45456e38c4 net: phy: Allow loopback speed selection for PHY drivers 
PHY drivers support loopback mode, but it is not possible to select the
speed of the loopback mode. The speed is chosen by the set_loopback()
operation of the PHY driver. Same is valid for genphy_loopback().

There are PHYs that support loopback with different speeds. Extend
set_loopback() to make loopback speed selection possible.

b01b59a4fa net: phy: Constify struct mdio_device_id 
'struct mdio_device_id' is not modified in these drivers.

Constifying these structures moves some data to a read-only section, so
increase overall security.

On a x86_64, with allmodconfig, as an example:
Before:
======
   text	   data	    bss	    dec	    hex	filename
  27014	  12792	      0	  39806	   9b7e	drivers/net/phy/broadcom.o

After:
=====
   text	   data	    bss	    dec	    hex	filename
  27206	  12600	      0	  39806	   9b7e	drivers/net/phy/broadcom.o

08b47dfdd6 net: phy: adin1100: Add interrupt support for link change 
An interrupt handler was added to the driver as well as functions
to enable interrupts at the phy.

There are several interrupts maskable at the phy, but only link change
interrupts are handled by the driver yet.
