This is just a final note about this problem. I won't say it is
"solved" but at least we have a workaround.
This is from 4.10 release, src/dev/fxp/if_fxp.c, lines 509 et ff.
with the 'offending' code ifdef'd out by me:
/*
* Determine whether we must use the 503 serial interface.
*/
fxp_read_eeprom(sc, &data, 6, 1);
#ifndef BYPASS_503_SERIAL_CHECK
if ((data & FXP_PHY_DEVICE_MASK) != 0 &&
(data & FXP_PHY_SERIAL_ONLY))
sc->flags |= FXP_FLAG_SERIAL_MEDIA;
#else
sc->flags &= ~FXP_FLAG_SERIAL_MEDIA;
#endif
/*
* Create the sysctl tree
*/
When compiled and ran on an adlink motherboard (EBC-2000),
it now correctly IDs and configures the three fxp devices
on the motherboard:
fxp0: <Intel 82559 Pro/100 Ethernet> port 0xd400-0xd43f mem 0xe7200000-0xe72fffff,0xe7302000-0xe7302fff irq 11 at device 8.0 on pci0
fxp0: Ethernet address 00:30:64:01:86:ff
inphy0: <i82555 10/100 media interface> on miibus0
inphy0: 10baseT, 10baseT-FDX, 100baseTX, 100baseTX-FDX, auto
fxp1: <Intel 82559 Pro/100 Ethernet> port 0xd800-0xd83f mem 0xe7000000-0xe70fffff,0xe7301000-0xe7301fff irq 5 at device 9.0 on pci0
fxp1: Ethernet address 00:30:64:01:94:00
inphy1: <i82555 10/100 media interface> on miibus1
inphy1: 10baseT, 10baseT-FDX, 100baseTX, 100baseTX-FDX, auto
fxp2: <Intel 82559 Pro/100 Ethernet> port 0xdc00-0xdc3f mem 0xe7100000-0xe71fffff,0xe7300000-0xe7300fff irq 12 at device 10.0 on pci0
fxp2: Ethernet address 00:30:64:01:94:01
inphy2: <i82555 10/100 media interface> on miibus2
inphy2: 10baseT, 10baseT-FDX, 100baseTX, 100baseTX-FDX, auto
and I can 'ifconfig fxpN media xyz' between the supported
media types.
Once this project is shipped, I'll try and track down the
problem's root cause. This might still be a hardware issue
(the eeprom is being read wrong, or is not reporting capabilities
correctly, or ???).
Thanks to Simon Barner and others for helping out with the
OP.
