      ath5k: correct padding in tx descriptors · 281c56dd
      Bruno Randolf authored
      
      
      when setting up the tx descriptors for the hardware we must account for any
      padding between the header and the data we might have added previously. frame
      len is the length of the frame in the air (including FCS but no padding) and
      buffer len is the length of the buffer (including padding, but without FCS).
      
      changing the way ah_setup_tx_desc is called: now excluding the FCS, since it's
      easier to add that in the function where we need it.
      
      before this fix we sent trailing zero bytes after the packet (because frame len
      included the padding) which was not a big problem without WEP, but with WEP
      this resultes in a wrong WEP checksum and the packet is discarded - which is
      how i noticed at all ;)
      
      an easy way to run into header padding problems, btw, is to connect to a QoS
      (WME) enabled access point (eg. madwifi) - QoS data frames are 2 byte longer
      and will require padding.
      
      this patch applies on top of luis latest patch series from 04.02.2008.
