The linked lede-17.01.4-ar71xx-generic-tl-wr2543-v1-squashfs-factory.bin is definately not a D-Link firmware in disguise, so you're either dealing with browser cache issues from your browser or flashed a wrong firmware (not distributed by LEDE). Clear your browser cache first and try to gain access via ssh (or telnet to your router) - and make sure that you've really connected to the correct device.
Assuming you're really running the D-Link firmware (which would be close to impossible, given that the D-Link DIR-100 is a completely different SOC, even a different arch), you might still have a chance to recover via tftp (if that's available depends on the version of the previously installed OEM firmware, as it was only retrofitted to their firmware's bootloader after they had already EOLed the hardware) - otherwise there might still be an option via serial console.
If you'd ask me, I'd bet that you didn't actually wire up your TP-Link TL-WR2543ND, but somehow reached that DIR-100 via a different way (wrong cable, wlan, IP address conflict, stale browser cache, etc.).
The problem was actually something with the chrome, I cleared the cache and accessed again entered the LEDE screen.
Now I honestly do not know why this D-LINK screen appeared and I never had or configured a DLINK on my computer ...
