Hello folks, I am trying to add HDLC module support in the menuconfig. However, I am facing difficulties in rebuilding the kernel and modules. My main objective is to get the HDLC supported in kernel 2.6.9. I have a CentOS 4.4 with kernel 2.6.9.42. I need help in finding the best way to add the HDLC support whether through getting an RPM package for it or refering me to the right procedure in rebuilding the kernel. Thank you very much in advance for your help.
