Collision Test (VPHY_COL_TEST)
This bit enables/disables the collision test mode. When set, the collision
signal to the Host MAC is active during transmission from the Host MAC.
Note:
0: Collision test mode disabled
1: Collision test mode enabled
Speed Select MSB (VPHY_SPEED_SEL_MSB)
This bit is not used by the Virtual PHY and has no effect. The value returned
is always 0.
