Copy & paste is not allways the right way.
The previous patch for  netlink.c what not OK. The right patch is:

This is wrong BATADV_CMD_GET_TRANSTABLE_GLOBAL will not work with
get_tq_netlink_cb. And translate_mac_netlink will use
translate_mac_netlink_opts. Better create a dummy function which
only operates on "struct nlquery_opts" and returns NL_STOP on the
first call of this function.

Kind regards,

[B.A.T.M.A.N.] PATCH alfred

[Jean-Jacques Sarton]

I had problem with alfre which don't start. I'am using netfs.

Swen has proposed a patch which remove the batadv_interface_check()
function.
May way is an other regarding the transitional period where the
old an new feature are to be supported.

The formatting + spaces of this function seems to be quite wild.
Please clean that up.

It seems to be wrong to me that you try to query BATADV_CMD_GET_ORIGINATORS
twice but not the global translation table.
