+One-line Summary: remove dependence on nlev for some namelist defaults
+Github PR URL:
+
+Purpose of changes (include the issue number and title text for each relevant GitHub issue):
+
+Resolve #819 - dependance of some namelist default on the number of
+               vertical levels (lev)?
+- There are just two variables other than ncdata that have an nlev
+  attribute.  Those entries can be removed because there are no compsets
+  that use them.

+
+bld/namelist_files/namelist_defaults_cam.xml
+. remove entry for effgw_oro w/ nlev=60
+. remove entry effgw_beres_dp w/ nlev=110
+
+If there were any failures reported from running test_driver.sh on any test
+platform, and checkin with these failures has been OK'd by the gatekeeper,
+then copy the lines from the td.*.status files for the failed tests to the
+appropriate machine below.  All failed tests must be justified.
