Fetch the new capture with

 wget -O pcap2.zip http://ge.tt/api/1/files/136167y/0/blob?downlad


The capture[1] shows two[2] TFTP transmissions of sles113/syslinux.efi,
but nothing after that. As if syslinux.efi was crashed.

Notes
[1] With a snaplength of 96 bytes or something.
    Add -S0 to tcpdump to get the full network packets.
[2] A previous posting says that the repeated transmission
    is an artifact of the firmware.
