I don't have the whole context for this thread but I think I'm
following that the question is why MAC address pass thru isn't
activating on DS1000?
The criteria that we previously put in for this patch is still the
correct criteria; R8153-AD with a particular eFuse blown.
I never heard DS1000 is supposed to meet that criteria. I thought
official documentation referred to TB16 and WD15 only for Mac passthrough.
FYI I'm on holiday right now so it might take me some time to get back
after this response.
Some online shops selling the DS1000 mention it supports Mac Address
pass-through, for example:
https://shop.bechtle.de/medias/VXav7KboWIcl8FlvCBYV58-30.pdf
https://www.amazon.com/Dell-USB-Type-Monitor-Release-VT96R/dp/B01G6VL3I4/ref=sr_1_1?ie=UTF8&qid=1542809915&sr=8-1&keywords=DS1000
But actually, this might be a wrong information.
Sorry for the noise if this is the case, and too bad the DS1000 does not
support pass-through.
