Hi all,

Frantisek linked my work on AQL here. This is my first post on these
lists. I am the author of the OpenWrt PR he linked and of the ath11k
AQL patches.

I wanted to share that, with the help of AI, I was able to build a PPE
hardware offload driver for IPQ8074/IPQ6018:

https://github.com/openwrt/openwrt/pull/24806

The exciting part of the implementation is the PPE flow tables, port
shapers and queue classifiers.

Jie Luo from Qualcomm confirmed on the netdev list that even Qualcomm
themselves do not have these advanced features internally:

Initial bring-up of the less advanced parts, NAT, PPPoE and the like,
took roughly a weekend.

Julius
