Hi Rashmin
I have tried the memset change but still I am facing the problem which
I pointed out earlier. After restart, packets are not being received
in vmxnet3_recv_pkts().
I have also observed PANIC in vmxnet3_tq_tx_complete() after couple of
stop and start operations.

Update max RX packet length since virtio PMD has the capability of receiving
and transmitting jumbo frame.
This following patch provides the above capability:

This patch implements the KNI memzone pool in order to prevent
memzone exhaustion when allocating/deallocating KNI interfaces.
It adds a new API call, rte_kni_init(max_kni_ifaces) that shall
be called before any call to rte_kni_alloc() if KNI is used.

Since vlan_tci is initialized to zero by rte_pktmbuf layer,
the driver shouldn't be messing with it.
Hi Helin,
Should we define packet classification types separately and do not reuse bit
shifts for RSS register as pctypes?
Packet classification is a global index table which used by RSS Hash Enable
registers, not vice versa.
For example, there is no Packet classification named
