Realtek RTL8111E

Yeah, realtek is quite common for onboard ethernet in cheap consumer motherboards.

The :3 is the bitfield that describes what kind of debug information to log, so in binary 3 = 2 + 1, which means the two least significant bits are on, so you're seeing stuff for log level 1 and 2.

To store the output you need to enable either syslog or serial console. http://ipxe.org/console should help you out. Since you're debugging a network driver you mostly need to use serial (and the machine you're trying to boot must have a real serial port, USB isn't supported).
