Some MDNS packets lead to Unsupported transport protocol (IDFGH-13632)

[archef2000]

Some packets get corrupted during ip6_input processing. The bottom of these packets are kept but the top where the UDP hdr is is overwritten.
I have printed the packet on line 1067 of ip6.c

Left is a wireshark capture of that packet.

Oh sorry. I forgot about the issue and fixed it in the winter break. The issue was here: https://github.com/archef2000/esp-owl/blob/923800ce04a96955956e5477b9945c76a06838aa/main/wifi/capture.c#L430 So the memory got freeed and the used by the netif.
