From c95e2b9eaeadc0f985030ffa0638278acc2d8727 Mon Sep 17 00:00:00 2001 From: Jim Lin Date: Mon, 26 Aug 2013 20:21:09 +0800 Subject: [PATCH] console: usb: kbd: To fix slow TFTP booting TFTP booting is slow when a USB keyboard is installed and stdin has usbkbd added. This fix is to change Ctrl-C polling for USB keyboard to every second when NET transfer is running. My previous patch is expected to be put into usb_kbd_testc(). But it went into usb_kbd_getc() after applied. This patch is to put change in correct place.
