This was intended to be a non-functional change. It wasn't. The commit message was thus wrong. In addition it broke arm, and merged crypto related code. Revert with prejudice. This revert skips files touched in r316370 since that commit was since MFCed. This revert also skips files that require $FreeBSD$ property changes. Thank you to those who helped me get out of this mess including but not limited to gonzo, kevans, rgrimes. Requested by: gjb (re)

Bring over the first part of the etherswitch framework - an MDIO bus and

MDIO/MII rendezvous proxy. * Add an 'mdio' bus, which is the "IO" side of an MII bus (but by design can be anything which implements the underlying register access API.) * Add 'miiproxy' and 'mdioproxy', which provides a rendezvous mechanism for MII busses to appear hanging off arbitrary busses (ie, that aren't necessarily a traditional looking MII bus.) MII busses can now hang off anything that implements an mdiobus. For the AR71xx SoC, there's one MDIO bus but two MII busses. So to properly support two or more real PHYs, this can be done: # arge0 MDIO bus - there's no arge1 MDIO bus for AR71xx hint.argemdio.0.at="nexus0" hint.argemdio.0.maddr=0x19000000 hint.argemdio.0.msize=0x1000 hint.argemdio.0.order=0 # Create two mdioproxy instances hint.mdioproxy.0.at="mdio0" hint.mdioproxy.1.at="mdio0" # .. and with a follow-up patch hint.arge.0.mdio=mdioproxy0 hint.arge.1.mdio=mdioproxy0 TODO: * Do a sweep or two and add appropriate locking in mdio/mdioproxy/miiproxy.
