I don't understand this driver too well, but should this be using
ext_read() and ext_write().
I'm also woundering if it would be good to implement the .read_page
and .write_page members in phy_driver and then use phy_write_paged()
and phy_write_paged() and phy_modify_paged(), which should do better
locking.
I don't feel comfortable implementing .read_page and write_page members
as I have
only one PHY on my board so I'll not be able to test all the broadcast
thing.
If that's OK with you, I'll use the ext_read() and ext_write()
