/*

* openuf - sysinfo.h
|
|
*
|
|
* Reads system statistics (CPU, RAM, interfaces, radios).
|
|
* All readings come directly from the Linux kernel:
|
|
*
|
|
* /proc/stat → CPU usage (deltas between two snapshots)
|
|
* /proc/meminfo → total/free/buffer/cache memory
|
|
* /proc/net/dev → rx/tx counters per interface
|
|
* /sys/class/net/ → speed, duplex, operstate, MAC
|
|
* iw dev <if> info → current channel, TX power
|
|
* iw dev <if> survey dump → channel utilization
