If you consider for example the routines below: - mt76_connac*_mac_write_txwi_8023() - mt76_connac*_mac_write_txwi_80211() - mt76_connac*_mac_add_txs_skb() - mt76_connac*_txwi_free() - ... they are the same for mt7615/mt7663, mt7921/mt7915, mt7996/.. , what is changing is just register map between versions (e.g. mt7615/mt7663 and mt7915/mt7921). I think it is not a good idea to copy-paste the code because it will just make the code much harder to maintain, and this will be more difficult to address in the future. If you consider the commit below: commit ead449023d3acb1424886d7b8cc672ed69bdd27e Author: Lorenzo Bianconi <lorenzo@xxxxxxxxxx> Date: Sun May 28 12:28:49 2023 +0200 wifi: mt76: mt7996: fix possible NULL pointer dereference in mt7996_mac_write_txwi() Fix possible NULL pointer dereference on mvif pointer in mt7996_mac_write_txwi routine. Deren will needs to monitor the ML and apply the same fix for the other WiFi7 chipset too. Moreover I kept mt7996/mac.{c,h} to put the per-chipset codebase. If you think MT76_CONNAC3_BASIC_RATES_TBL11 and MT76_CONNAC3_BEACON_RATES_TBL25 are sensible, we can put them in mt7996/mac.h Regards, Lorenzo > > > > Thanks, > > Shayne > > > (Resend for missing CC) > > > > > > > > --- > > > > > > > drivers/net/wireless/mediatek/mt76/Makefile | 2 +- > > > > > > > .../net/wireless/mediatek/mt76/mt76_connac.h | 19 + > > > > > > > .../wireless/mediatek/mt76/mt76_connac3_mac.c | 742 > > > > > > > +++++++++++++++++ > > > > > > > .../wireless/mediatek/mt76/mt76_connac3_mac.h | 18 + > > > > > > > .../net/wireless/mediatek/mt76/mt7996/init.c | 4 +- > > > > > > > .../net/wireless/mediatek/mt76/mt7996/mac.c | 761 +----- > > > > > > > -- > > > > > > ---- > > > > > > > ---- > > > > > > > -- > > > > > > > .../net/wireless/mediatek/mt76/mt7996/main.c | 8 +- > > > > > > > .../net/wireless/mediatek/mt76/mt7996/mcu.c | 9 +- > > > > > > > .../wireless/mediatek/mt76/mt7996/mt7996.h | 28 +- > > > > > > > 9 files changed, 807 insertions(+), 784 deletions(- > > > > > > ) create > > > > > > > mode 100644 > > > > > > > drivers/net/wireless/mediatek/mt76/mt76_connac3_mac.c > > > > > > > > > > > > > > diff --git a/drivers/net/wireless/mediatek/mt76/Makefile > > > > > > > b/drivers/net/wireless/mediatek/mt76/Makefile > > > > > > > index 84c99b7e57f9..d8e8079c8b54 100644 > > > > > > > --- a/drivers/net/wireless/mediatek/mt76/Makefile > > > > > > > +++ b/drivers/net/wireless/mediatek/mt76/Makefile > > > > > > > @@ -27,7 +27,7 @@ mt76x02-lib-y := mt76x02_util.o > > > > > > mt76x02_mac.o > > > > > > > mt76x02_mcu.o \ > > > > > > > > > > > > > > mt76x02-usb-y := mt76x02_usb_mcu.o mt76x02_usb_core.o > > > > > > > > > > > > > > -mt76-connac-lib-y := mt76_connac_mcu.o mt76_connac_mac.o > > > > > > > +mt76-connac-lib-y := mt76_connac_mcu.o mt76_connac_mac.o > > > > > > > mt76_connac3_mac.o > > > > > > > > > > > > > > obj-$(CONFIG_MT76x0_COMMON) += mt76x0/ > > > > > > > obj-$(CONFIG_MT76x2_COMMON) += mt76x2/ diff --git > > > > > > > a/drivers/net/wireless/mediatek/mt76/mt76_connac.h > > > > > > > b/drivers/net/wireless/mediatek/mt76/mt76_connac.h > > > > > > > index 68bdeada1421..20111678537b 100644 > > > > > > > --- a/drivers/net/wireless/mediatek/mt76/mt76_connac.h > > > > > > > +++ b/drivers/net/wireless/mediatek/mt76/mt76_connac.h > > > > > > > @@ -415,4 +415,23 @@ void mt76_connac2_txwi_free(struct > > > > > > mt76_dev > > > > > > > *dev, struct mt76_txwi_cache *t, > > > > > > > struct list_head *free_list);
