The driver configuration parameters are global parameters used by all network driver instances.

The driver-level configuration values discussed in this section are in the following locations on your
system:
• Linux - /etc/modprobe.conf
• VMware - /etc/vmware/esx.conf
• Windows - Device Manager
NOTE
These parameters are should only be changed from the default values by power users with great
caution.
