New Revision: 235818
URL: http://svn.freebsd.org/changeset/base/235818
Log:
MFC r235151:
Implement basic remote PHY support. Remote PHY allows the
controller to perform MDIO type accesses to a remote transceiver
using message pages defined through MRBE(multirate backplane
ethernet). It's used in blade systems(e.g Dell Blade m610) which
are connected to pass-through blades rather than traditional
switches.
This change directly manipulates firmware's mailboxes to control
remote PHY such that it does not use mii(4). Alternatively, as
David said, it could be implemented in brgphy(4) by creating a fake
PHY and let brgphy(4) do necessary mii accesses and bce(4) can
implement mailbox accesses based on the type of brgphy(4)'s mii
accesses. Personally, I think it would make brgphy(4) hard to
maintain since it would have to access many bce(4) registers in
brgphy(4). Given that there are users who are suffering from lack
of remote PHY support, it would be better to get working system
rather than waiting for complete/perfect implementation.
