Revert "net: rtnetlink: Enslave device before bringing it up"
This reverts commit a4abfa627c3865c37e036bccb681619a50d3d93c. The patch broke: > ip link set dummy0 up > ip link set dummy0 master bond0 down This last command is useful to be able to enslave an interface with only one netlink message. After discussion, there is no good reason to support: > ip link set dummy0 down > ip link set dummy0 master bond0 up because the bond interface already set the slave up when it is up.
