* Name: phy_notify_subscribe
*
* Description:
* Setup up to deliver signals to the task identified by 'pid' when
* there is any change indicated by an interrupt from the PHY associated
* with 'intf'
*
* NOTE: This function is intended to be called only from an Ethernet
* driver in support of the SIOCMIISIG ioctl command. It should never
* by called directly by application logic.
*
* Input Parameters:
* intf - Provides the name of the network interface, for example, "eth0".
* pid - Identifies the task to receive the signal. The special value
* of zero means to use the pid of the current task.
* event - Describe the way a task is to be notified
*
* Returned Value:
* OK on success; Negated errno on failure.
