      net: Increase default NET_SKB_PAD to 32. · d6301d3d
      David S. Miller authored
      Several devices need to insert some "pre headers" in front of the
      main packet data when they transmit a packet.
      
      Currently we allocate only 16 bytes of pad room and this ends up not
      being enough for some types of hardware (NIU, usb-net, s390 qeth,
      etc.)
      
      So increase this to 32.
      
      Note that drivers still need to check in their transmit routine
      whether enough headroom exists, and if not use skb_realloc_headroom().
      Tunneling, IPSEC, and other encapsulation methods can cause the
      padding area to be used up.
