      net: ipa: rename endpoint->trans_tre_max · 317595d2
      Alex Elder authored
      The trans_tre_max field of the IPA endpoint structure is only used
      to limit the number of fragments allowed for an SKB being prepared
      for transmission.  Recognizing that, rename the field skb_frag_max,
      and reduce its value by 1.

      net: ipa: rename channel->tlv_count · 88e03057
      Alex Elder authored
      Each GSI channel has a TLV FIFO of a certain size, specified in the
      configuration data for an AP channel.  That size dictates the
      maximum number of TREs that are allowed in a single transaction.
      
      The only way that value is used after initialization is as a limit
      on the number of TREs in a transaction; calling it "tlv_count"
      isn't helpful, and in fact gsi_channel_trans_tre_max() exists to
      sort of abstract it.
      
      Instead, rename the channel->tlv_count field trans_tre_max, and get
      rid of the helper function.  Update a couple of comments as well.

      net: ipa: verify command channel TLV count · 92f78f81
      Alex Elder authored
      In commit 8797972a ("net: ipa: remove command info pool"), the
      maximum number of IPA commands that would be sent in a single
      transaction was defined.  That number can't exceed the size of the
      TLV FIFO on the command channel, and we can check that at runtime.
      
      To add this check, pass a new flag to gsi_channel_data_valid() to
      indicate the channel being checked is being used for IPA commands.
      Knowing that we can also verify the channel direction is correct.
      
      Use a new local variable that refers to the command-specific portion
      of the data being checked.
