<pre class="bz_comment_text">The DPDK main branch, on commit 7e06c0de1952d3109a5b0c4779d7e7d8059c9d78,
encounters a compilation error on Alpine Linux. This appears to be a new issue
caused by us upgrading our container image, which includes newer versions of
GCC and musl.
GCC version: (Alpine 13.2.1_git20231014) 13.2.1 20231014
musl-libc version: 1.2.4_git20230717-r4
Kernel: 5.4.0-167 generic
Output from GCC:
../drivers/bus/pci/linux/pci_vfio.c: In function 'pci_vfio_read_config':
../drivers/bus/pci/linux/pci_vfio.c:83:16: warning: implicit declaration of
