Here is a snippet from my current dwm status shell script which sums up
all interfaces
except the loopback one.

rx_now=0
tx_now=0
for i in /sys/class/net/*; do
         if [[ -d "$i" && ${i##*/} != "lo" ]]; then
                 if [[ -f "$i/statistics/rx_bytes" ]]; then
                         let rx_now=($rx_now+`cat
$i/statistics/rx_bytes`)
                 fi
                 if [[ -f "$i/statistics/tx_bytes" ]]; then
                         let tx_now=($tx_now+`cat
$i/statistics/tx_bytes`)
                 fi
         fi
done
let rx_rate=($rx_now-$rx_old)
let tx_rate=($tx_now-$tx_old)
