Feature/Change |
Description |
|
Packet Pacing Support for Hairpin Queues |
Added support for the user to set a packet pacing rate on the special queues that forward traffic from one physical port to the other. |
|
Network Interface Connection Tracking Offload |
Added support for Connection Tracking (TC) offload on network interfaces that are in NIC mode, as opposed to SwitchDev mode. Note: This support is currently available for interfaces with physical functions only. |
|
SMP MADs Limitation |
Added support for limiting SMP MADs on the wire using a Send window mechanism. This allows the user to keep track of the outstanding number of SMP MADs per-port, and allows for limiting this number to shape traffic when the pace of SMP MADs requires control. |
|
Sampling Action Direct Rule API Support |
Added Direct Rule (DR) API support for sampling action to allow duplication and sampling of some ratio of the traffic. The API also allows to perform a set of different DR actions on the sampled traffic. |

SA MAD Congestion Control |
SA MAD Congestion Control feature is restored in MLNX_OFED v5.1-2. |
