| |
From: Simon Arlott <simon@fire.lp0.eu>
The sysfs adsl_status attribute ignores (aside from returning -EIO to the user) any error sending a START/STOP command to the device and there is at least one firmware which never sends a response but appears to work regardless. Therefore atm_start should also continue if an error is received so that such firmware is usable.
The official Conexant driver doesn't expect a reply either but this is for another device (E2 router) and a commonly used firmware does respond.
Also, there is no point in changing -ECONNRESET to -ETIMEDOUT since nothing ever checks for either of these values.
