[U-Boot] [PATCH] tsec.c bug: Every key typing in netconsole prints the Eth link mode

[Michael Zaidman]

The problem description:
The Ethernet link operation mode printing (such as "Speed: 1000,
full duplex") accomplishes every key typing when communicating via
netconsole to the mpc834x based board. The string is printed by
adjust_link() routine of tsec.c, which in turn is part of the
eth_init routine called at every netloop entry.

The solution:
Do not print the string when compiled with CONFIG_NETCONSOLE and
stdin or stdout is set to "nc"
