error message 已經指出 "wireless_send_event" undefined
這是位於 net/wireless/wext-core.c 裡面
需要打開 menuconfig CONFIG_WEXT_CORE

Hi @didadidadi5 , 之前在測試中發現, 部分WiFi source, 在backports中的5.15 source沒辦法被編譯到. 像下列的wext-core.c, 只有下面的Linux 5.10部分會被編譯到.
$BUILD_DIR/$LINUX_DIR/backports-5.15.58-1/net/wireless/wext-core.c
$BUILD_DIR/$LINUX_DIR/linux-github_com_OpenNuvoton_MA35D1_linux_5_10_y_git-053068f87dfae465ecbeeb006089279bdccad154/net/wireless/wext-core.c

針對這個issue, 解決方式是缺少的部分要從Linux 5.10來選. 請在make linux-menuconfig下, 打開下列wireless extension相關選項.
-- Networking support ---> [] Wireless ---> [] Wireless extensions
-- Networking support ---> [] Wireless ---> [] WEXT_SPY
-- Networking support ---> [] Wireless ---> [*] WEXT_PRIV

關於這部分的update, 請參考 3690050, 我看其他platform例如 i.MX, 也是這樣解決的.
