Sorry, I don't have much experience with the Fixed PHY driver, but I
was under the impression that this is the sort of thing it was meant
for. Maybe someone at the Netdev list can help?

Re: MACB driver question

Hi all,

When I boot kernel with compiled-in Fixed PHY support on the board
with Micrel PHY I get:
MACB_mii_bus: probed
eth0: Atmel MACB at 0xfffc4000 irq 21 (00:00:00:00:00:00)
eth0: attached PHY driver [Fixed PHY] (mii_bus:phy_addr=ffffffff:01, irq=-1)

(Actually, this board works with generic phy support also very fine)

On the other hand, when booting the same kernel on the similar board
but without PHY (MAC in AT91SAM9260 connected directly with EtherCAT
ET1200 ASIC) I get:

MACB_mii_bus: probed
eth0: no PHY found

Kernel version is 2.6.24.3, part of .config:

CONFIG_FIXED_PHY=y
CONFIG_FIXED_MII_100_FDX=y
CONFIG_FIXED_MII_AMNT=1
CONFIG_NET_ETHERNET=y
CONFIG_MACB=y
