Not true, it reveals that I forgot to put it in the patch, that's all. As
I cannot run several of these tests because of memory constraints I link
the file to a copy in a rw area where I modify the list and just run one
of the subtests at a time. If I try to run the whole it always fails
after a couple of sub-tests with an error.

It seems to me that these scripts are quite memory consuming as they
accumulate memory consuption in relation to what is loaded along the
way. A major problem with my system.

I'm sorry for perhaps asking something entirely obvious, but have you tried:

kernel-dir $ rsync -avr tools/testing/selftests/ root@$board:selftests/
board $ cd selftests/drivers/net/dsa/
board $ ./bridge_locked_port.sh lan0 lan1 lan2 lan3

?

This is how I always run them, and it worked fine with both Debian
(where it's easy to add missing packages to the rootfs) or with a more
embedded-oriented Buildroot.

The memory problems are of course on the embedded target. In that case I
think it would be a very good idea to do something to design the system
better, so that it frees memory between the subtests.

If all tests are always run on the bridge only, I think they don't make
much sense as these patchsets are directed towards switchcores.
