Message about true NDIS 6.20 receive-side scaling when configuring a team

When creating a new team or adding ports to an existing team, you might receive a message similar to this:

This adapter does not support true NDIS 6.20 Receive-Side Scaling. Receive-Side Scaling will be disabled for the team. Disabling Receive-Side Scaling will negatively impact the performance of the team.

Explanation
You cannot enable RSS on teams containing a mix of adapters supporting different implementations of RSS.

Newer Intel® Ethernet adapters support true NDIS 6.20 Receive Side Scaling (RSS) used in Microsoft Windows 7* and Server 2008 R2*.

Intel Ethernet adapters using the e1e6232, e1e6264, or e1e6232e driver do not support true NDIS 6.20 RSS.

Both implementations of RSS work in Windows 7 and Server 2008 R2 when:

  • Ports are not teamed
  • Teams with adapters supporting the same RSS implementation

What happens if I mix adapters supporting different versions of RSS in a team?
If you attempt to mix adapters supporting different versions of RSS in a team, Intel® PROSet will display a message warning you that RSS will be disabled for the team. You will have the choice to proceed (OK) or to cancel team creation.

Note Disabling RSS will negatively impact the performance of the team. Intel recommends that you do not mix Intel Ethernet adapters that support true NDIS 6.20 RSS with adapters that do not support true NDIS6.20 RSS.
