From f0684c51ec82bd24ab83889d94ad45da9965ad83 Mon Sep 17 00:00:00 2001 From: Helin Zhang Date: Thu, 30 Apr 2015 23:03:14 +0800 Subject: [PATCH] i40e/base: rework virtual address retrieval for lan queue To simplify the usage of invoking 'i40e_hmc_get_object_va', input parameters of it were reworked. In addition, minor code style fixes were added as well.
