From: Simon Arlott <[email protected]>
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.
