Isn"t this the TcRedundancy parameter?
# TC redundancy
# Specifies how much neighbor info should
# be sent in TC messages
# Possible values are:
# 0 - only send MPR selectors
# 1 - send MPR selectors and MPRs
# 2 - send all neighbors
# defaults to 2
# TcRedundancy  2

I thought the discussion is on MPR coverage.
# MPR coverage
# Specifies how many MPRs a node should
# try select to reach every 2 hop neighbor
# Can be set to any integer >0
# MPR selection is broken at the moment, just keep 7
# MprCoverage   7

Now I wonder what is broken.

I test with dense 30 node network at the moment.
I didn't see this problem.
I did not check it in detail either.
