From: Sean Wang <sean.wang@xxxxxxxxxxxx> Introduce mt7615_mcu_uni_set_bss, mt7615_mcu_uni_set_dev and mt7615_mcu_uni_set_beacon_offload uni mcu commands. This is a preliminary patch to add mt7663e support Signed-off-by: Sean Wang <sean.wang@xxxxxxxxxxxx> Co-developed-by: Lorenzo Bianconi <lorenzo@xxxxxxxxxx> Signed-off-by: Lorenzo Bianconi <lorenzo@xxxxxxxxxx> --- .../net/wireless/mediatek/mt76/mt7615/mcu.c | 205 ++++++++++++++++++ .../net/wireless/mediatek/mt76/mt7615/mcu.h | 7 + 2 files changed, 212 insertions(+) diff --git a/drivers/net/wireless/mediatek/mt76/mt7615/mcu.c b/drivers/net/wireless/mediatek/mt76/mt7615/mcu.c index b0c226cc0528..93f6fa9dafb6 100644 --- a/drivers/net/wireless/mediatek/mt76/mt7615/mcu.c +++ b/drivers/net/wireless/mediatek/mt76/mt7615/mcu.c @@ -1105,6 +1105,207 @@ static const struct mt7615_mcu_ops sta_update_ops = { .sta_add = mt7615_mcu_add_sta, }; +static int +mt7615_mcu_uni_add_dev(struct mt7615_dev *dev, + struct ieee80211_vif *vif, bool enable) +{ + struct mt7615_vif *mvif = (struct mt7615_vif *)vif->drv_priv; + struct { + struct req_hdr { + u8 omac_idx; + u8 band_idx; + __le16 pad; + } __packed hdr; + struct req_tlv { + __le16 tag; + __le16 len; + u8 active; + u8 pad; + u8 omac_addr[ETH_ALEN]; + } __packed tlv; + } data = { + .hdr = { + .omac_idx = mvif->omac_idx, + .band_idx = mvif->band_idx, + }, + .tlv = { + .tag = cpu_to_le16(DEV_INFO_ACTIVE), + .len = cpu_to_le16(sizeof(struct req_tlv)), + .active = enable, + }, + }; + + memcpy(data.tlv.omac_addr, vif->addr, ETH_ALEN); + + return __mt76_mcu_send_msg(&dev->mt76, MCU_UNI_CMD_DEV_INFO_UPDATE, + &data, sizeof(data), true); +} + +static int +mt7615_mcu_uni_ctrl_pm_state(struct mt7615_dev *dev, int band, int state) +{ + return 0; +} + +static int +mt7615_mcu_uni_add_bss(struct mt7615_dev *dev, + struct ieee80211_vif *vif, bool enable) +{ + struct mt7615_vif *mvif = (struct mt7615_vif *)vif->drv_priv; + struct { + struct req_hdr { + u8 bss_idx; + u8 pad[3]; + } __packed hdr; + struct basic_tlv { + __le16 tag; + __le16 len; + u8 active; + u8 omac_idx; + u8 hw_bss_idx; + u8 band_idx; + __le32 conn_type; + u8 conn_state; + u8 wmm_idx; + u8 bssid[ETH_ALEN]; + __le16 bmc_tx_wlan_idx; + __le16 bcn_interval; + u8 dtim_period; + u8 phymode; + __le16 sta_idx; + u8 nonht_basic_phy; + u8 pad[3]; + } __packed basic; + } req = { + .hdr = { + .bss_idx = mvif->idx, + }, + .basic = { + .tag = cpu_to_le16(UNI_BSS_INFO_BASIC), + .len = cpu_to_le16(sizeof(struct basic_tlv)), + .bcn_interval = cpu_to_le16(vif->bss_conf.beacon_int), + .dtim_period = vif->bss_conf.dtim_period, + .omac_idx = mvif->omac_idx, + .band_idx = mvif->band_idx, + .wmm_idx = mvif->wmm_idx, + .active = enable, + }, + }; + u8 idx, tx_wlan_idx = 0; + + idx = mvif->omac_idx > EXT_BSSID_START ?
