Message-Id: <1548059825-78171-1-git-send-email-feng.tang@intel.com> Date: Mon, 21 Jan 2019 16:37:05 +0800 From: Feng Tang <feng.tang@...el.com> To: Jeff Kirsher <jeffrey.t.kirsher@...el.com>, "David S . Miller" <davem@...emloft.net>, intel-wired-lan@...ts.osuosl.org, netdev@...r.kernel.org Cc: Feng Tang <feng.tang@...el.com> Subject: [PATCH] igb: Make driver init async When optimizing boot time for a platform with igb module, we found the igb driver probe will take about 45 ms, make the probe asynchronous will save quite some time as the init runs in parallel with other asynchronous drivers. In theory, this could be applied to some other drivers like igc or e1000, but we don't have HW to verify that.
