The manpage is wrong. Only "del" works for the bridge. "delete" is
used to remove an address from the interface.

Probably a remainder of the brconfig/ifconfig merge.

I'll prepare a diff for the manpage if nobody beats me to it.

Uuhm?

This is an error in the manual page.

It came about due to the merge of brconfig(8) into ifconfig(8). When
brconfig was a seperate program either "delete <if>" or "del <if>"
would do the same thing.

However in ifconfig, "delete (noargs)" has a different meaning: delete
the first IP address on the interface. Hence, the first commandline
you entered is parsed as two commands: delete (with no argument), and
athn0. athn0 is not a good command...

In the new world order where they are merged, the right command to issue
regarding the bridge is simply "del <if>".
