Subject: [PATCH 08/16] app/testpmd: remove use of VLAs for Windows built code
Date: Wed, 17 Apr 2024 16:41:51 -0700 [thread overview]
Message-ID: <1713397319-26135-9-git-send-email-roretzla@linux.microsoft.com> (raw)
In-Reply-To: <1713397319-26135-1-git-send-email-roretzla@linux.microsoft.com>
MSVC does not support VLAs, replace VLAs with standard C arrays
or alloca(). alloca() is available for all toolchain/platform
combinations officially supported by DPDK.
