      i40e: remove unnecessary __packed · 9588397d
      Tushar Dave 提交于
      'struct i40e_dma_mem' defined with 'packed' directive causing kernel
      unaligned errors on sparc.
      
      e.g.
      i40e: Intel(R) Ethernet Connection XL710 Network Driver - version
      1.6.16-k

      This can be fixed with get_unaligned/put_unaligned(). However no
      reference in driver shows that 'struct i40e_dma_mem' directly shoved
      into NIC hardware. But instead fields of the struct are being read and
      used for hardware. Therefore, __packed is unnecessary for 'struct
      i40e_dma_mem'.
      
      In addition, although 'struct i40e_virt_mem' doesn't cause any
      unaligned access, keeping it packed is unnecessary as well because
      of aforementioned reason.
      
      This change make 'struct i40e_dma_mem' and 'struct i40e_virt_mem'
      unpacked.
