hi all:
we found some common using issues about the use of CLI unformat, as follow:
u16 out_port = 0
u32 vrf_id = 0, protocol
else if (unformat (line_input, "%U %u", unformat_ip4_address,
&out_addr, &out_port))
when inputing u16 or u8 type param(not u32)， the local variable which behind
of "out_port" in stack will be overwrited, is that right? is there some Notes
about this?
I think the bellow code maybe cause that issue.
unformat->va_unformat->do_percent->unformat_integer-> *(u32 *) v = value
