thorpej f7f8866fea Add a flag that indicates that a device is a HomePNA device. 2001-08-25 01:41:17 +00:00
thorpej 7459c35d44 Clean up 1000BASE-SX autonegotiation, and add a way to advertise
PAUSE capability.
2001-07-27 22:44:59 +00:00
thorpej 424f7a1e65 Make PHY matching all table-driven. 2001-06-02 21:39:38 +00:00
thorpej 2128d9199a Enable frobbing the 1000baseT control register on Gig-E PHYs,
used for hard-wiring master mode, and for advertising the 1000baseT
media options during autonegotiation.

thorpej ea1aed7db2 Make the number of ticks between auto-negotiation tries PHY-specific,
and default every PHY to 5 seconds (what we used before).  If we find
Gig-E media on a PHY, bump it to 10 seconds, since it can take 5
seconds just to negotiate a Gig-E link.

drochner 002851041c re-enable mii_flags in attach args - I've found a use for it: tell the
PHY which support it that a fiber interface is present

thorpej d3a64bd0d8 Add code to recognize and set media on GMII (Gigabit MII) PHYs.
802.3 doens't specify ANAR or ANLPAR bits for GMII.  Need to
use PHY-specific registers for this, for now, which means we
need specific drivers for the Gigabit-capable PHYs (I think the
most common is the BCM5400).

augustss b728f196e9 Comment out some flag stuff that isn't used. Someone should take a look
at this.  There is something fishy with the mii code, the last argument to
mii_attach() is not being used in any meaningful way.
2001-04-13 11:14:55 +00:00
augustss 205b10ed17 Add a flag to mii_flags which will cause autonegotiation to use tsleep()
instead of callout.  This way adapters which need a process context for
PHY register access (e.g. USB adapters) have a chance.

drochner 9e8def737f Reading the IEEE specs shows that the bits have to be reversed when
mapping an OUI to the MII id registers.
Doing this in the MII_OUI() macro would be too complex, so put it into
a helper function and move the MII id register interpretation stuff
into miivar.h.

thorpej 49014bf59f Restructure the PHY entry points to use a structure of entry points
instead of discrete function pointers, and extend this to include
a "reset" entry point.  Make sure any PHY-specific reset routine is
always used, and provide one for the LXT-970 which disables MII
interrupts (as is done for a few other PHYs we have drivers for).

thorpej fc96443d15 New callout mechanism with two major improvements over the old
timeout()/untimeout() API:
- Clients supply callout handle storage, thus eliminating problems of
  resource allocation.
- Insertion and removal of callouts is constant time, important as
  this facility is used quite a lot in the kernel.

The old timeout()/untimeout() API has been removed from the kernel.

thorpej ad61d101be Factor out the tick handling code into a common function, and send
rt_ifmsg's when the link speed or link status changes.
2000-03-06 20:56:56 +00:00
thorpej 8923ca0b00 Make PHY drivers provide a pointer to their status routine, and add
a generic mii_phy_status() that calls back into the PHY.  It doesn't
do anything interesting yet, but it will soon.
2000-02-02 17:50:43 +00:00
thorpej eed75dbc26 Don't dry to diving MIIF_NOISOLATE in the PHY drivers. Instead, pass
flags down from the parent to child vi mii_attach().
2000-02-02 17:09:38 +00:00
thorpej 84dc99fdea Bring some order to the chaos which was the MII code function naming
"conventions".
2000-02-02 08:05:26 +00:00
thorpej c74e0a8db2 Add detachment support to the MII layer. 2000-01-27 16:44:30 +00:00
thorpej bca88a28c8 Add mii_down(), which is used by MAC drivers to inform PHYs that the
interface is now down.  PHYs use this to cancel pending asynchronous
operations.
1999-11-12 18:12:59 +00:00
thorpej bedeeb9896 Allow mii_phy_probe() to be called multiple times, and allow the caller
to specify either the PHY number or the PHY `offset' (1st, 2nd, 3rd, etc.)
to configure.
1999-11-04 00:22:07 +00:00
thorpej 8fc600c3b1 Clean up the code that adds media a little, and make media selection
table-driven in preparation for some other changes to be made.
1999-11-03 22:30:32 +00:00
thorpej 45a337e088 Add a PHY `offset' (e.g. "first PHY on bus, second PHY on bus, ...") to
the PHY's softc.

thorpej 83f9ab3c87 Implement asynchronous autonegotiation when driven by the MII tick
(one-second clock).  Prevents .5s delays every 5 seconds when the interface
is up but there is no link.  Fixes PR 7361.

thorpej 2b695df1dc Common code for media-from-bmcr. 1998-11-05 04:08:01 +00:00
thorpej 2a17544c19 Place the essentially common "ticks" and "active" members into the
mii_softc (generic phy goo), and just switch all of the PHY drivers
(except tlphy, which really does have special stuff) to use an mii_softc
instead of a private one.
1998-11-05 00:19:32 +00:00
thorpej f66039cbce Routines common between the Uknown PHY driver (forthcoming) and other
PHY drivers.  This file has ukphy_status(), which is what PHY drivers
should use if media detection is done by decoding NWay.
1998-11-04 23:59:51 +00:00
thorpej 51da8fc39f Factor out the common reset code. Use the NOISOLATE flags as appropriate
to prevent a PHY from being isolated in the event the MAC can't deal with
this.  (3Com 3c905B-TX, and Intel i82557).
1998-11-04 23:28:15 +00:00
thorpej b097394468 Factor out some common code from all the PHY drivers (autonegotiation, for
now.)
1998-11-04 23:07:15 +00:00
thorpej 844622de9c Define and use generic PHY read/write reg macros. 1998-11-04 22:15:40 +00:00
thorpej 3f8be46d4d Near complete rewrite of the MII layer to present an interface compatible
with BSDI's MII layer to device drivers.
