2019-05-26net: hns3: add aRFS support for PFJian Shen4-0/+238
This patch adds aRFS support for PF. The aRFS rules are also stored in the hardware flow director table, Use the existing filter management functions to insert TCPv4/UDPv4/TCPv6/UDPv6 flow director filters. To avoid rule conflict, once user adds flow director rules with ethtool, the aRFS will be disabled, and clear exist aRFS rules. Once all user configure rules were removed, aRFS can work again.

2019-05-26net: hns3: initialize CPU reverse mappingJian Shen1-29/+48
Allocate CPU rmap and add entry for each irq. CPU rmap is used in aRFS to get the queue number of the rx completion interrupts. In additional, remove the calling of irq_set_affinity_notifier() in hns3_nic_init_irq(), because we have registered notifier in irq_cpu_rmap_add() for each vector, otherwise it may cause use-after-free issue.

2019-05-26qed*: Add iWARP 100g supportMichal Kalderon1-0/+31
Add iWARP engine affinity setting for supporting iWARP over 100g. iWARP cannot be distinguished by the LLH from L2, hence the engine division will affect L2 as well. For this reason we add a parameter to devlink to determine the engine division.

To enable 100g support for offload protocols each PF gets a dedicated engine to work on from the MFW. This patch modifies the code to use the affined hwfn instead of the leading one.

2019-05-26qed: Add llh ppfid interface and 100g support for offload protocolsMichal Kalderon11-339/+1203
This patch refactors the current llh implementation. It exposes a hw resource called ppfid (port-pfid) and implements an API for configuring the resource. Default configuration which was used until now limited the number of filters per PF and did not support engine affinity per protocol. The new API enables allocating more filter rules per PF and enables affinitizing protocol packets to a certain engine which enables full 100g protocol offload support.

2019-05-26qed: Modify api for performing a dmae to another PFMichal Kalderon8-39/+52
This patch modifies the dmae API to enable performing a dmae operation to another PF. This enables sharing between the llh entries between PFs and thus increasing the amount of filters per PF under certain configurations. The llh entries require using the dmae since the memory is widebus, which requires atomicity in access.

2019-05-25net: mvpp2: cls: Support steering to RSS contextsMaxime Chevallier1-4/+54
When steering to an RXQ, we can perform an extra RSS step to assign a queue from an RSS table. This is done by setting the RSS_EN attribute in the C2 engine. In that case, the RXQ that is assigned is the global RSS context id, that is then translated to an RSS table using the RXQ2RSS table. An example using ethtool to steer to RXQ 2 and 3 would be : ethtool -X eth0 weight 0 0 1 1 context new (This would print the allocated context id, let's say it's 1) ethtool -N eth0 flow-type udp4 dst-port 1234 context 1 loc 0 The hash parameters are the ones that are globally configured for RSS : ethtool -N eth0 rx-flow-hash udp4 sdfn When an RSS context is removed while there are active classification rules using this context, these rules are removed.

2019-05-25net: mvpp2: cls: Extract the RSS context when parsing the ethtool ruleMaxime Chevallier1-0/+6
ethtool_rx_flow_rule_create takes into parameter the ethtool flow spec, which doesn't contain the rss context id. We therefore need to extract it ourself before parsing the ethtool rule. The FLOW_RSS flag is only set in info->fs.flow_type, and not info->flow_type. Signed-off-by: Maxime Chevallier <maxime.chevallier@bootlin.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2019-05-25net: mvpp2: cls: Use RSS contexts to handle RSS tablesMaxime Chevallier4-41/+255
The PPv2 controller has 8 RSS tables that are shared across all ports on a given PPv2 instance. The previous implementation allocated one table per port, leaving others unused. By using RSS contexts, we can make use of multiple RSS tables per port, one being the default table (always id 0), the other ones being used as destinations for flow steering, in the same way as rx rings. This commit introduces RSS contexts management in the PPv2 driver. We always reserve one table per port, allocated when the port is probed. The global table list is stored in the struct mvpp2, as it's a global resource. Each port then maintains a list of indices in that global table, that way each port can have it's own numbering scheme starting from 0. One limitation that seems unavoidable is that the hashing parameters are shared across all RSS contexts for a given port. Hashing parameters for ctx 0 will be applied to all contexts.

Move fib6_nh to the end of fib6_info and make it an array of size 0. Pass a flag to fib6_info_alloc indicating if the allocation needs to add space for a fib6_nh. The current code path always has a fib6_nh allocated with a fib6_info; with nexthop objects they will be separate. Signed-off-by: David Ahern <dsahern@gmail.com> Signed-off-by: David S.

2019-05-24cxgb4: Revert "cxgb4: Remove SGE_HOST_PAGE_SIZE dependency on page size"Vishal Kulkarni1-0/+11
This reverts commit 2391b0030e241386d710df10e53e2cfc3c5d4fc1 which has introduced regression. Now SGE's BAR2 Doorbell/GTS Page Size is interpreted correctly in the firmware itself by using actual host page size. Hence previous commit needs to be reverted.

2019-05-24enetc: add hardware timestamping supportY.b. Lu6-6/+189
This patch is to add hardware timestamping support for ENETC. On Rx, timestamping is enabled for all frames. On Tx, we only instruct the hardware to timestamp the frames marked accordingly by the stack. Because the RX BD ring dynamic allocation has not been supported and it is too expensive to use extended RX BDs if timestamping is not used, a Kconfig option is used to enable extended RX BDs in order to support hardware timestamping. This option will be removed once RX BD ring dynamic allocation is implemented.

2019-05-24net: fec: fix the clk mismatch in failed_reset pathAndy Duan1-1/+1
Fix the clk mismatch in the error path "failed_reset" because below error path will disable clk_ahb and clk_ipg directly, it should use pm_runtime_put_noidle() instead of pm_runtime_put() to avoid to call runtime resume callback.
