This patch adds a new explicit Floppy Drive Type option. The existing behavior in QEMU is to automatically guess a drive type based on the media inserted, or if a diskette is not present, arbitrarily assign one. This behavior can be described as "auto." This patch adds the option to pick an explicit behavior: 120, 144, 288 or none. The new "auto" option is intended to mimic current behavior, while the other types pick one explicitly. Set the type given by the CLI during fd_init. If the type remains the default (auto), we'll attempt to scan an inserted diskette if present to determine a type. If auto is selected but no diskette is present, we fall back to a predetermined default (currently 1.44MB to match legacy QEMU behavior.)
