Subject: [PATCH 06/10] net: phy: provide whether link has changed in
 | 
						|
 c37_read_status
 | 
						|
 | 
						|
Some PHY driver might require additional regs call after
 | 
						|
genphy_c37_read_status() is called.
 | 
						|
 | 
						|
Expand genphy_c37_read_status to provide a bool wheather the link has
 | 
						|
changed or not to permit PHY driver to skip additional regs call if
 | 
						|
nothing has changed.
 | 
						|
 | 
						|
Every user of genphy_c37_read_status() is updated with the new
 | 
						|
additional bool.
