chip revision often found in the blades and resulting in interfaces
not sensing carrier signal. Looking at all problem reports it
appears that it only affects some very specific silicon revision
(ASIC (0x57081021); Rev (B2)) and version of the PHY that
supports 1000baseSX-FDX media only. Therefore, narrow the scope of
workaround to combination of that revision and media type. Given
that the first report on this issue is dated back to 2007, there is
not much hope that this issue will ever be properly resolved.
Among affected systems are IBM HS21, Intel SBXD132 and HP BL460c.

Also report current link state while auto-negotiation is in

With this change link loss should be reported within a second
and drivers that rely on link state should work.

They also do not have an EEPROM, so the MAC address must be read from

- Moved BCM5706S/5708S SerDes support to brgphy (since they are not technically
TBI interfaces)
- Added 2.5G support for BCM5708S
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.

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.
