building module regression

[Paul B. Mahol]

Hello

With latest kernel it is no more possible
to do something like this (with net drivers):

# cd /sys/modules/mii && make

In file included from @/net/if_var.h:723,
                 from @/net/if.h:458,
                 from /usr/src/sys/modules/mii/../../dev/mii/acphy.c:82:
@/net/vnet.h:36:23: error: opt_route.h: No such file or directory
*** Error code 1

Stop in /usr/src/sys/modules/mii

It is introduced once ifdef VIMAGE are removed from net/vnet.h in
185419 revision.
