TFTP booting is observed a little bit slow, especially when a USB keyboard is installed. The fix is to check whether Ctrl-C key is pressed every CONFIG_CTRLC_POLL_MS ms. If CONFIG_CTRLC_POLL_MS is not defined in configuration file, we define it as 1000.

Don't set such a default. If this is good for you, OK. But for all others, the behaviour should not change at all.
Also, are you positively sure that your callto get_timer() does not mess up with other timers in the network subsystem?
OK. I will rewrite and check again. Thanks.
