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 +@@ -165,6 +165,8 @@ + #define BRCMF_MFP_NONE 0 + #define BRCMF_MFP_CAPABLE 1 + #define BRCMF_MFP_REQUIRED 2 ++ ++#define BRCMF_VHT_CAP_MCS_MAP_NSS_MAX 8 + + /* join preference types for join_pref iovar */ + enum brcmf_join_pref_types { +@@ -514,6 +516,8 @@ struct brcmf_sta_info_le { + /* w/hi bit set if basic */ + __le32 in; /* seconds elapsed since associated */ + __le32 listen_interval_inms; /* Min Listen interval in ms for STA */ ++ ++ /* Fields valid for ver >= 3 */ + __le32 tx_pkts; /* # of packets transmitted */ + __le32 tx_failures; /* # of packets failed */ + __le32 rx_ucast_pkts; /* # of unicast packets received */ +@@ -522,6 +526,8 @@ struct brcmf_sta_info_le { + __le32 rx_rate; /* Rate of last successful rx frame */ + __le32 rx_decrypt_succeeds; /* # of packet decrypted successfully */ + __le32 rx_decrypt_failures; /* # of packet decrypted failed */ ++ ++ /* Fields valid for ver >= 4 */ + __le32 tx_tot_pkts; /* # of tx pkts (ucast + mcast) */ + __le32 rx_tot_pkts; /* # of data packets recvd (uni + mcast) */ + __le32 tx_mcast_pkts; /* # of mcast pkts txed */ +@@ -558,6 +564,14 @@ struct brcmf_sta_info_le { + */ + __le32 rx_pkts_retried; /* # rx with retry bit set */ + __le32 tx_rate_fallback; /* lowest fallback TX rate */ ++ ++ /* Fields valid for ver >= 5 */ ++ struct { ++ __le32 count; /* # rates in this set */ ++ u8 rates[BRCMF_MAXRATES_IN_SET]; /* rates in 500kbps units w/hi bit set if basic */ ++ u8 mcs[BRCMF_MCSSET_LEN]; /* supported mcs index bit map */ ++ __le16 vht_mcs[BRCMF_VHT_CAP_MCS_MAP_NSS_MAX]; /* supported mcs index bit map per nss */ ++ } rateset_adv; + }; + + struct brcmf_chanspec_list { |
