I looked at the kernel source for this image (pointed to by Technologic Systems
tech support). In
linux24\net\bridge
there is the following Makefile:
#
# Makefile for the IEEE 802.1d ethernet bridging layer.
#
# Note! Dependencies are done automagically by 'make dep', which also
# removes any old dependencies. DON'T put your own dependencies here
# unless it's something special (ie not a .c file).
#
# Note 2! The CFLAGS definition is now in the main makefile...
O_TARGET := bridge.o
obj-y := br.o br_device.o br_fdb.o br_forward.o br_if.o br_input.o \
br_ioctl.o br_notify.o br_stp.o br_stp_bpdu.o \
br_stp_if.o br_stp_timer.o
obj-m := $(O_TARGET)
include $(TOPDIR)/Rules.make
----------
If I interpret this correctly, when the kernel is compiled with the -M option
it will produce bridge.o, which will contain all of the object files that would
be built into the kernel with the -Y option (namely, br.o, br_device.o, etc.).
I notice that no br_ioctl_hook.o or br_handle_frame_hook.o are included in this
list. Does this mean that some necessary dependencies were left out of
Technologic's build? The comment in the Makefile also mentions that
dependencies are automagically taken care of by 'make dep', so maybe more br_*
files were included in bridge.o than are listed in the Makefile.
