Transmit Checksum Offload field
|
This can
be one of the following:
Note
|
This
option affects only packets sent from the interface.
|
|
Receive Checksum Offload field
|
This can
be one of the following:
Note
|
This
option affects only packets received by the interface.
|
|
TCP Segmentation Offload field
|
This can
be one of the following:
Note
|
This
option is also known as Large Send Offload (LSO) and affects only packets sent
from the interface.
|
|
TCP Large Receive Offload field
|
This can
be one of the following:
-
Disabled—The CPU processes all large packets.
-
Enabled—The hardware reassembles all segmented
packets before sending them to the CPU. This option may reduce CPU utilization
and increase inbound throughput.
Note
|
This
option affects only packets received by the interface.
|
|
Receive Side Scaling field
|
RSS
distributes network receive processing across multiple CPUs in multiprocessor
systems. This can be one of the following:
-
Disabled—Network receive processing is always
handled by a single processor even if additional processors are available.
-
Enabled—Network receive processing is shared across
processors whenever possible.
|
Accelerated Receive Flow Steering field
|
Packet
processing for a flow must be performed on the local CPU. This is supported for
Linux operating systems only. This can be one of the following:
|
Network Virtualization using Generic Routing
Encapsulation field
|
Whether
NVGRE overlay hardware offloads for TSO and checksum are enabled. This can be
one of the following:

Virtual Extensible LAN field
|
Whether
VXLAN overlay hardware offloads for TSO and checksum are enabled. This can be
one of the following:
|
Failback Timeout field
|
After a
vNIC has started using its secondary interface, this setting controls how long
the primary interface must be available before the system resumes using the
primary interface for the vNIC.
Enter a
number of seconds between 0 and 600.
|
Interrupt Mode field
|
The
preferred driver interrupt mode. This can be one of the following:
|
Interrupt Coalescing Type field
|
This can
be one of the following:
-
Min—The system waits for the time specified in the
Interrupt Timer field before sending another
interrupt event.
-
Idle—The system does not send an interrupt until
there is a period of no activity lasting as least as long as the time specified
in the
Interrupt Timer field.
|
Interrupt Timer field
|
The
time to wait between interrupts or the idle period that must be encountered
before an interrupt is sent.
Enter a
value between 1 and 65535. To turn off interrupt coalescing, enter 0 (zero) in
this field.
|
RoCE field
|
Whether Remote Direct Memory Access over an Ethernet network is enabled. This can be one of the following:

RoCE Properties area
|
Lists
the RoCE properties. This area is enabled only if you enable RoCE.
|
Queue Pairs
|
The number of queue pairs per adapter.
Enter an integer between 1 and 8192. It is recommended that this number be an integer power of 2.
|
Memory Regions
|
The
number of memory regions per adapter.
Enter an
integer between 1 and 524288. It is recommended that this number be an integer
power of 2.
|
Resource Groups
|
The
number of resource groups per adapter.
Enter an
integer between 1 and 128.
It is recommended that this number be an integer power of 2
