Batch delete uci options refactor
There are pretty much similar for loops on deleting bunch of uci options in wan
module like:
for field in ["ip6prefix", "ip6addr", "ip6gw"]:
backend.del_option("network", "wan6", field, fail_on_error=False)
it may be neat to lose some 5+ lines on this to use helper function in Uci class like:
def _uci_del_batch(config: str, section_name: str, options: List[str]):
for option in options:
backend.del_option(config, section_name, option, fail_on_error=False)
similar to #172 (closed)
