>Description:
I cant't compile kernel without ethernet devices.

After "make depend":
../../../../net/if_ethersubr.c:107:2: #error You have included NETATALK or a pseudo-device in your configuration that depends on the presence of ethernet interfaces, but have no such interfaces configured. Check if you really need pseudo-device bridge, pppoe, vlan or options NETATALK.
mkdep: compile failed.
*** Error code 1

Stop.
make: stopped in /usr/src/sys/arch/i386/compile/WODOGRZMOT.TEST

>How-To-Repeat:
Remove all ethernet devices from a kernel config file and try to recompile a kernel.
