git://git.kernel.org/pub/scm/linux/kernel/git/saeed/linux Saeed Mahameed says: ==================== mlx5-updates-2017-11-04 This series includes: From Huy: dscp to priority mapping for Ethernet packet. =================================================== First six patches enable differentiated services code point (dscp) to priority mapping for Ethernet packet. Once this feature is enabled, the packet is routed to the corresponding priority based on its dscp. User can combine this feature with priority flow control (pfc) feature to have priority flow control based on the dscp. Firmware interface: Mellanox firmware provides two control knobs for this feature: QPTS register allow changing the trust state between dscp and pcp mode. The default is pcp mode. Once in dscp mode, firmware will route the packet based on its dscp value if the dscp field exists. QPDPM register allow mapping a specific dscp (0 to 63) to a specific priority (0 to 7). By default, all the dscps are mapped to priority zero. Software interface: This feature is controlled via application priority TLV. IEEE specification P802.1Qcd/D2.1 defines priority selector id 5 for application priority TLV. This APP TLV selector defines DSCP to priority map. This APP TLV can be sent by the switch or can be set locally using software such as lldptool. In mlx5 drivers, we add the support for net dcb's getapp and setapp call back. Mlx5 driver only handles the selector id 5 application entry (dscp application priority application entry). If user sends multiple dscp to priority APP TLV entries on the same dscp, the last sent one will take effect. All the previous sent will be deleted. The firmware trust state (in QPTS register) is changed based on the number of dscp to priority application entries. When the first dscp to priority application entry is added by the user, the trust state is changed to dscp. When the last dscp to priority application entry is deleted by the user, the trust state is changed to pcp. When the port is in DSCP trust state, the transmit queue is selected based on the dscp of the skb. When the port is in DSCP trust state and vport inline mode is not NONE, firmware requires mlx5 driver to copy the IP header to the wqe ethernet segment inline header if the skb has it. This is done by changing the transmit queue sq's min inline mode to L3. Note that the min inline mode of sqs that belong to other features such as xdpsq, icosq are not modified. =================================================== Plus to the dscp series, some small misc changes are include as well: From Inbar, Ethtool msglvl support and some debug prints in DCBNL logic From Or Gerlitz, Enlarge the NIC TC offload table size From Rabie, Initialize destination_flow struct to 0 From Feras, Add inner TTC table to IPoIB flow steering From Tal, Enable CQE based moderation on TX CQ ==================== Signed-off-by: David S.

2017-11-05nfp: refactor nfp_app_reprs_setDirk van der Merwe
The criteria that reprs cannot be replaced with another new set of reprs has been removed. This check is not needed since the only use case that could exercise this at the moment, would be to modify the number of SRIOV VFs without first disabling them. This case is explicitly disallowed in any case and subsequent patches in this series need to be able to replace the running set of reprs. All cases where the return code used to be checked for the nfp_app_reprs_set function have been removed. As stated above, it is not possible for the current code to encounter a case where reprs exist and need to be replaced.

2017-11-05nfp: make use of MAC reinitJakub Kicinski
Recent management FW images can perform full reinit of MAC cores without requiring a reboot. When loading the driver check if there are changes pending and if so call NSP MAC reinit. Full application FW reload is still required, and all MACs need to be reinited at the same time (not only the ones which have been reconfigured, and thus potentially causing disruption to unrelated netdevs) therefore for now changing MAC config without reloading the driver still remains future work.

2017-11-05nfp: don't depend on compiler constant propagationJakub Kicinski
Matthias reports: nfp_eth_set_bit_config() is marked as __always_inline to allow gcc to identify the 'mask' parameter as known to be constant at compile time, which is required to use the FIELD_GET() macro. The forced inlining does the trick for gcc, but for kernel builds with clang it results in undefined symbols: drivers/net/ethernet/netronome/nfp/nfpcore/nfp_nsp_eth.o: In function `__nfp_eth_set_aneg': drivers/net/ethernet/netronome/nfp/nfpcore/nfp_nsp_eth.c:(.text+0x787): undefined reference to `__compiletime_assert_492' drivers/net/ethernet/netronome/nfp/nfpcore/nfp_nsp_eth.c:(.text+0x7b1): undefined reference to `__compiletime_assert_496' These __compiletime_assert_xyx() calls would have been optimized away if the compiler had seen 'mask' as a constant.

2017-11-05nfp: bpf: move to new BPF program offload infrastructureJakub Kicinski
Following steps are taken in the driver to offload an XDP program: XDP_SETUP_PROG: * prepare: - allocate program state; - run verifier (bpf_analyzer()); - run translation; * load: - stop old program if needed; - load program; - enable BPF if not enabled; * clean up: - free program image. With new infrastructure the flow will look like this: BPF_OFFLOAD_VERIFIER_PREP: - allocate program state; BPF_OFFLOAD_TRANSLATE: - run translation; XDP_SETUP_PROG: - stop old program if needed; - load program; - enable BPF if not enabled; BPF_OFFLOAD_DESTROY: - free program image. Take advantage of the new infrastructure. Allocation of driver metadata has to be moved from jit.c to offload.c since it's now done at a different stage. Since there is no separate driver private data for verification step, move temporary nfp_meta pointer into nfp_prog. We will now use user space context offsets.

2017-11-04net/mlx5e: Enable CQE based moderation on TX CQTal Gilboa
By using CQE based moderation on TX CQ we can reduce the number of TX interrupt rate. Besides the benefit of less interrupts, this also allows the kernel to better utilize TSO. Since TSO has some CPU overhead, it might not aggregate when CPU is under high stress. By reducing the interrupt rate and the CPU utilization, we can get better aggregation and better overall throughput. The feature is enabled by default and has a private flag in ethtool for control.

If the port is in DSCP trust state, packets are placed in the right priority queue based on the dscp value. This is done by selecting the transmit queue based on the dscp of the skb. Until now select_queue honors priority only from the vlan header. However that is not sufficient in cases where port trust state is DSCP mode as packet might not even contain vlan header. Therefore if the port is in dscp trust state and vport's min inline mode is not NONE, copy the IP header to the eseg's inline header if the skb has it. This is done by changing the transmit queue sq's min inline mode to L3. Note that the min inline mode of sqs that belong to other features such as xdpsq, icosq are not modified.

2017-11-04mlxsw: spectrum_router: Handle down of tunnel underlayPetr Machata
When the bound device of a tunnel device is down, encapsulated packets are not egressed anymore, but tunnel decap still works. Extend mlxsw_sp_nexthop_rif_update() to take IFF_UP into consideration when deciding whether a given next hop should be offloaded. Because the new logic was added to mlxsw_sp_nexthop_rif_update(), this fixes the case where a newly-added tunnel has a down bound device, which would previously be fully offloaded. Now the down state of the bound device is noted and next hops forwarding to such tunnel are not offloaded. In addition to that, notice NETDEV_UP and NETDEV_DOWN of a bound device to force refresh of tunnel encap route offloads.

2017-11-04mlxsw: spectrum: Handle NETDEV_CHANGE on L3 tunnelsPetr Machata
Changes to L3 tunnel netdevices (through `ip tunnel change' as well as `ip link set') lead to NETDEV_CHANGE being generated on the tunnel device. Because what is relevant for the tunnel in question depends on the tunnel type, handling of the event is dispatched to the IPIP module through a newly-added interface mlxsw_sp_ipip_ops.ol_netdev_change(). IPIP tunnels now remember the last set of tunnel parameters in struct mlxsw_sp_ipip_entry.parms, and use it to figure out what exactly has changed.
