title: app:layout_scrollFlags="scroll|enterAlways" doesn't works with LinearLayout
body: <p>I have start working on Android material design support library, and as a newbie I have some confusions. And, need your help. :)</p>
  
  <p>1) Is it possible to use <code>layout_scrollFlags="scroll|enterAlways"</code> with LinearLayout?</p>
  
  <p>2) I want a LinearLayout just below the Toolbar. I achieved it using AppBarLayout, but I want to scroll the LinearLayout not Toolbar on scrolling the content below LinearLayout. Using <code>layout_scrollFlags="scroll|enterAlways"</code> on LinearLayout doesn't works.</p>
  
  <p>3) Can we use more than one AppBarLayout in CoordinatorLAyout and Toolbar in AppBarLayout?</p>
