Hi,
if I install a module with specific parameter, will this parameters applied next time system boots?
for exampe, I want to disable InterruptThrottleRate
modprobe e1000e InterruptThrottleRate=0
Is this parameter apllied only for this run, or this module will always use this parameter when it's loaded by the system?

All options are only valid until the module is unloaded again, or a system reboot. To make the changes permanent, on modern distributions, create a file called 'e1000e.conf' in /etc/modprobe.d with the options. Eg:

 cat > /etc/modprobe.d/e1000e.conf << EOF
options e1000e InterruptThrottleRate=0
EOF

Or, if it should be specific to just one network interface instead of globally for all:

cat > /etc/modprobe.d/e1000e.conf << EOF
alias eth0 e1000e # assuming it's eth0 you want to set the option for
options eth0 InterruptThrottleRate=0
