thorpej 424f7a1e65 Make PHY matching all table-driven. 2001-06-02 21:39:38 +00:00
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 1ea0cb1ea4 support the fiber output of the PHY device, enabled if the MIIF_HAVEFIBER
flag is passed in from the board driver

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 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 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 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".

thorpej c74e0a8db2 Add detachment support to the MII layer. 2000-01-27 16:44:30 +00:00
pk 03c8221ad0 Use BMSR to test for `negotiation complete'; the alternative bit in the
LXT vendor register 20 is latching high and resets to low on read causing
subsequent status request to return `IFM_NONE'.
1999-12-21 10:47:00 +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 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 23ddff5688 use the new "xx" prefixed OUIs because the mapping to the ID register
bits differs from the MII_OUI() way
1999-05-14 11:40:28 +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 2b695df1dc Common code for media-from-bmcr. 1998-11-05 04:08:01 +00:00
thorpej aabf2a0809 In the status routine, always use the media selected in the BMCR if
autonegotiation is not enabled.  This is more reliable on many PHYs,
and requires fewer register reads.

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 ad8b66c7c8 Return a higher-priority match than 1. These are specific drivers. This
allows for a "generic unknown PHY" driver to be implemented.
1998-11-04 23:44:09 +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 1f074c785d When doing a media change service request, use the media word from the
current ifmedia_entry, not from the user-supplied media word.  The
user supplied media word may not necessarily match e.g. instance (if
the parent MAC driver is intentionally ignoring instance if its expecting
multiple PHYs with non-overlapping media, e.g. TI ThunderLAN) the media
word we are actually switching to.

Since PHY drivers use `instance' to determine if they should isolate
themselves, the ThunderLAN PHY was sometimes being incorrectly isolated
when in fact the user attempted to select that PHY (for e.g. BNC operation).
