The ifc_stats do not correctly reflect the number of incoming octets/packets. There is a discrepancy between octets/packets in/out in the ifc_stats table, which tracks per-VLAN stats.


ifc_stats are incorrect for incoming octets and packets.


LRO is enabled and used for incoming packets.


Disable LRO using the following command: tmsh modify sys db tm.tcplargereceiveoffload value disable After modifying that variable, you must restart tmm for it to take effect (traffic disrupted while tmm restarts): bigstart restart tmm
