[Qemu-devel] [PATCH for-2.8? 3/3] block/curl: Drop TFTP "support"

[Max Reitz <mreitz@redhat.com>]

Because TFTP does not support byte ranges, it was never usable with our
curl block driver. Since apparently nobody has ever complained loudly
enough for someone to take care of the issue until now, it seems
reasonable to assume that nobody has ever actually used it.

Therefore, it should be safe to just drop it from curl's protocol list.
