2019-05-26qed: Modify offload protocols to use the affined engineMichal Kalderon4-189/+273
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. The offload protocols require the ll2 to be opened on both engines, and not just the affined hwfn.

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.

As of today, the classification offload implementation only supports 4 different rules to be offloaded.

2019-05-25flow_offload: use struct_size() in kzalloc()Gustavo A. R. Silva1-2/+1
One of the more common cases of allocation size calculations is finding the size of a structure that has a zero-sized array at the end, along with memory for some number of elements for that array. For example: struct foo { int stuff; struct boo entry[]; }; instance = kzalloc(sizeof(struct foo) + count * sizeof(struct boo), GFP_KERNEL); Instead of leaving these open-coded and prone to type mistakes, we can now use the new struct_size() helper: instance = kzalloc(struct_size(instance, entry, count), GFP_KERNEL); This code was detected with the help of Coccinelle.

2019-05-24selftests/net: SO_TXTIME with ETF and FQWillem de Bruijn5-1/+332
The SO_TXTIME API enables packet tranmission with delayed delivery. This is currently supported by the ETF and FQ packet schedulers. Evaluate the interface with both schedulers. Install the scheduler and send a variety of packets streams: without delay, with one delayed packet, with multiple ordered delays and with reordering. Verify that packets are released by the scheduler in expected order. The ETF qdisc requires a timestamp in the future on every packet. It needs a delay on the qdisc else the packet is dropped on dequeue for having a delivery time in the past. The test value is experimentally derived. ETF requires clock_id CLOCK_TAI. It checks this base and drops for non-conformance. The FQ qdisc expects clock_id CLOCK_MONOTONIC, the base used by TCP as of commit fb420d5d91c1 ("tcp/fq: move back to CLOCK_MONOTONIC"). Within a flow there is an expecation of ordered delivery, as shown by delivery times of test 4. The FQ qdisc does not require all packets to have timestamps and does not drop for non-conformance. The large (msec) delays are chosen to avoid flakiness. Output: SO_TXTIME ipv6 clock monotonic payload:a delay:28 expected:0 (us) SO_TXTIME ipv4 clock monotonic payload:a delay:38 expected:0 (us) SO_TXTIME ipv6 clock monotonic payload:a delay:40 expected:0 (us) SO_TXTIME ipv4 clock monotonic payload:a delay:33 expected:0 (us) SO_TXTIME ipv6 clock monotonic payload:a delay:10120 expected:10000 (us) SO_TXTIME ipv4 clock monotonic payload:a delay:10102 expected:10000 (us) [.. etc ..] OK.
