  Log:
  A couple bug fixes that I've had internally at Intel. First is a long
  time workaround for problems with 82571 adapters and LAAs, one port
  getting reset can cause the other to have its RAR[0] also reset,
  thus overwriting an LAA. This fix works around it by also keeping
  the address in the last array member.
  
  The other bug is specific to the new 575 adapter, its transmit code
  logic in handling hwassists was too crude, it broken when doing
  bridges. I am much happier with the new logic,we may want to change
  the legacy path at some point to something similar.
