      iwlwifi: mvm: don't override the rate with the AMSDU len · 5c08b0f5
      Emmanuel Grumbach authored
      The TSO code creates A-MSDUs from a single large send. Each
      A-MSDU is an skb and skb->len doesn't include the number of
      bytes which need to be added for the headers being added
      (subframe header, TCP header, IP header, SNAP, padding).
      
      To be able to set the right value in the Tx command, we
      put the number of bytes added by those headers in
      driver_data in iwl_mvm_tx_tso and use this value in
      iwl_mvm_set_tx_cmd.
      
      The problem by setting this value in driver_data is that
      it overrides the ieee80211_tx_info. The bug manifested
      itself when we send P2P related frames in CCK since the
      rate in ieee80211_tx_info is zero-ed. This of course is
      a violation of the P2P specification.
      
      To fix this, copy the original ieee80211_tx_info to the
      stack and pass it to the functions which need it.
      Assign the number of bytes added by the headers to the
      driver_data inside the skb itself.
      
      Fixes: a6d5e32f ("iwlwifi: mvm: send large SKBs to the transport")
