With this change several NVIDIA ethernet controllers(e.g. MCP61)
works.
RTL8211B(L) is RealTek's new gigabit PHY. The PHY has several
features including crossover correction, polarity correction as
well as supporting triple speed(10/100/1000bps). Data transfer
between MAC and PHY is via RGMII for 1000baseT, MII for
10baseT/100baseTX.
Unfortunately, RealTek used the same model number for RTL8211B(L)
PHY so there is no way to discriminate between RTL8211B(L) and its
predecessors. ATM RTL8211B uses revision number 2 so checking the
revision number seems to be only way to identify it.

autonegotiation process at 1000bps.
o Reset autonegotation timer if media option is not IFM_AUTO or we
got a valid link.
o Announce link loss right after it happends.
o Autonegiation is retried every mii_anegticks seconds.

- Moved BCM5706S/5708S SerDes support to brgphy (since they are not technically

Comments:
Since this driver is shared with bge I tested several available controllers
supported by bge and all worked as expected, however the list was not
exhaustive. Need wider testing.

also avoids problems when a function pointer doesn't have the
same width as a void pointer.
sc->mii_anegticks according to whether the respective BGE chip
supports Fast Ethernet only or also Gigabit Ethernet.
- At least the BGE chips I've tested with wedge when isolating them
so document this as the reason for setting MIIF_NOISOLATE and
remove the unused (and partially even #ifdef'ed out) isolation
related code. Add code that panics if we encounter a non-zero MII
instance as generally there's no way a PHY requiring MIIF_NOISOLATE
can be handled gracefully in a multi-PHY configuration (it's ok for
the internal PHY of single-PHY-only-NIC to not support isolation
though).
- Additionally set MIIF_NOLOOP as loopback doesn't seem to work
either and remove the #ifdef'ed out code for adding respective
media. The MIIF_NOLOOP flag currently triggers nothing but
hopefully will be respected by mii_phy_setmedia() later on.

addition of SerDes support. According to the docs, the 5706C and 5708C
phys are supposed to use the same MII model that is separate from the
SerDes parts, but the 5706C actually uses the MII model of the SerDes
parts. To fix this, readd the old 5706C entry to miidevs and add a
special check in brgphy_probe() for phys that match the 5706C ID. If
the phy is supported by the gentbi(4) driver, then it's a SerDes phy, so
we fail the probe and let gentbi(4) grab it. Otherwise, it's a 5706C phy,
so we let brgphy(4) grab it.

Bugfix for the Realtek PHY driver... an RTL8201L standalone PHY
needs different handling than the integrated ones in terms of
speed detection. There was a bogus test based on the parent
device driver name string controlling which speed register to
query. That test began failing when the rl driver was split into
separate rl and re drivers some time ago. Apparently nobody ever
noticed because the buggy code only executes if NWAY negotiation
failed. Since we happen to be testing with an ancient dumb hub
rather than a modern switch, we found it.
To fix it all, have the attach() routine notice whether we're
dealing with an integrated PHY or an RTL8201L and store that info
in a struct accessible to the status() routine that needs to know
which register to query.
I touched up the fixes because they were relative to RELENG_6 and to
bring a few nits into line with style(9).

ifmedia_init() invocation. IFM_IMASK makes only sense here when all of
the maxium of 32 PHYs on each one MII bus support disjoint sets of media,
which generally isn't the case (though it would be nice if we had a way
to let NIC drivers indicate that for the few card models where the PHY
configuration is known/fixed and IFM_IMASK actually makes sense).
- Add and use a miibus_print_child() for the bus_print_child method which
additionally prints the PHY number (which actually is the PHY address)
so one can figure out the media instance <-> PHY number mapping from the
PHY driver attach output. This is intented to be usefull in situations
where the addresses of the PHYs on the bus are known (f.e. of internal/
integrated PHYs) so one can feed the appropriate media instance number
to ifconfig(8) (with the upcoming change for ifconfig(8)).
This is more or less inspired by the NetBSD mii_print().

problems when isolating due to incomplete implementations or silicon bugs
we'll need to add specific drivers for these. Looking at NetBSD and
OpenBSD I don't expect problems here though (quite the contrary; we still
seem to set MIIF_NOISOLATE without good reason in a bunch of PHY drivers).

o Make manual media selection work for all supported media types.
o Don't set MIIF_NOISOLATE so e1000phy(4) can be used in

o In 1000baseT, when setting the link manually, one side must be the
master and the other the slave. If LINK0 is set, program the PHY
to be a master, otherwise it's a slave.
o When we lost a link, reset mii_ticks immediately so it correctly

o Announce link loss right after it happens.
o After kicking autonegotiation, report PHY status instead of
returning immediatly.
o When link state check is in progress, check auto negotiation

o When PHY is resolved to a master, show it with IFM_FLAG2.
