Hi all, 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.
