Doh... :-(
I've played with this a bit, and I noticed that if you do:
$ git clean -dX; git clean -d # Make sure tree is clean
$ make allmodconfig
$ grep PHYLIB= .config
CONFIG_PHYLIB=m
$ make menuconfig
Device Drivers -->
Network device support -->
-*- PHY Device support and infrastructure -->
Notice how "PHY Device support and infrastructure" is forced to 'y', not
'm'. This is expected, because it is selected by (there are other terms
in the equation that also force it to 'y'):
ETHOC [=y] && NETDEVICES [=y] && ETHERNET [=y]
&& HAS_IOMEM [=y] && HAS_DMA [=y]
Hence, what we see is that "make allmodconfig" does not properly resolve
the symbols values.
I'll tackle this, but it may take some time...

Yann E. MORIN.
