Subject: [PATCH] net: mediatek: wed: Introduce MT7992 WED support to MT7988
|
|
SoC
|
|
|
|
Introduce the second WDMA RX ring in WED driver for MT7988 SoC since the
|
|
Mediatek MT7992 WiFi chipset supports two separated WDMA rings.
|
|
Add missing MT7988 configurations to properly support WED for MT7992 in
|
|
MT76 driver.
