usbether: Fixed bug when using with PXA25X chips
PXA25X chips don't support alternate settings so driver uses non-CDC driver. But only code defined between DEV_CONFIG_CDC signals that network is up. This patch is fixing this bug by signaling that network is up after USB SET_INTERFACE request. Signed-off-by: Lukasz Dalek <luk0104@gmail.com>
