Problems fixed in this release
The following problems were fixed in this release:
DescriptionSR number
Outbound Discards are seen on Guest LAN InterfaceQXCR1001318295
For a traffic from AVIO Guest, unexpected Outbound Discards are seen on the guest LAN interface
and on the VSP LAN interface that is used by guest LAN interface.
System panic from wait_for_lock: Already owns lock: iocxgbe_mq_lockQXCR1001318145
When the speed setting is changed from VCM for a port in an APA group configuration, a system
panic can be seen.
LRO may truncate/Enlarge TCP frames causing TCP performance degradationQXCR1001340515
LRO may truncate/enlarge TCP frames causing TCP performance degradation. The software LRO
algorithm may try to coalesce an additional packet which does not belong to the same TCP segment.
This can causes packet discards. This is a rare scenario involving a specific traffic pattern having TCP
timestamps and sacks options.
