While carrying endurance testing of my system, i came accross a problem:
At some point I was unable to get the ppp link up. The problem was that my
device option had changed from /dev/ttyHS5 to ppp0 and so the 3g hotplug
refused to declare the wwan proto as available.
This patch fix this issue.
My test is running the following in a loop on a mini PCIe option modem:
- switch modem on
- wait for GSM registration
- ifup wwan
- ifdown wwan
- switch off modem
