From: Pallavi Kadam Date: Mon, 27 Sep 2021 18:43:22 +0000 (-0700) Subject: bus/pci: fix unknown NUMA node value on Windows X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=3c6e581025109926c166bbd2f7ea678f07c3bbce;p=dpdk.git bus/pci: fix unknown NUMA node value on Windows Based on the rte_eth_dev_socket_id() documentation, set the default numa_node to -1. When the API is unsuccessful, set numa_node to 0. This change more correctly resembles the Linux code.
