It seem is has +been changing during the time. Luckily its format seems to be backward +compatible starting with v2 (the only breakage was v1 -> v2). + +The version that was supported by brcmfmac so far was v4. It was what +43602a1 and 4366b1 firmwares (7.35.177.56 and 10.10.69.3309 accordingly) +were using. It also seems to be used by early 4366c0 firmwares +(10.10.69.6908 and 10.10.69.69017). + +The problem appears when switching to the 10.10.122.20 firmware. It uses +v5 and instead of falling back to v4 when submitted buffer isn't big +enough it fallbacks to the v3. + +To receive all v4 specific info with the newest firmware we have to +submit a struct (buffer) that matches v5. + +Signed-off-by: Rafał Miłecki <rafal@milecki.pl> +Acked-by: Arend van Spriel <arend.vanspriel@broadcom.com> +Signed-off-by: Kalle Valo <kvalo@codeaurora.org> +--- + .../net/wireless/broadcom/brcm80211/brcmfmac/fwil_types.h | 14 ++++++++++++++ + 1 file changed, 14 insertions(+) + +--- a/drivers/net/wireless/broadcom/brcm80211/brcmfmac/fwil_types.h ++++ b/drivers/net/wireless/broadcom/brcm80211/brcmfmac/fwil_types.h +@@ -174,6 +174,8 @@ + #define BRCMF_MFP_CAPABLE 1 + #define BRCMF_MFP_REQUIRED 2 + ++#define BRCMF_VHT_CAP_MCS_MAP_NSS_MAX 8 ++ + /* MAX_CHUNK_LEN is the maximum length for data passing to firmware in each + * ioctl.
