====================
net: macb: DMA race condition fixes

Here are a couple of race condition fixes for the macb driver. The first
two are for issues observed at runtime on real HW.

v2:
- added received Tested-bys and Acked-bys to the first two patches
- in patch 3/3, moved the timestamp protection barrier closer to the
  timestamp reads
- in patch 3/3, removed unnecessary move of the addr assignment in
  gem_rx() to keep the patch minimal for maximum clarity
- in patch 3/3, clarified commit message and comments

The 3/3 is the same one I improperly sent last week as a standalone
patch.
