Report network throughput in bits, which is what everything downstream says

Browse Source 
/proc/net/dev counts octets; the field is named rx_bps, vvFmtBps renders Kb/s
and Mb/s, and the Monitor card prints it directly under the NIC link speed from
/sys/class/net/*/speed, which genuinely is megabits. So the one figure you would
read against the link understated traffic eightfold — 811 KB/s shown as "0.8
Mb/s" beside a 10 Gb/s link when it was 6.5. Converted at the source so the
field name stops lying; both consumers are bit-labelled or relative.

// ×8, because /proc/net/dev counts octets and everything downstream of here says bits.
//
// The field is named rx_bps, vvFmtBps() renders it as Kb/s, Mb/s and Gb/s, and the Monitor
// card prints it directly beneath the NIC's link speed — which comes from
// /sys/class/net/*/speed and genuinely is megabits. So the one number on that card you would
// read against the link was understating traffic by a factor of eight: 811 KB/s of real
// traffic displayed as "0.8 Mb/s" next to a 10 Gb/s link, when it was 6.5 Mb/s.
//
// Converted at the source rather than in the formatter so the field name stops lying. Both
// consumers are the Monitor card's rate readout and its history graph, and both are relative
// or bit-labelled, so neither changes meaning — only magnitude, to the correct one.
