src/external/bsd/top/dist/machine: m_netbsd.c
Log Message:
top: add network in & out bytes to the top display.
inspired by the macos top(1).
the first value displayed is the total in/out bytes since boot,
but each update is the amount since the prior update. the new
fetching code heavily based upon netstat/if.c.
old version:
Swap: 128G Total, 128G Free / Pools: 13G Used
new version:
Swap: 128G Total, 128G Free / Pools: 13G Used, / Network: 26M In, 804K Out
