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 411a31adb2 - Go to splimp() when sending the rtsock message regarding link status.
- Would like to notify protocols if a link goes up or down, to e.g.
  restart Duplicate Address Detection, etc.  Add a comment to this
  effect.

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.

thorpej a084fd2f81 Some PHYs go off into left field for a few seconds if you attempt to kick
autonegotiation while it's already enabled.

thorpej 9ff57fe506 Oops, missing return; 2000-02-03 05:38:57 +00:00
thorpej 22fe15d7b4 Let mii_phy_setmedia() handle the IFM_AUTO case, too. 2000-02-02 23:34:56 +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.

thorpej 84dc99fdea Bring some order to the chaos which was the MII code function naming
"conventions".

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.

thorpej bc82bff1dc Don't add any loopback versions of media, for now. 1999-11-03 22:32:45 +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.

drochner f04cb4036f move common support functions for phy drivers from mii.c to mii_physubr.c,
so that they are not includes if no PHY is configured
(avoids code bloat if an interface driver has the "mii" attribute but
mii is not used by the particular version)

kleink 5ea46286eb mii_phy_auto(): don't rely on an implicit declaration of the waitfor argument. 1999-04-26 14:48:57 +00:00
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 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.)
