--0000000000007938ba0616b5fda8 Content-Type: text/plain; charset="UTF-8" Still working on the HW key/encryption/decryption support under the `LKPI_80211_HW_CRYPTO` block. - This week I was still testing the key setup paths to see any clue that leads to HW crypto offload malfunction. But as I was stuck with some dead ends, I took one day off last Friday to refresh my jammed brain. 1. I dumped more key setup traces with key contents. But all these traces confirm the key setup progress in firmware (Linux vs. FreeBSD) is correct. 2. Also the way how a ucast key is used in the TX path is verified again. Today, adrian@ and I took several hours debugging the code and analyzing different code paths. Also there is email discussion with Johannes Berg that adrian@ helped to reach out with. -- Best Regards, Cheng Cui --0000000000007938ba0616b5fda8 Content-Type: text/html; charset="UTF-8" Content-Transfer-Encoding: quoted-printable <div dir=3D"ltr">Still working on the HW key/encryption/decryption support = under the `LKPI_80211_HW_CRYPTO` block.<div><br></div><div><ul><li style=3D= "margin-left:15px">This week I was still testing the key setup paths to see= any clue that leads to HW crypto offload malfunction.
