From b53bb527d88ae963bdf9bd71f222cf459fc59d2b Mon Sep 17 00:00:00 2001 From: Ioana Ciornei Date: Tue, 14 Jul 2020 16:34:28 +0300 Subject: [PATCH] staging: dpaa2-ethsw: use netif_running when checking for port up There are some cases where the switch interface needs to be disabled so that changes in the configuration can be made. In such cases, we should check for a running interface (bit __LINK_STATE_START of the netdev) instead of netif_carrier_ok(). This is because on open() we enable the switch interface even though the link up has not come out yet.
