i40e: Align devlink info versions with ice driver and add docs

2023-10-19T16:03:56Z

Align devlink info versions with ice driver so change 'fw.mgmt' version to be 2-digit version [major.minor], add 'fw.mgmt.build' that reports mgmt firmware build number and use '"fw.psid.api' for NVM format version instead of incorrect '"fw.psid'. Additionally add missing i40e devlink documentation.

devlink: Expose port function commands to control IPsec packet offloads

2023-08-28T00:08:45Z

Expose port function commands to enable / disable IPsec packet offloads, this is used to control the port IPsec capabilities. When IPsec packet is disabled for a function of the port (default), function cannot offload IPsec packet operations (encapsulation and XFRM policy offload). When enabled, IPsec packet operations can be offloaded by the function of the port, which includes crypto operation (Encrypt/Decrypt), IPsec encapsulation and XFRM state and policy offload. Example of a PCI VF port which supports IPsec packet offloads: $ devlink port show pci/0000:06:00.0/1 pci/0000:06:00.0/1: type eth netdev enp6s0pf0vf0 flavour pcivf pfnum 0 vfnum 0 function: hw_addr 00:00:00:00:00:00 roce enable ipsec_packet disable $ devlink port function set pci/0000:06:00.0/1 ipsec_packet enable $ devlink port show pci/0000:06:00.0/1 pci/0000:06:00.0/1: type eth netdev enp6s0pf0vf0 flavour pcivf pfnum 0 vfnum 0 function: hw_addr 00:00:00:00:00:00 roce enable ipsec_packet enable Signed-off-by: Dima Chumak Signed-off-by: Leon Romanovsky Signed-off-by: Saeed Mahameed Reviewed-by: Jiri Pirko Link: https://lore.kernel.org/r/20230825062836.103744-3-saeed@kernel.org Signed-off-by: Jakub Kicinski

net/mlx5e: Add recovery flow for tx devlink health reporter for unhealthy PTP SQ

2023-08-14T21:40:20Z

A new check for the tx devlink health reporter is introduced for determining when the PTP port timestamping SQ is considered unhealthy. If there are enough CQEs considered never to be delivered, the space that can be utilized on the SQ decreases significantly, impacting performance and usability of the SQ. The health reporter is triggered when the number of likely never delivered port timestamping CQEs that utilize the space of the PTP SQ is greater than 93.75% of the total capacity of the SQ. A devlink health reporter recover method is also provided for this specific TX error context that restarts the PTP SQ.
