Use product_name

Do not assume that we ship uniprocessor kernel on LiveCD any longer.

When bdiff is detected in the filename, invoke the binary update
routines.

Make sure $d_fwupenabled_path is defined since it is initially defined
in guiconfig.inc. At some point in the future these variables should
be moved to globals.inc.

Automatically assume the embedded platform on update if the platform
is set to embedded or wrap. We do not include any kernels outside
of embedded anyways for this paticular platform.

• Do not allow the image to go read only during download / upgrade ops
• If a previous /root/firmware.tgz file exists before download, unlink
  the file to avoid a out of space error if the prior download operation
  happens to fail (or if / becomes rw again)

Remove any previous MD5 sums after upgrade.

Exit immediately after firmware update operation completes.

Add carriage return

Make $fp global

Do not close STDIN until script is done processing.

Prompt for kernel type if it is not defined.

Ticket #1435

Close STDIN ($fp) handle before returning back to shell. Major doh's.

Mount image read write before upgrading.

Mount read/write before fetching url.

Use unlink_if_exists()

Unlink upgrade file on upgrade.

Use /root/ as temporary storage.

Fetch the filesize initially and compare it. In addition we compare MD5 to be absolutely sure.

• Do not close a buffer that has failed
• Automatically retry failed connection

Exit if URL or PATH is blank.

Add md5 support if the site is storing the value.

Add firmware update menu option which can fetch a URL from the internet or use a already fetched file from the file system.
