/****************************************************************************
* Function: sam_ioctl
*
* Description:
* Handles driver ioctl calls:
*
* SIOCMIINOTIFY - Set up to received notifications from PHY interrupting
* events.
*
* SIOCGMIIPHY, SIOCGMIIREG, and SIOCSMIIREG:
* Executes the SIOCxMIIxxx command and responds using the request struct
* that must be provided as its 2nd parameter.
*
* When called with SIOCGMIIPHY it will get the PHY address for the device
* and write it to the req->phy_id field of the request struct.
*
* When called with SIOCGMIIREG it will read a register of the PHY that is
* specified using the req->reg_no struct field and then write its output
* to the req->val_out field.
*
* When called with SIOCSMIIREG it will write to a register of the PHY that
* is specified using the req->reg_no struct field and use req->val_in as
* its input.
*
* Parameters:
* dev - Ethernet device structure
* cmd - SIOCxMIIxxx command code
* arg - Request structure also used to return values
*
* Returned Value: Negated errno on failure.
*
* Assumptions:
*
