[PATCH 0/5][next] net: Avoid thousands of -Wflex-array-member-not-at-end warnings

["Gustavo A. R. Silva" <gustavoars@kernel.org>]

This series aims to resolve thousands of -Wflex-array-member-not-at-end
warnings by introducing `struct sockaddr_legacy`. The intention is to use
it to replace the type of several struct members in the middle of composite
structures, currently of type `struct sockaddr`.

These middle struct members are currently causing thousands of warnings
because `struct sockaddr` contains a flexible-array member, introduced
by commit b5f0de6df6dce ("net: dev: Convert sa_data to flexible array in
struct sockaddR").

The new `struct sockaddr_legacy` doesn't include a flexible-array
member, making it suitable for use as the type of middle members
in composite structs that don't really require the flexible-array
member in `struct sockaddr`, thus avoiding -Wflex-array-member-not-at-end
warnings.
