C.6.1 Flow Control Options
PromiscuousVlan 0 Specifies whether a promiscuous VLAN is enabled or not. When
this parameter is set, all the packets with VLAN tags are passed to
an upper level without executing any filtering.
The valid values are:
• 0: disable
• 1: enable
Note: This registry value is not exposed via the UI.
UseRSSForRawIP 1 The execution of RSS on UDP and Raw IP packets. In a forwarding
scenario, one can improve the performance by disabling RSS on
UDP or a raw packet. In such a case, the entire receive processing
of these packets is done on the processor that was defined in
DefaultRecvRingProcessor registry key.
The valid values are:
• 0: disable
• 1: enable
This is also relevant for IPoIB.
Note: This registry value is not exposed via the UI.

performance by disable RSS on UDP or raw packet.
In such a case all the receive processing of these
packets is done on the processor that was defined in
DefaultRecvRingProcessor registry key.
The valid values are:
• 0:disabled
• 1: Enabled
NOTE: This registry value is not exposed via UI.
SingleStream 0 It used to get the maximum bandwidth when using
single stream traffic. When setting the registry key to
enabled the driver will forward the sending packet to
another CPU. This decrease the CPU utilization of the
sender and allows sending in higher rate
The valid values are:
• 0:disabled
• 1: Enabled
NOTE: only relevant for Ethernet and IPoIB
