      rxrpc: Add re-sent Tx annotation · f07373ea
      David Howells 提交于
      Add a Tx-phase annotation for packet buffers to indicate that a buffer has
      already been retransmitted.  This will be used by future congestion
      management.  Re-retransmissions of a packet don't affect the congestion
      window managment in the same way as initial retransmissions.

      rxrpc: Don't store the rxrpc header in the Tx queue sk_buffs · 5a924b89
      David Howells 提交于
      Don't store the rxrpc protocol header in sk_buffs on the transmit queue,
      but rather generate it on the fly and pass it to kernel_sendmsg() as a
      separate iov.  This reduces the amount of storage required.
      
      Note that the security header is still stored in the sk_buff as it may get
      encrypted along with the data (and doesn't change with each transmission).
