overhead.
Thisoption affectsonly packets sent from the
interface.
Note
TransmitChecksum Offload field
Thiscan be one of the following:
Disabled—TheCPU validates all packetchecksums.
Enabled—TheCPU sends all packet checksums to the hardware
forvalidation. This optionmay reduceCPU overhead.
Thisoption affectsonly packets received by the
interface.
Note
ReceiveChecksum Offload field
Thiscan be one of the following:
Disabled—TheCPU segments large TCP packets.
Enabled—TheCPU sends large TCP packets to the hardware to
besegmented. This option may reduce CPU overhead and increase
throughputrate.
Thisoption is also known asLarge Send Offload (LSO) and
affectsonly packets sent from the interface.
Note
TCPSegmentation Offload field
Thiscan be one of the following:
Disabled—TheCPU processes all large packets.
Enabled—Thehardware reassembles all segmented packets before
sendingthem to the CPU. This option may reduce CPU utilization
andincrease inbound throughput.
Thisoption affectsonly packets received by the
interface.
