From 999284fcc3043cf1c1d15e825ed7d77cf491f2fe Mon Sep 17 00:00:00 2001 From: Takayuki Usui Date: Wed, 3 Dec 2014 10:37:26 +0900 Subject: [PATCH] kni: create interface in current network namespace With this patch, KNI interface (e.g. vEth0) is created in the network namespace where the DPDK application is running. Otherwise, all interfaces are created in the default namespace in the host. put_net() is required, since get_net_ns_by_pid() increments the reference counter of the network namespace with get_net().
