It appears that some recent linux kernels have introduced some new device that
shows up in /proc/net/dev, but has no statistics. Instead of 0 entries, it
actually contains the text "No statistics available.". This causes the ifTable
data_access code to complain that scanf didn't parse enough values. This patch
ignores devices with no statistics. I'm calling for votes to include it in
5.4.1...
