[PATCH] tplink-safeloader: fix C7v5 factory flashing from vendor fw > v1.1.x

[Henrique de Moraes Holschuh]

Any updates on this?

An user reported to us this same issue with the latest 2021 version of 
the C7v5-US tp-link firmware [as available in Brazil].

Install was possible only through tftp: the tp-link stock firmware web 
page would refuse the factory image.
