RE: [EXTERNAL] Re: [PATCH] Revert "wlcore: Adding suppoprt for IGTK key in wlcore driver"

["Bouganim, Raz" <r-bouganim@ti.com>]

We are going to release a new FW version 8.9.0.0.83 that contains support with the new IGTK key.

In addition, we also going to release a new patch that mandates the driver to work with an 8.9.0.0.83 FW version or above.

We going to push it today/tomorrow.

[PATCH] wl18xx: Update the latest firmware supported
This patch mandates the driver to work with an 8.9.0.0.83 FW version or above.
This is to fix a kernel panic caused by establishing a PMF/WPA3 connection with older FW versions.

You can get the latest firmware at:
git://git.ti.com/wilink8-wlan/wl18xx_fw.git

Any updates? If I don't hear anything I will just queue this to v5.9.

Reminder to myself: remove Mauro's duplicate s-o-b tag, that's a patchwork bug
