This flag is to make console aware that NET transfer is running or not. Signed-off-by: Jim Lin <jilin@nvidia.com> --- Changes in v2: 1. Change configuration name from CONFIG_CTRLC_POLL_MS to CONFIG_CTRLC_POLL_S. 2. New code will be executed only when CONFIG_CTRLC_POLL_S is defined in configuration header file. 3. Add description in README.console. Changes in v3: 1. Move changes to common/usb_kbd.c and doc/README.usb 2. Rename config setting to CONFIG_USBKB_TESTC_PERIOD. 3. Remove slow response on USB-keyboard input when TFTP boot is not running. Changes in v4: 1. Remove changes in doc/README.usb, common/usb_kbd.c and CONFIG_USBKB_TESTC_PERIOD 2. Modify net/net.c Changes in v5: 1. Change variable name to ctrlc_t_start. 2. Use two calls of get_timer(0) to get time gap. Changes in v6: 1. In common/usb_kbd.c, check net_busy_flag to determine whether we poll USB keyboard status. 2. In include/usb.h, add external variable declaration net_busy_flag Changes in v7: 1. Add CONFIG_USB_KEYBOARD Changes in v8: 1. net/net.c, add __maybe_unused for variable net_busy_flag. net/net.c | 11 +++++++++++ 1 files changed, 11 insertions(+), 0 deletions(-)
