coalescing.

Time interval between interrupts; the
maximum time for the NIC to coalesce
before it raises an interrupt. For
Coalescing interrupt timer
Gigabit drivers, the parameter is
known as maximum receive coalesce
ticks or maximum send coalesce ticks.

Specifies the Ethernet MAC address
of the remote interface; only valid for
diagnose operation (nwmgr --diag).
Destination MAC address
ixgbeA feature that allows packets to be
steered to different queues based on
Destination Port-based Steering (DPS)
the destination port number of the
packet. This feature can improve
performance with some workloads.
ixgbeEnable/disable round robin mode of
queue assignment for Destination
Port-based Steering.
DPS PQM Round Robin
ixgbeEnable/disable periodic invalidation
of Port-to-queue mapping table entries
for Destination Port-based Steering.
DPS PQM Periodic Invalidation
ixgbeTimer value after which the
port-to-queue mapping table entries
will be invalidated.
DPS PQM Invalidation Timer
iether, gelan, igelanModifies the inbound packet rate
threshold below which the driver
Diagnostics threshold
internal diagnostic for hardware fault
detection will be enabled; for some
drivers, the threshold below which
CKO diagnostics are run. The
diagnostics will be activated when the
packet rate on the interface drops
below this threshold.
ietherModifies interrupt spacing. Can be set
to enable automatic dynamic tuning
in the driver.

maximum number of receive
descriptors for the NIC to coalesce
before it raises an interrupt.
