Segments being processed for large receive offload (LRO) (the action the system performs to aggregate multiple incoming packets within a buffer before passing them up) might be erroneously VLAN-tagged when LRO is enabled.
Egress traffic might sometimes be tagged.
-- TCP LRO enabled. -- Egress VLAN untagged.
Disable TCP LRO. To enable or disable LRO functionality, you can use the following command syntax: tmsh modify sys db tm.tcplargereceiveoffload value <enable | disable>
The system now ensures that fragment packet flags are correctly set.
