From d781ccbdd15d422a65ed1794aa58a182ae870a54 Mon Sep 17 00:00:00 2001 From: Qi Zhang Date: Mon, 25 Mar 2019 13:44:25 +0800 Subject: [PATCH] net/ice/base: add functions to get allocated resources 1. ice_aq_get_res_alloc - get allocated resources. 2. ice_aq_get_res_descs - get allocated resource descriptors. These APIs may help to PMD to enable some debug utilities to dump the resource allocation status.
