bpf/skb: Fix netcap load fail in some kernel verison #10

Closed zf1575192187 closed 1 month ago

Error log: R2 unbounded memory access, use 'var &= const' or 'if (var < const)'.

The reason is that some variable types are inconsistent, and the min and max attribute is lost after type conversion, resulting bpf load failed.
