fix media priorities
Hi,
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.
Attached patch fixes this.
(Patch is based on changes in FreeBSD and OpenBSD)
I wrote this patch in consequence of PR 40586.
Comments ?
