+Subject: [PATCH] fix(esp_hosted_ng): Fix build for kernel 7.1
+
+With commit:
+https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=033fe322f5852d5144a85978e880e01b1787fd0d
+many functions esp_cfg80211_*() have argument struct netdevice * subsituted
+with struct wireless_dev *. So let's add separate function headers and
+retrieve struct netdev * from struct wireless_dev * if Linux version >= 7.1.
+
+Upstream: https://github.com/espressif/esp-hosted/pull/736
