To be fair to Krzysztof, the "non-compiling functionality" I cut simply
came from the fact that latest sethdlc utility contained code related to
CONFIG_HDLC_RAW_ETH option which wasn't available in vanilla 2.4.21-pre.
Please note that this specific code exists in 2.4.22-pre3-ac but not in
plain Marcelo's 2.4.22-pre.
