DPDK compiler warning when building on gcc 15

[richqubit]

When compiling f-stack's dpdk on Fedora 42 (using gcc 15.1.1), I get many similar warnings to this. These warnings were not present when compiling with gcc 14.

../lib/ethdev/rte_flow.h:2045:27: warning: initializer-string for array of ‘unsigned char’ truncates NUL terminator but destination lacks ‘nonstring’ attribute (4 chars into 3 available) [-Wunterminated-string-initialization]
 2045 |                 .dst_qp = "\xff\xff\xff",
      |                           ^~~~~~~~~~~~~~

This was fixed in DPDK commit DPDK/dpdk@e0d947a

[jfb8856606]

This has been fixed in the latest dev branch. The DPDK code in F-Stack now uses byte array initialization instead of string literals:

// Before (triggered GCC 15 warning):
.dst_qp = "\xff\xff\xff",

// After (fixed):
.dst_qp = { 0xff, 0xff, 0xff },

The dev branch also includes additional GCC 15 build fixes:

• 134961a8e - Fix build with GCC 15+ and DPDK 25.11+ (filters C23 #embed macros, checks rte_eth_link_get_nowait() return value)
• 6a8a0f60a - Fix build error with gcc-15.2.0 (adds missing -lz linker flag)

Please try the latest dev branch and let us know if you still see warnings.
