[Observium] No graphs for 64bit network ports on arm

Hi All,

Ive spotted a few weird issue with my new setup running on arm?

1. The first 4 ports on our TPLink switches are being detected as 64Bit and then the rest of the ports are 32Bit ? 2. the 64bit graphs are showing 0 for everything, even though the output from the command line shows stats? (See https://pastebin.com/raw/qP4T1Fa9 https://pastebin.com/raw/qP4T1Fa9) 3. The graphs are being generated so the RRDs are fine, but the graphs are blank?

Regards

Simon
