Subject: [PATCH net-next 05/21] tipc: Remove code to emulate loss of broadcast messages

From: Allan Stephens <allan.stephens@...driver.com>

Eliminates optional code used to test TIPC's ability to recover
from lost broadcast messages. This code duplicates functionality
already provided by the network stack's QoS option "network emulator".
