Changes and New Features
Component | Feature/Change | Description |
Netdev | Increase Netdev Interface Max Channels | [ConnectX-4 and above] Added a feature that bumps the software upper bound of the netdev max channels from 128 to 256. This is relevant for systems with a high number of cores. |
Configuration from VM/VF for Full Offload Transport Mode | [ConnectX-6 Dx and above] Added support for two new Boolean attributes of a port function: ipsec_crypto and ipsec_packet. The goal is to provide a level of granularity for controlling VF IPsec offload capabilities, similar to what is currently offered in the software mode. This allows users to decide if they want both types of IPsec offload enabled for a VF, just one of them, or none at all (which is the default). A hypervisor-level control parameters to set the IPsec functionality of PCI VF devices passed through to guests. The administrator of a hypervisor host may choose to change the settings of a port function from the defaults configured by the device firmware. | |
IPSec Transparent Mode Support in Kernel Upstream (FDB) | [ConnectX-6 Dx and above] Added support for IPSec packet offload in switchdev mode. | |
Expose SF Devlink Resource | [ConnectX-4 and above] Added a feature to allow user applications to view the maximum number of SFs configured on the system via general linux API, devlink resource. | |
Support MACsec Operations Offload | [ConnectX-7 and above] Added support for MACsec operations' offload to the hardware , which yields greater performance than software counterpart, and most importantly enables sending MACsec encrypted RoCE traffic, which is not possible in software MACsec. Support Added in FW version : 28.35.0328. | |
SF Orchestration - Light Weight Local SFs | [ConnectX-5 and above] Added a feature to p robe local SFs with devlink instance only. local SFs= SFs spawn over the device (PF/ECPF) which is the E-switch manager. This feature will decrease the amount of time needed to probe and configure SFs, by saving the time of devlink reload of the SF. | |
4 ports VF LAG | [ConnectX-7] Enable VF LAG over 4 ports HCAs. Note
Only LAG with all HCA ports is supported.
