There are no module callers in-tree and it's hard to justify
why anyone would init or flush addresses of a netdev (note
the flush is more of a destructor, it frees netdev->dev_addr).

Commit 406f42fa0d ("net-next: When a bond have a massive amount
of VLANs...") introduced a rbtree for faster Ethernet address look
up. We converted all users to make modifications via appropriate
helpers, make netdev->dev_addr const.
The update helpers need to upcast from the buffer to
struct netdev_hw_addr.

Add support for the TI DP83561-SP Gigabit ethernet phy device.
The dp83561-sp is a radiation hardened space grade gigabit ethernet
PHY. It has been tested for single event latch upto 121 MeV, the
critical reliability parameter for space designs. It interfaces directly to
twisted pair media through an external transformer. And the device also
interfaces directly to the MAC layer through Reduced GMII (RGMII) and MII.
DP83867, DP83869 and DP83561-SP, all these parts support 1000Base-T/
100Base-TX/ and 10Base-Te standards and have similar register map for
the core functionality.
The data sheet for this part is at https://www.ti.com/product/DP83561-SP
