[RFC,net-next,v2,14/17] net: phy: phylink: permit to pass dev_flags to phylink_connect_phy

Commit Message

Christian Marangi May 2, 2021, 11:07 p.m. UTC

Add support for phylink_connect_phy to pass dev_flags to the PHY driver.
Change any user of phylink_connect_phy to pass 0 as dev_flags by
default.
