs.
