Step 12
In the Completion Queue area, review the information in the following fields:
DescriptionName
The number of completion queue resources to allocate. In general, the
number of completion queue resources you should allocate is equal to

In the TCP Offload area, review the information in the following fields:
DescriptionName
If checked, the CPU sends large TCP packets to the hardware to be
segmented. This option may reduce CPU overhead and increase
throughput rate.
If cleared, the CPU segments large packets.
This option is also known as Large Send Offload
(LSO).
Note
Enable TCP Segmentation
Offload check box
If checked, the CPU sends all packet checksums to the hardware for
validation. This option may reduce CPU overhead.
If cleared, the CPU validates all packet checksums.
Enable TCP Rx Offload
Checksum Validation check box
If checked, the CPU sends all packets to the hardware so that the
checksum can be calculated. This option may reduce CPU overhead.
If cleared, the CPU calculates all packet checksums.
Enable TCP Tx Offload
Checksum Generation check box
If checked, the hardware reassembles all segmented packets before
sending them to the CPU. This option may reduce CPU utilization and
increase inbound throughput.
If cleared, the CPU processes all large packets.
Enable Large Receive check box
