            Bug ID: 1774
           Summary: Build error: static assertion failed:
                    "GMAC_LARGE_PLAINTEXT_LENGTH should not be greater
                    than LARGE_MBUF_DATAPAYLOAD_SIZE"
           Product: DPDK
           Version: 25.07
          Hardware: x86
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: other
          Assignee: dev at dpdk.org

This commit
https://github.com/DPDK/dpdk/commit/6a9f3f6df9ef51e30ff5bf3eea00f27ffef87a16
enables RTE_PKTMBUF_HEADROOM to be tuned from the build process. However,
GMAC_LARGE_PLAINTEXT_LENGTH setting of 65344 fails a static assert if
RTE_PKTMBUF_HEADROOM is set to 192. Changing it to 65343 would pass the build.


meson setup -Dplatform=x86_64 -Dpkt_mbuf_headroom=192 -Dmax_lcores=128
-Dmax_ethports=64
-Denable_drivers=bus/auxiliary,bus/pci,common/mlx5,net/mlx5,net/tap
-Denable_driver_sdk=true -Dcpu_instruction_set=broadwell -Dprefix=/ build; cd
build &&
