2023-05-25wifi: rtw89: use struct and le32_get_bits() to access RX descriptorPing-Ke Shih1-65/+0
RX descriptor is to provide basic and important information related to packets, such as packet size, security, MAC ID and so on. Change to use struct to access these fields, and not change logic at all.

2023-05-25wifi: rtw89: use struct and le32_get_bits() to access received PHY status IEsPing-Ke Shih1-18/+19
PHY status IEs generated by BB hardware is to provide more detail information related to received packets, such as RSSI and bandwidth. To avoid type casting, change buf type from u8* to void* as well. This patch doesn't change logic at all.

2023-05-25wifi: rtw89: use struct and le32_get_bits to access RX infoPing-Ke Shih1-28/+25
If received packet type is PPDU status, RX info provides information attached by MAC hardware, and mention how long BB information attached. This conversion patch doesn't change logic at all.

2022-12-14wifi: rtw89: consider ER SU as a TX capabilityPing-Ke Shih1-0/+2
ER (Extended Range) SU is to have a larger coverage. We set this as a RA capability, and then firmware can choose ER SU to transmit packets to reception at cell edge. For 8852C, it needs to fill this capability in TXWD, so update rtw89_build_txwd_info0_v1().

2022-11-22wifi: rtw89: read CFO from FD or preamble CFO field of phy status ie_type 1 ↵Eric Huang1-1/+3
accordingly Add macro to get FD(frequency domain) CFO field from ie_type 1, and correct the naming for preamble CFO field. Each IC could assign the CFO source to either FD CFO or preamble CFO in chip_info. Based on the suggestion from HW designer, rtw8852b and its derived versions will have better CFO tracking performance with FD CFO.

2022-04-06rtw89: read RX bandwidth from v1 type RX descriptorPing-Ke Shih1-0/+2

2022-04-06rtw89: support hardware generate security headerPing-Ke Shih1-0/+7
The newer chip will generate security header itself, so don't set IEEE80211_KEY_FLAG_GENERATE_IV in this kind of chip. But, it needs to fill key_index, PN and 802.11 header length to TX descriptor, and then hardware uses these to generate security header.

2021-12-08rtw89: fix incorrect channel info during scanPo Hao Huang1-40/+5
We used to fill in rx skbs' frequency field by mac80211's current channel value. In some cases, mac80211 switches channel before all rx packets have been processed. This results in incorrect bss info. We fix this by filling in frequency field with channel index obtained from hardware, then fix potential cck missing issue by skb's original hw rate. After all fix is done, convert hw rate back to the supported band rate index.

2021-10-13rtw89: add Realtek 802.11ax driverPing-Ke Shih1-0/+358
This driver named rtw89, which is the next generation of rtw88, supports Realtek 8852AE 802.11ax 2x2 chip whose new features are OFDMA, DBCC, Spatial reuse, TWT and BSS coloring; now some of them aren't implemented though. The chip architecture is entirely different from the chips supported by rtw88 like RTL8822CE 802.11ac chip. First of all, register address ranges are totally redefined, so it's impossible to reuse register definition. To communicate with firmware, new H2C/C2H format is proposed. In order to have better utilization, TX DMA flow is changed to two stages DMA. To provide rich RX status information, additional RX PPDU packets are added. Since there are so many differences mentioned above, we decide to propose a new driver.
