[PATCH 07/12] ipwireless: Do not return value from sending funcs

[David Sterba <dsterba@suse.cz>]

ipwireless: Do not return value from sending funcs

Do not return value from do_send_fragment and do_send_packet, it's not used.
The packet size checks are not useful too:

* zero length packet will never be sent, caller always passes packet_header
  size which is either 1 or 3
* MTU check is done in caller, no need to repeat
