-Wflex-array-member-not-at-end was introduced in GCC-14, and we are getting ready to enable it, globally.
Address the following warnings by changing the type of the middle struct members in various composite structs, which are currently causing trouble, from `struct sockaddr` to `struct sockaddr_legacy`. Note that the latter struct doesn't contain a flexible-array member. include/uapi/linux/wireless.h:751:33: warning: structure containing a flexible array member is not at the end of another structure [-Wflex-array-member-not-at-end] include/uapi/linux/wireless.h:776:25: warning: structure containing a flexible array member is not at the end of another structure [-Wflex-array-member-not-at-end] include/uapi/linux/wireless.h:833:25: warning: structure containing a flexible array member is not at the end of another structure [-Wflex-array-member-not-at-end] include/uapi/linux/wireless.h:857:25: warning: structure containing a flexible array member is not at the end of another structure [-Wflex-array-member-not-at-end] include/uapi/linux/wireless.h:864:25: warning: structure containing a flexible array member is not at the end of another structure [-Wflex-array-member-not-at-end] No binary differences are present after these changes.
