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

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 &&
