Commit Message

From: Petr Machata <petrm@nvidia.com>

The commit cited below moved code from net/forwarding/lib.sh to net/lib.sh,
and had the former source the latter. This causes issues with selftests
from directories other than net/forwarding/, in particular drivers/net/...
For those files, the line "source ../lib.sh" would look for lib.sh in the
directory above the script file's one, which is incorrect.

Instead, use $BASH_SOURCE and dirname to determine which directory the
forwarding/lib.sh resides in, and use that to find net/lib.sh.

Some selftests (namely drivers/net/bonding) use a symbolic link to
forwarding/lib.sh, and source that instead. Therefore pass $BASH_SOURCE
through readlink to resolve to the ultimate file.

Fixes: 25ae948b4478 ("selftests/net: add lib.sh")
