NAME

       sppp_reopen - notify of physical link loss

SYNOPSIS

       int sppp_reopen  (struct net_device * dev);

ARGUMENTS

       dev    Device that lost the link

DESCRIPTION

       This function informs the synchronous protocol code that the underlying
       link died (for example a carrier drop on X.21)

       We increment the magic numbers to ensure that if the other  end  failed
       to  notice  we will correctly start a new session. It happens do to the
       nature of telco circuits is that you can lose carrier on one endonly.

       Having done this we go back to negotiating. This function may be called
       from an interrupt context.
