From IRC:
05:25 < nbd> i'm currently working on 802.11->802.3 decap offload
05:25 < nbd> will try to take care of that patch afterwards
05:27 < nbd> i will work on that as well
05:27 < nbd> pablo will send our work on NAT offload (with my rewritten driver for MTK) upstream soon
05:28 < nbd> once that's in the tree, i can build on that for eth<->wifi offload
05:29 < nbd> it will be supported for mt7622 on the SoC side and 7915 for wifi
05:29 < nbd> maybe also 7615 later, not sure how much offload that one supports
05:30 < nbd> either way, 7915 will be the first wifi chip to have upstream eth<->wifi offload support
05:30 < nbd> for 1500 byte sized packets, the difference between SW and HW is small
05:31 < nbd> for smaller packets, offload will help
05:31 < nbd> sw performance is currently around 1700-1800 mbit/s under ideal conditions
05:32 < nbd> but still lower when sending to more stations at the same time
05:32 < nbd> not sure how much of that is sw limitation
05:33 < nbd> 4x4 80 MHz
05:33 < nbd> or 2x2 160 MHz
05:35 < rsalvaterra> nbd: You mean encapsulation offloading?
05:36 < nbd> rsalvaterra: nope
05:36 < nbd> encap offload is already done
05:36 < nbd> so i'm working on decap now
05:38 < nbd> the hw supports it, not sure how much of the code for it is upstream
05:38 < nbd> when i worked on the patch, only ath11k had upstream support
08:16 < dengqf6> nbd: Hauke: what about mt7621?
