Switch the CPU port to use the new dedicated egress pool instead the previously used egress pool which was shared with normal front panel ports. Add per-port quotas for the amount of traffic that can be buffered for the CPU port and also adjust the per-{port, TC} quotas.

2019-04-22mlxsw: spectrum_buffers: Allow skipping ingress port quota configurationIdo Schimmel1-2/+8
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. Add a 'skip_ingress' argument to the function tasked with configuring per-port quotas, so that ingress quotas could be skipped in case the passed local port is the CPU port.

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.

2019-04-22mlxsw: spectrum_buffers: Add pools for CPU trafficIdo Schimmel1-0/+20
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.

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.

Anirudh fixes up code comments which had typos. Added support for DCB into the ice driver, which required a bit of refactoring of the existing code. Also fixed a potential race condition between closing and opening the VSI for a MIB change event, so resolved this by grabbing the rtnl_lock prior to closing. Added support to process LLDP MIB change notifications. Added support for reporting DCB stats via ethtool. Brett updates the calculation to increment ITR to use a direct calculation instead of using estimations. This provides a more accurate value. ==================== Signed-off-by: David S.

Major changes: iwlwifi * send NO_DATA events so they can be captured in radiotap * support for multiple BSSID * support for some new FW API versions * support new hardware * debugfs cleanups by Greg-KH qtnfmac * allow each MAC to specify its own regulatory rules ==================== Signed-off-by: David S.

2019-04-18ice: Calculate ITR increment based on direct calculationBrett Creeley1-72/+63
Currently when calculating how much to increment ITR by inside of ice_update_itr() we do some estimations and intermediate calculations. Instead of doing estimations, just do the calculation directly. This allows for a more accurate value and it makes it easier for the next person to understand and update. Also, remove the dividing the ITR value by 2 when latency driven because the ITR values are already so low for 100Gbps speed. This should help get to the desired ITR value faster.
