From 2e14846d15addd349a909176473e936f0cf79075 Mon Sep 17 00:00:00 2001 From: Ziye Yang Date: Wed, 17 Feb 2016 09:54:33 +0800 Subject: [PATCH] doc: announce ABI change for PCI class The purpose of this patch is used to add a new field "class" in rte_pci_id structure. The new class field includes class_id, subcalss_id, programming interface of a pci device. With this field, we can identify pci device by its class info, which can be more flexible instead of probing the device by vendor_id OR device_id OR subvendor_id OR subdevice_id. For example, we can probe all nvme devices by class field, which can be quite convenient.
