It looks like pmtu.sh was not converted in patch set [1], so it doesn't
have "source lib.sh" yet. The cover letter of [1] mentions that the
whole process of conversion will be split into several parts. Not sure
if pmtu.sh will be converted in the subsequent parts soon? If so, would
you like to change the shebang of pmtu.sh when converting it later, or
change it together in this patch? Thanks.

BTW, in addition to pmtu.sh, I noticed that there are several other
scripts in net selftests which have "/bin/sh" shebang:

linux/tools/testing/selftests/net$ grep -rF '#!/bin/sh'
openvswitch/openvswitch.sh:#!/bin/sh
in_netns.sh:#!/bin/sh
netdevice.sh:#!/bin/sh

Sure, will respin a v2 with this change added.

Thanks,
