Jumbo Packet; Gigabit Master Slave Mode; Interrupt Moderation - StarTech.com STCST2000SPEXI Manual

Gigabit Master Slave Mode

Decides whether the adapter or link partner, is designated
as the master. The other device is designated as the slave.
Changing the setting can improve link quality with certain link
partners.
NOTE: Some multi-port devices can be forced to master mode.
If forced to master mode, the device can either disconnect or
downshift to a 100-Mbps link. This issue can also occur in a
Forced Slave to Forced Slave mode. Changing this setting can
cause a momentary loss of connectivity.

Interrupt Moderation

Sets the Interrupt Throttle Rate (ITR), the rate at which the
controller moderates interrupts.
The default setting is optimized for common configurations.
Changing this setting can improve network performance on
certain network and system configurations.
Options:
Adaptive (ITR = -1, no interrupts/sec, it is dynamically changed
by the driver)
Off (ITR = 0, no limit)
Minimal (ITR = 200)
Low (ITR = 400)
Medium (ITR = 950)
High (ITR = 2000)
Extreme (ITR = 3600)
