IEEE 802.3 Annex 28B.3 specifies the following relative
priorities of the technologies supported by
802.3 Selector Field value:
1000BASE-T full duplex
1000BASE-T
100BASE-T2 full duplex
100BASE-TX full duplex
100BASE-T2
100BASE-T4
100BASE-TX
10BASE-T full duplex
10BAST-T
Our drivers give 100BASE-T4 a higher priority than
100BASE-TX full duplex.
Fix this. This patch is based on changes in FreeBSD and OpenBSD.
Patch presented on tech-kern and tech-net:

ID pair. Misuse of the revision numbers was causing some of the chip
features to be disabled on some integrated Intel chips. So, move the
determination of the features into the bus frontend, where the
vendor/product ID is known. (Note: sc_rev should be removed. The
microcode patch stuff is also busted and needs to be fixed.) Also,
poll the actual flow control status in inphy, rather than making
assumptions.

- reset autonegotation timer if media option is not IFM_AUTO or we got a invalid link.
- Announce link loss right after it happens.
- Autonegotiation is retried every mii_anegticks seconds.
- Report link state changes right after setting autonegotiation.
- use rgephy_reset consistently
- change rgephy_reset to use mii_phy_reset and rgephy_load_dspcode.
These changes give me a speedup from 6.5MB/s to 9.1MB/s on a 100MBit link.
This delay cause 500us loops under splnet() per linkdown port per mii_tick.
It causes periodically drop packets. It's not acceptable for other devices.
Move gphyter and nsphyter specific delay(500) into the drivers from
mii_physubr.c.

service routine. Add a wrapper for PHY_SERVICE(), called phy_service(),
and check device_is_active() there. Make the mii_*() routines call
the PHY service routines thorugh phy_service() instead of PHY_SERVICE().
In mii_phy_resume(), restore a PHY's state after resetting it by
sending a MII_MEDIACHG command. This change makes bnx(4) resume
more reliably and more quickly; it should help other NICs to resume,
too, if they attach PHYs through MII.
