Per Andreas' review comment, this one has been abandoned because the new one #30389 is created with the same Change-Id:I6eeefbf74017aaeeb8998accd6da04d8de75606c to #30365 for b2_10.

It looks like this is caused by the test checking for version 2.8.52 on the server before setting brw_size to be larger. With 2.7.x the 16MB RPC patch is available, but the default brw_size is 1MB.

The test needs to be updated to check for version 2.7.17 or later to set brw_size=16 and enable the 8MB and 16MB RPC tests. The suffix="M" change is NOT available in 2.7.x and should be left under the version > 2.9.52 check.

This should be fixed in b2_10 and master.
