All PSC based npumgr's assert with:
Assertion failure at npu/npumgr/npumgr_bspl.c:775
  Function: bspl_get_exact_subtrie_match()
  Expression: level

Conditions:
During customer network updates some IPv6 ECMP routes are being learned that are mis-handled in the npumgr and are causing the npumgr to assert.  Since they all assert the system becomes unstable.
