From c97ab504419b41e8bcc2ade6b9b02a32ab626296 Mon Sep 17 00:00:00 2001 From: Vasily Khoruzhick Date: Tue, 7 Mar 2023 23:17:30 +0100 Subject: Bluetooth: Add new quirk for broken local ext features page 2 [ Upstream commit 8194f1ef5a815aea815a91daf2c721eab2674f1f ] Some adapters (e.g. RTL8723CS) advertise that they have more than 2 pages for local ext features, but they don't support any features declared in these pages. RTL8723CS reports max_page = 2 and declares support for sync train and secure connection, but it responds with either garbage or with error in status on corresponding commands.
