Setting Parameters in the /etc/system File

To conﬁgure the qfe driver parameters for all SUNW,qfe devices in the system so that the parameter variables are always effective (even after rebooting the system), enter the parameter variables in the /etc/system ﬁle. When you reboot the system, the system reads the /etc/system ﬁle and sets these parameter variables in the qfe module in the operating system kernel.

Table C–9 lists the variables you can set in the /etc/system ﬁle.
