> The current WED only supports 256 wcid, whereas mt7986 can support up to 512 entries, > so firmware provides a rule to get sta_info by DA when wcid is set to 0x3ff by txd. > Also, WED provides a register to overwrite txd wcid, that is, wcid[9:8] can > be overwritten by 0x3 and wcid[7:0] is set to 0xff by host driver. > > However, firmware is unable to get sta_info from DA as DA != RA for 4addr cases, > so firmware and wifi host driver both use wcid (256 - 271) and (768 ~ 783) > for sync up to get correct sta_info > > Tested-by: Sujuan Chen <sujuan.chen@xxxxxxxxxxxx> > Co-developed-by: Bo Jiao <bo.jiao@xxxxxxxxxxxx> > Signed-off-by: Bo Jiao <bo.jiao@xxxxxxxxxxxx> > Signed-off-by: Sujuan Chen <sujuan.chen@xxxxxxxxxxxx> > --- > This patch is based on > https://patchwork.kernel.org/project/linux-mediatek/list/?series=697444 > --- > drivers/net/wireless/mediatek/mt76/mt76.h | 6 +++ > .../net/wireless/mediatek/mt76/mt7603/main.c | 2 +- > .../net/wireless/mediatek/mt76/mt7615/main.c | 2 +- > .../wireless/mediatek/mt76/mt7615/pci_init.c | 2 +- > .../wireless/mediatek/mt76/mt7615/usb_sdio.c | 2 +- > .../net/wireless/mediatek/mt76/mt76x02_util.c | 2 +- > .../net/wireless/mediatek/mt76/mt7915/init.c | 2 +- > .../net/wireless/mediatek/mt76/mt7915/main.c | 24 +++++++++-- > .../net/wireless/mediatek/mt76/mt7915/mcu.c | 11 ++++- > .../net/wireless/mediatek/mt76/mt7915/mcu.h | 1 + > .../net/wireless/mediatek/mt76/mt7915/mmio.c | 3 ++ > .../net/wireless/mediatek/mt76/mt7921/init.c | 2 +- > .../net/wireless/mediatek/mt76/mt7921/main.c | 2 +- > .../net/wireless/mediatek/mt76/mt7996/init.c | 2 +- > .../net/wireless/mediatek/mt76/mt7996/main.c | 2 +- > drivers/net/wireless/mediatek/mt76/util.c | 42 ++++++++++++++++++- > drivers/net/wireless/mediatek/mt76/util.h | 2 +- > 17 files changed, 91 insertions(+), 18 deletions(-) > Hi Sujuan, I took just a brief look at the patch, but I think you can significantly reduce the patch size doing something like: int __mt76_wcid_alloc(u32 *mask, int size, u8 flag) { ... } static inline int mt76_wcid_alloc(u32 *mask, int size) { return __mt76_wcid_alloc(, 0); } > diff --git a/drivers/net/wireless/mediatek/mt76/mt76.h b/drivers/net/wireless/mediatek/mt76/mt76.h > index 33f87e518d68..1763b582c020 100644 > --- a/drivers/net/wireless/mediatek/mt76/mt76.h > +++ b/drivers/net/wireless/mediatek/mt76/mt76.h > @@ -38,6 +38,12 @@ > #define MT_WED_Q_RX(_n) __MT_WED_Q(MT76_WED_Q_RX, _n) > #define MT_WED_Q_TXFREE __MT_WED_Q(MT76_WED_Q_TXFREE, 0) > > +enum mt76_wed_state { > + MT76_WED_DISABLED, > + MT76_WED_ACTIVE, > + MT76_WED_WDS_ACTIVE, > +}; > + > struct mt76_dev; > struct mt76_phy; > struct mt76_wcid; > diff --git a/drivers/net/wireless/mediatek/mt76/mt7603/main.c b/drivers/net/wireless/mediatek/mt76/mt7603/main.c > index ca50feb0b3a9..d788bb59a113 100644 > --- a/drivers/net/wireless/mediatek/mt76/mt7603/main.c > +++ b/drivers/net/wireless/mediatek/mt76/mt7603/main.c > @@ -347,7 +347,7 @@ mt7603_sta_add(struct mt76_dev *mdev, struct ieee80211_vif *vif, > int idx; > int ret = 0; > > - idx = mt76_wcid_alloc(dev->mt76.wcid_mask, MT7603_WTBL_STA - 1); > + idx = mt76_wcid_alloc(dev->mt76.wcid_mask, MT7603_WTBL_STA - 1, 0); > if (idx < 0) > return -ENOSPC; > [...] > mt76_connac_mcu_wtbl_update_hdr_trans(&dev->mt76, vif, sta); > } > > @@ -1448,15 +1462,19 @@ mt7915_net_fill_forward_path(struct ieee80211_hw *hw, > if (!mtk_wed_device_active(wed)) > return -ENODEV; > > - if (msta->wcid.idx > 0xff) > + if (msta->wcid.idx > MT7915_WTBL_STA) > return -EIO; > > path->type = DEV_PATH_MTK_WDMA; > path->dev = ctx->dev; > path->mtk_wdma.wdma_idx = wed->wdma_idx; > path->mtk_wdma.bss = mvif->mt76.idx; > - path->mtk_wdma.wcid = is_mt7915(&dev->mt76) ?
