+ μrngd is OpenWrt's micro non-physical true random number generator based on
+ timing jitter.
+
+ Using the Jitter RNG core, the rngd provides an entropy source that feeds into
+ the Linux /dev/random device if its entropy runs low. It updates the
+ /dev/random entropy estimator such that the newly provided entropy unblocks
+ /dev/random.
+
+ The seeding of /dev/random also ensures that /dev/urandom benefits from
+ entropy. Especially during boot time, when the entropy of Linux is low, the
+ Jitter RNGd provides a source of sufficient entropy.
