Thank you for the updated patch!

In create_patch(), || is treated as if it yields the first nonzero
value, but actually in C it always yields 0 or 1, so this will squash
all errno values to 1 (EPERM as it happens on Linux).

In setup_patch(), if you do care about unknown arguments, you could
check for shash_count(args) > 1.

In setup_patch(), I think that IFNAMSIZ - 1 would be a more accurate
maximum device name length, because IFNAMSIZE has to include the
trailing null byte.
