Add warning to be printed if 'use_tcp_bonding' option is used
notifying the user that the feature is being deprecated.
It is suggested to use MR configuration with dynamic discovery
instead.
Multi-Rail feature doesn't need to be explicitly enabled.
To use MR instead of tcp bonding, group the interfaces
on the same network using the lnetctl utility:
lnetctl net add --net tcp --if eth2,eth3
or via the modprobe configuration file (/etc/modprobe.d/lnet.conf
or /etc/modprobe.d/lustre.conf):
options lnet networks="tcp(eth2,eth3)"
and make sure dynamic discovery is enabled:
lnetctl set discovery 1
MR will aggregate the throughput of all configured and available
networks/interfaces shared between peer nodes.
