Repeated kernel panic related to vmxnet3 driver

Issue

• We have enabled kdump to capture the error after several kernel panics. Have upgraded vmware-tools to 9.0.0-2 and kernel to 2.6.32-431.el6.x86_64 but still experiencing the kernel panic.

• kernel BUG at drivers/net/vmxnet3/vmxnet3_drv.c:1187!

• The system panics randomly in the vmxnet3 driver at different code points.

• Kernel panics in vmxnet3 with vmxnet3_rq_rx_complete , vmxnet3_poll_rx_only and vmxnet3_tq_tx_complete

• VMWare VMs panic with backtrace similar to:

    [exception RIP: vmxnet3_rq_rx_complete+1885]
