--- Comment #1 from Stephen Hemminger (stephen@networkplumber.org) ---
That is an old release. GCC 15 support 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.
