[U-Boot] [PATCH V3 2/2] USB-CDC: called handle_interrupts inside usb_eth_send

2010-08-15 Thread Stefano Babic 
The patch removes an endless loop  in the usb_eth_send
if the tx_complete is not called before going
in the loop. The driver interrupt routine is called
allowing the driver to check if the TX is completed.

Hi,

2010/8/15 Stefano Babic sba...@denx.de:
 The patch removes an endless loop  in the usb_eth_send
 if the tx_complete is not called before going
 in the loop. The driver interrupt routine is called
 allowing the driver to check if the TX is completed.
