Also, it looks like round-robin mode has been removed from tab completion, but it is still listed in the question-mark output and it's still accepted:
[Global] DallasticXL-s01-01> set bonding group 2 mode [Tab]
active-backup xor 8023AD
[Global] DallasticXL-s01-01> set bonding group 2 mode ?
Set the bonding policy for the bond group.
The types of policy, as indicated in parentheses, are high-availability (HA) and load-sharing (LS).
The following modes/policies are supported:
round-robin - (HA+LS) use all interfaces sequentially.
active-backup - (HA) use one interface at a time.
xor - (HA+LS) use interfaces based on a hash function.
8023AD - (LS) dynamic bonding via IEEE 802.3ad.
[Global] DallasticXL-s01-01> set bonding group 2 mode
Is round-robin being dropped, or should it appear in tab completion?
