/**
* Represents the globally unique identifier of a {@link Channel}.
*
* The identifier is generated from various sources listed in the following:
*
* - MAC address (EUI-48 or EUI-64) or the network adapter, preferably a globally unique one,
* - the current process ID,
* - {@link System#currentTimeMillis()},
* - {@link System#nanoTime()},
* - a random 32-bit integer, and
* - a sequentially incremented 32-bit integer.
*
*
*
* The global uniqueness of the generated identifier mostly depends on the MAC address and the current process ID,
* which are auto-detected at the class-loading time in best-effort manner. If all attempts to acquire them fail,
* a warning message is logged, and random values will be used instead. Alternatively, you can specify them manually
* via system properties:
*
* - {@code io.netty.machineId} - hexadecimal representation of 48 (or 64) bit integer,
* optionally separated by colon or hyphen.
* - {@code io.netty.processId} - an integer between 0 and 65535
*
