Nicolas Dichtel 37355565ba ip6_tunnel: fix error code when tunnel exists ... After commit 2b0bb01b6e, the kernel returns -ENOBUFS when user tries to add an existing tunnel with ioctl API: $ ip -6 tunnel add ip6tnl1 mode ip6ip6 dev eth1 add tunnel "ip6tnl0" failed: No buffer space available It's confusing, the right error is EEXIST. This patch also change a bit the code returned: - ENOBUFS -> ENOMEM - ENOENT -> ENODEV Fixes: 2b0bb01b6e ("ip6_tunnel: Return an error when adding an existing tunnel.")
