From 99610782edaaa88f6c442ff11662780aa161be85 Mon Sep 17 00:00:00 2001 From: Jia Yu Date: Fri, 7 Nov 2014 09:31:50 -0800 Subject: [PATCH] ethdev: update link status after start Since LSR interrupt is disabled by pmd drivers, link status in rte_eth_device is always down. Bond slave_configure() enables LSR interrupt on devices to get notification if link status changes. However, the LSC interrupt at device start time is still lost. In this fix, call link_update to read link status from hardware register at device start time.
