2024-02-01octeontx2-pf: Remove xdp queues on program detachGeetha sowjanya1-1/+0
XDP queues are created/destroyed when a XDP program is attached/detached. In current driver xdp_queues are not getting destroyed on program exit due to incorrect xdp_queue and tot_tx_queue count values. This patch fixes the issue by setting tot_tx_queue and xdp_queue count to correct values. It also fixes xdp.data_hard_start address.

2023-12-14net: ethtool: get rid of get/set_rxfh_context functionsAhmed Zaki1-38/+25
Add the RSS context parameters to struct ethtool_rxfh_param and use the get/set_rxfh to handle the RSS contexts as well. This is part 2/2 of the fix suggested in [1]: - Add a rss_context member to the argument struct and a capability like cap_link_lanes_supported to indicate whether driver supports rss contexts, then you can remove *et_rxfh_context functions, and instead call *et_rxfh() with a non-zero rss_context.

2023-12-14net: ethtool: pass a pointer to parameters to get/set_rxfh ethtool opsAhmed Zaki1-19/+22
The get/set_rxfh ethtool ops currently takes the rxfh (RSS) parameters as direct function arguments. This will force us to change the API (and all drivers' functions) every time some new parameters are added. This is part 1/2 of the fix, as suggested in [1]: - First simplify the code by always providing a pointer to all params (indir, key and func); the fact that some of them may be NULL seems like a weird historic thing or a premature optimization. It will simplify the drivers if all pointers are always present. - Then make the functions take a dev pointer, and a pointer to a single struct wrapping all arguments. The set_* should also take an extack.

As virtual function (vf) shares same physical link same API is used for both the drivers and for loop back drivers simply returns the fixed values as its does not have physical link. ethtool eth3 Settings for eth3: Supported ports: [ ] Supported link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full 1000baseT/Half 1000baseT/Full 10000baseKR/Full 1000baseX/Full Supports auto-negotiation: No Supported FEC modes: BaseR RS Advertised link modes: Not reported Advertised pause frame use: No Advertised auto-negotiation: No Advertised FEC modes: None ethtool lbk0 Settings for lbk0: Speed: 100000Mb/s Duplex: Full Signed-off-by: Christina Jacob <cjacob@marvell.com> Signed-off-by: Sunil Goutham <sgoutham@marvell.com> Signed-off-by: Hariprasad Kelam <hkelam@marvell.com> Reviewed-by: Jesse Brandeburg <jesse.brandeburg@intel.com> Signed-off-by: David S.

By default ESP/AH fields are not considered for RSS and needs to be set explicitly as below: ethtool -U eth0 rx-flow-hash esp4 sdfn or ethtool -U eth0 rx-flow-hash ah4 sdfn or ethtool -U eth0 rx-flow-hash esp6 sdfn or ethtool -U eth0 rx-flow-hash ah6 sdfn To disable hashing of ESP fields: ethtool -U eth0 rx-flow-hash esp4 sd or ethtool -U eth0 rx-flow-hash ah4 sd or ethtool -U eth0 rx-flow-hash esp6 sd or ethtool -U eth0 rx-flow-hash ah6 sd Signed-off-by: Subbaraya Sundeep <sbhatta@marvell.com> Signed-off-by: Sunil Kovvuri Goutham <sgoutham@marvell.com> Link: https://lore.kernel.org/r/1611378552-13288-1-git-send-email-sundeep.lkml@gmail.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>
2021-01-06octeontx2-pf: Add RSS multi group supportGeetha sowjanya1-28/+105
Hardware supports 8 RSS groups per interface. Currently we are using only group '0'. This patch allows user to create new RSS groups/contexts and use the same as destination for flow steering rules. usage: To steer the traffic to RQ 2,3 ethtool -X eth0 weight 0 0 1 1 context new (It will print the allocated context id number) New RSS context is 1 ethtool -N eth0 flow-type tcp4 dst-port 80 context 1 loc 1 To delete the context ethtool -X eth0 context 1 delete When an RSS context is removed, the active classification rules using this context are also removed. Change-log: v4 - Fixed compiletime warning. - Address Saeed's comments on v3. v3 - Coverted otx2_set_rxfh() to use new function. v2 - Removed unrelated whitespace - Coverted otx2_get_rxfh() to use new function.

2020-11-18octeontx2-pf: Add support for ethtool ntuple filtersSubbaraya Sundeep1-2/+56
This patch adds support for adding and deleting ethtool ntuple filters. The filters for ether, ipv4, ipv6, tcp, udp and sctp are supported. The mask is also supported. The supported actions are drop and direct to a queue. Additionally we support FLOW_EXT field vlan_tci and FLOW_MAC_EXT. The NIX PF will allocate total 32 MCAM entries for the use of ethtool ntuple filters. The Administrative Function(AF) will install/delete the MCAM rules when NIX PF sends mailbox message to install/delete the ntuple filters. Ethtool ntuple filters support is restricted to PFs as of now and PF can install ntuple filters to direct the traffic to its VFs. Hence added a separate callback for VFs to get/set RSS configuration.

Added ethtool support for VF devices for - Driver stats, Tx/Rx perqueue stats - Set/show Rx/Tx queue count - Set/show Rx/Tx ring sizes - Set/show IRQ coalescing parameters - RSS configuration etc It's the PF which owns the interface, hence VF cannot display underlying CGX interface stats.
