I just did a full test with the intention of merging it into
master, and I noticed it causes new warnings on the sparc
prom tests:
TEST: tests/prom-env-test... (pid=17171)
/sparc/prom-env/SPARCbook:
Warning: nic
lance.0 has no peer
OK
/sparc/prom-env/Voyager:
Warning: nic
lance.0 has no peer
OK
/sparc/prom-env/SS-20:
Warning: nic
lance.0 has no peer
OK
PASS: tests/prom-env-test
So it needs some tweaking, I think.
thanks
