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().

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 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.

thorpej e314d1d844 Correct the sense of the PCR_FLINK100 bit. From Dave Sainty, PR #7832. 1999-07-14 23:57:36 +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 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.

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).

thorpej ae8bdb1e72 Make sure CIMDIS is set and FLINK is clear in the PCR. 1998-08-14 00:23:26 +00:00
thorpej 94e489e277 If the autonegotiation is enabled, the PAR doesn't indicate duplex mode
properly!  Work around this by determing current active media by taking
the highest-order common bit of our advertised capabilites and the link
partner's.

If the link partner doens't do autonegotiation, then parallel detection will
pick up the media type, which will never be full-duplex, so reading the PAR
is ok in this case.

Bug pointed out by Matthias Drochner, work-around inspired by reading
the dp83840 manual, section 3.9 (IEEE 802.3u auto-negotiation).
1998-08-12 22:41:21 +00:00
thorpej 981f0cd0d0 If autonegotiation is enabled in the BMSR, and the BMCR doens't claim
that it has completed, report "none" as the active media type.
1998-08-12 20:56:34 +00:00
thorpej a24f6f77bf Ugh, don't print out "autonegotiation failed to complete" if it did.
We get these once a second if we're in auto mode, the interface is up,
and there's no carrier.
1998-08-12 20:46:47 +00:00
thorpej f66f3b1ba9 Adapt to the new MII layer. This PHY driver now properly supports
802.3u autonegotiation, and will report the precise media selected
by autonegotiation by reading PHY-specific registers.

bouyer 10fcf021a5 Generic functions for the MII layer. mii attaches to mii-capable network
adapters, and provide media-selections and status to the parent.
This includes drivers for the Thunderland integrated PHY, and
National Semiconductor's DP83840A.
Note: The interface betweeen network controller and mii is not complete yet,
and will need some minors tweaks to support media auto-selection.
