IEEE 802.3 Annex 28B.3 explicitly 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 However PHY drivers did not honor the order such that 100BASE-T4 had higher priority than 100BASE-TX full duplex. Fix a long standing bug such that PHY drivers choose the highest common denominator ability. This bug is exposed by a Cisco 3550 switch which inadvertently announces 100BASE-T4 capability even though it is not capable of 100BASE-T4 operation, it is a 100BASE-TX switch. From FreeBSD Tested with dc(4), fxp(4), rl(4), sis(4).
