ethtool: fix missing NLM_F_MULTI flag when dumping
When dumping the ethtool information from all the interfaces, the netlink reply should contain the NLM_F_MULTI flag. This flag allows userspace tools to identify that multiple messages are expected. Link: https://bugzilla.redhat.com/1953847 Fixes: 365f9ae4ee36 ("ethtool: fix genlmsg_put() failure handling in ethnl_default_dumpit()") Signed-off-by: Fernando Fernandez Mancera <ffmancera@riseup.net> Signed-off-by: David S. Miller <davem@davemloft.net>
