 Description   

lnet_select_best_ni_on_local_net() contains logic for restricting
the NI selection to a net specified by lnet_peer::lp_disc_net_id. The
purpose of this is to ensure that LNet peers ping every interface on
a router at a regular interval as part of the LNet router health
feature. However, this logic is flawed in because lnet_msg_discovery()
is used to determine whether the message being sent is a discovery
message, but that function actually determines whether a give message
can trigger discovery
