Nevertheless, as the udp frame seem to be received by the target, I
don't think this is the problem for sending an udp frame from the
embedded lwIP to my linux station.
Could it be the checksum error?
User Datagram Protocol, Src Port: 41486 (41486), Dst Port: tftp (69)
Source port: 41486 (41486)
Destination port: tftp (69)
Length: 13
Checksum: 0x3333 [incorrect, should be 0x419b (maybe caused by "UDP checksum offload"?)]
[Good Checksum: False]
[Bad Checksum: True]
Trivial File Transfer Protocol
Opcode: Unknown (28777)
Data (3 bytes)
