Description
Number of receive queue resources to allocate, between 1 and 256.
Number of descriptors in each receive queue, between 64 and 4096.
Description
Number of transmit queue resources to allocate, between 1 and 256.
Number of descriptors in each transmit queue, between 64 and 4096.
Description
Number of completion queue resources to allocate. In general, the number
should equal the number of transmit queue resources, plus the number of
receive queue resources. Enter an integer between 1 and 512.
Number of descriptors in each completion queue. This value cannot be
changed.
Description
If this option is selected, the CPU sends large TCP packets to the hardware to
be segmented. This option might reduce CPU overhead and increase
throughput rate.
If this option is not selected, the CPU segments large packets.
This option is also known as Large Send Offload (LSO).
If this option is selected, the CPU sends all packet checksums to the hardware
for validation. This option might reduce CPU overhead.
If this option is not selected, the CPU validates all packet checksums.
If this option is selected, the CPU sends all packets to the hardware so that the
checksum can be calculated. This option might reduce CPU overhead.
If this option is not selected, the CPU calculates all packet checksums.
If this option is selected, the hardware reassembles all segmented packets
before sending them to the CPU. This option might reduce CPU utilization and
increase inbound throughput.
If this option is not selected, the CPU processes all large packets.
