- SR-IOV - Virtual Functions (VF) per Port - The maximum Virtual Functions (VF) per port is 127.

Bug Fixes:

- Fixed an issue which caused bi-directional traffic 10% BW degradation in Multihost.
- Increased the CQE zipping aggressive mode timer to 9000
- Moving IPoIB enhanced QP to ERR or RST state results in the corruption of the service_type and pm_state in the QPC.
- Attaching RoCE IPv4 QPs to MCG when the vport state is set to toggle (DOWN/UP), prevents the QPs that are listed on that MCG from receiving any traffic.
- When arming SRQ for limit event, the device might issue an event with context_index=0.
- Occasionally, when moving UD QP from error state to RTS, the QP re-enters the error state.
- When performing Pkey check for IPoIB enhanced traffic, the Pkey membership bit is ignored.
- Stopping the Rate Limiter while traffic is being transmitted might cause the adapter card to hang.
- Privileged Vport egress traffic is not blocked when Vport is not active
- PF direct pass-through is not supported in InfiniBand (since PF FLR is not supported)
- Missing invalidation upon Set().pkey leads to bad Pkey checks.

About Network Adapter Drivers:

When connected, the operating system usually installs a generic driver that helps the computer to recognize the newly attached device.

However, proper software must be applied if you want to make use of all features that the network adapter has available. This task also allows computers to properly recognize all device characteristics such as manufacturer, chipset, technology, and others.

Updating the adapter's drivers and utilities version might improve overall performance and stability, increase transfer speeds, fix different compatibility problems and several network-related errors, as well as bring various other changes.

To install this release, simply get the package, extract it if necessary, run the setup, and follow the instructions displayed on-screen. When done, don't forget to perform a system restart and reconnect the network adapter to make sure that all changes take effect properly.

Without further ado, if you intend to apply this version, click the download button and install the package. Moreover, check with our website as often as possible so that you don't miss a single new release.
