Comment # 1 on bug 1771 from Stephen Hemminger 
That is an old release. GCC 15 sup=
port was addressed in commit in main
which was not backported. Since version 23.11 pre-dates the release of that=
 OS
release, it is unreasonable to expect backport.

Use a later DPDK release please.

    ethdev: convert string initialization

    gcc 15 experimental [1], with -Wextra flag, gives warning in variable
    initialization as string [2].

    The warning has a point when initialized variable is intended to use as
    string, since assignment is missing the required null terminator for
    this case. But warning is useless for our usecase.

    In this patch only updated a few instance to show the issue, there are
    many instances to fix, if we prefer to go this way.
    Other option is to disable warning but it can be useful for actual
    string usecases, so I prefer to keep it.

    Converted string initialization to array initialization.
