Bluetooth: btusb: QCA: Fix downloading wrong NVM for WCN6855 GF variant without board ID

2025-07-24T06:58:37+00:00

[ Upstream commit 43015955795a619f7ca4ae69b9c0ffc994c82818 ]

For GF variant of WCN6855 without board ID programmed
btusb_generate_qca_nvm_name() will chose wrong NVM
'qca/nvm_usb_00130201.bin' to download.

Fix by choosing right NVM 'qca/nvm_usb_00130201_gf.bin'.
Also simplify NVM choice logic of btusb_generate_qca_nvm_name().

Bluetooth: hci_dev: replace 'quirks' integer by 'quirk_flags' bitmap

in future. Replace raw bit operations by accessor macros.

Bluetooth: btintel: Check if controller is ISO capable on btintel_classify_pkt_type

2025-07-24T06:58:28+00:00

commit 6ec3185fbc3528f2284c347fb9bd8be6fa672ed4 upstream.

Due to what seem to be a bug with variant version returned by some
firmwares the code may set hdev->classify_pkt_type with
btintel_classify_pkt_type when in fact the controller doesn't even
support ISO channels feature but may use the handle range expected from
a controllers that does causing the packets to be reclassified as ISO
causing several bugs.

To fix the above btintel_classify_pkt_type will attempt to check if the
controller really supports ISO channels and in case it doesn't don't
reclassify even if the handle range is considered to be ISO, this is
considered safer than trying to fix the specific controller/firmware
version as that could change over time and causing similar problems in
the future.
