stable inclusion from stable-v6.6.2 commit 8df43e3477e986bf687bd64fdf4f79fc8dea618a category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I8IW7G
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=...
--------------------------------
[ Upstream commit 63ef576c9facf5d92702e249ad213fa73eb434bf ]
We don't (yet) send the IGTK down to the firmware, but when we do it needs to be with the broadcast station ID, not the multicast station ID. Same for the BIGTK, which we may send already if firmware advertises it (but it doesn't yet.)
