[9fans] vgbe: no phy found

[9fans] vgbe: no phy found

[Richard Miller]

While booting I get this sequence of messages:

    vgbe: miir timeout
    vgbe: no phy found
    #l1: vgbe: 1000Mbps port 0xD400 irq 5: 00e08155866a

The last line implies that this interface has been configured, but
when I attempt to send packets on it, no interrupt is received.  So
I suspect the "missing" phy is fatal.

Should ethervgbe abort the pnp sequence when no phy is found, as
for example ethervt6102 does?

Is there anything I can try in order to get this interface working?
It's a built-in interface on a VIA VT310 board.

Hello Richard,

    I encountered such problem once, when I worked on this driver, but it
disappeared after I've booted to FreeBSD. I think the phy initialization
code I wrote needs to be enhanced. Indeed it seems (from the FreeBSD
sources) that some phys are bugged and need to be inited with special
sequence. I would suggest you to check first if your board has such phy.

    Regards,
    Phil.

I think we can also simply enhance mii.c source in order to handle such 
thing.
Indeed such phys can be used with other network chips.

According to this message, it seems to be broken in FreeBSD now too:
