Make docker bind the TFTP server to the correct interface
With UDP, docker sometimes can't route UDP packets to the correct address because the source address gets mangled [1]. This happens indeterministically because by default the kernel uses some heuristics to decide which interface to use. But in some rare circumstances, those can fail and a wrong source address is used. This can be worked around by explicitly binding to a concrete interface instead of 0.0.0.0.
