Can any one let me know the difference in option and sierra kernel modules ? looks like both drivers support GSM modem. And from the source code perspective both look similar. I am able to load sierra module for my Huawei USB dongle E156 and able to connect to internet using pppd. Is it OK to use sierra driver for Huawei in case there is no technical issue? If yes why there are two different modules?
