ReturnPacketThreshold 0 The allowed number of free received packets on the rings.
Any number above it will cause the driver to return the
packet to the hardware immediately.
When the value is set to 0, the adapter uses 2/3 of the
received ring size.
The valid values are: 0 to 4096.
Note: This registry value is not exposed via the UI.
NumTcb 16 The number of send buffers that the driver allocates for
sending purposes. Each buffer is in LSO size, if LSO is
enabled, or in MTU size, otherwise.
The valid values are 1 up to 64.
Note: This registry value is not exposed via the UI.
ThreadPoll 10000 The number of cycles that should be passed without receiv-
ing any packet before the polling mechanism stops when
using polling completion method for receiving. Afterwards,
receiving new packets will generate an interrupt that
reschedules the polling mechanism.
The valid values are 0 up to 200000.
Note: This registry value is not exposed via the UI.
AverageFactor 16 The weight of the last polling in the decision whether to
continue the polling or give up when using polling comple-
tion method for receiving.
The valid values are 0 up to 256.
Note: This registry value is not exposed via the UI.
AveragePollThreshold 10 The average threshold polling number when using polling
completion method for receiving. If the average number is
higher than this value, the adapter continues to poll.
The valid values are 0 up to 1000.
Note: This registry value is not exposed via the UI.
ThisPollThreshold 100 The threshold number of the last polling cycle when using
polling completion method for receiving. If the number of
packets received in the last polling cycle is higher than this
value, the adapter continues to poll
The valid values are 0 up to 1000.
Note: This registry value is not exposed via the UI.
