How to set the parameters of the sunrpc kernel module correctly in RHEL 5 and 6

Issue

• sunrpc.min\_resvport and sunrpc.max\_resvport parameters are not set at boot even while specified in sysctl.conf. But when sysctl -p is executed after boot, it works. The module sunrpc is not loaded at boot when sysctl -p is done.
• sunrpc module is not persistant across reboot on RHEL 6.5
