Lwip does not generate the FCS (aka CRC) at the end of the packet. The MAC does this. Also, the remote MAC will check it. An unless you specifically have changed your PC adapter settings (and have an adapter supporting this), you won't see the FCS in Wireshark. In fact, if you can see the packet in Wireshark, the FCS was good or your adapter would have thrown the packet away. There's an option in Wireshark (assume packets have FCS or something like that) to turn off the message.
