This series adds a new full-MAC Wi-Fi driver `nxpwifi` to support NXP IW61x chip family. These chips are tri-radio single-chip solutions with Wi-Fi 6 (1x1, 2.4/5 GHz), Bluetooth 5.4, and IEEE 802.15.4. Communication with the external host is via SDIO interface. The driver is tested on i.MX8M Mini EVK in both STA and AP mode. This driver is not based on mac80211. It derives from mwifiex, but due to significant differences in firmware architecture, host command interface, and supported features, it was not feasible to extend mwifiex without risk of regressions. Thus, a new driver is introduced. Future NXP Wi-Fi chipsets will also be supported under `nxpwifi`. The driver passes checkpatch. WPA2/WPA3 personal/enterprise is currently handled in host via wpa_supplicant/hostapd. v4 adds support for TWT, monitor mode, WPA3 Enterprise Suite-B, and various fixes and improvements. See below for full changelog. Data sheet is available at: https://www.nxp.com/docs/en/data-sheet/IW612.pdf Change history: v4: - Added support for TWT (STA mode) - Added support for Monitor mode - Added support for WPA3 Enterprise Suite-B - Bug fix: In BGN/AN HT40 mode, throughput was 50% lower than expected - Bug fix: In STA 2.4G HE40 mode, throughput was 80% lower than expected - Use wiphy work instead of general workqueue for cfg80211 ops - Introduced RCU protection for ba, rx_reorder, and sta_lists - Used per-TID spinlock for tx_ba / rx_reorder lists to improve concurrency - Replaced mutex_lock with wiphy_lock - Reverted "use tasklet for Rx" (back to workqueue) - Refactored HE capability handling for better clarity and maintainability - Used standard kernel helpers for MAC address handling - Replaced proprietary nxpwifi_ieee80211 with standard ieee80211_mgmt structure - Used u32_get_bits() for VHT capability field access - Replaced LOW_PRIO_TID with TC_PRIO_BESTEFFORT for skb priority - Removed static WPA/RSN OUI table; now derived from cipher suite ID - Removed redundant helper functions: has_vendor_hdr() and has_ieee_hdr( v3: - Enable 802.11ax (Wi-Fi 6) for both AP and STA mode. - Extend driver verion string with hotfix number. - Remove Rx mlme work. - Remove all useless check of netif_carrier_ok(). - Merge decl.h to cfg.h. - Remove unnecessary check for wiphy parameters setting. - Synchronize following commits from Mwifiex: wifi: mwifiex: replace open-coded module_sdio_driver() wifi: mwifiex: Fix interface type change wifi: mwifiex: Do not return unused priv in mwifiex_get_priv_by_id() wifi: mwifiex: increase max_num_akm_suites wifi: mwifiex: duplicate static structs used in driver instances wifi: mwifiex: keep mwifiex_cfg80211_ops constant wifi: mwifiex: Fix uninitialized variable in mwifiex_cfg80211_authenticate() wifi: mwifiex: remove unnecessary checks for valid priv wifi: mwifiex: Fix memcpy() field-spanning write warning in mwifiex_cmd_802_11_scan_ext() wifi: mwifiex: Use IRQF_NO_AUTOEN flag in request_irq() v2: - Rename ioctl.h and sta_ioctl.c to cfg.h and sta_cfg.c. - Remove useless header file semaphore.h. - Use static variable for cookie. - Modify nxpwifi_register to use ERR_PTR, IS_ERR and PTR_ERR. - Use error number for error code. - Remove unnecessary private ie definitions. - Remove mutex async_mutex and related code. - Remove unnecessary work queue. - Add the support for PSK SHA256. - Use tasklet for Rx. - Remove unused functions. - Remove compile warning.
