4 Subject: [PATCH 2/3] net: vmxnet: initialise local tx descriptor
6 In Vmxnet3 device emulator while processing transmit(tx) queue,
7 when it reaches end of packet, it calls vmxnet3_complete_packet.
8 In that local 'txcq_descr' object is not initialised, which could
9 leak host memory bytes a guest.
