Hi Yongho, Thanks for your clarification. I give the example of 4-address format just to clarify my point that each MAC address has it’s own business, we should not encourage to reuse them for other purpose unless we have a wonderful corresponding
solution. Could you explain the following question? I have reviewed your presentation just now, but I don’t find the solution. As you know, it’s need to convert 802.11 header to 802.3 header before deliver the MSDU to network stack. Following your SP, how to covert the SA and DA field in 802.3 header on both 11be STA and legacy STA? Do you intend to use MLD MAC which is reused as SA to fill the SA field in 802.3 header?
Thanks Best Regards Jay Yang From: Yongho Seok <yongho.seok@xxxxxxxxx> Hi Jay, You are just misunderstanding the SP. The SP didn't say that the A3 field is set to the MLD MAC address. It said that the SA field is set to the MLD MAC address. An AP MLD that broadcasts the group addressed MPDU received from a non-AP MLD with which it has done multi-link setup shall set
the SA field of the broadcast group addressed MPDU to the MLD MAC address of the non-AP MLD. A non-AP MLD filters out the group addressed MPDU with
the SA field set to the MLD MAC address of the non-AP MLD. You made an issue with a wrong example. In your example, the 4-address format contains the SA in the A4 field. If needed, the SP said that the A4 field is set to the MLD MAC address. >> BTW, I understand the A3 used to indicate DA in SPEC, not SA, could you double confirm it? This is wrong. The content of the A3 field is varied depending on the MSDU type and the UL/DL. When an AP sends a group-address frame, the A3 field is set to the SA field. Regards, Yongho 2020년 8월 31일 (월)
