AIUI that was just certain flavors of Broadwell and possibly all (or maybe just all-released-at-the-time) Haswell chips, so later Broadwell steppings had a working TSX implementation.
(As an example, my Xeon D-1540, a Broadwell-family chip, advertises the TSX bits in CPU feature flags, so it's not errata'd off there.)
