[dpdk-dev] [PATCH v1 2/2] net/vmxnet3: Provided API to reset vmxnet device

[Dheemanth Mallikarjun <dheemanthm@vmware.com>]

The vmxnet3 driver didn't have the dev_reset function
pointer set. Hence, provided the necessary function
pointer so that DPDK developers can use the rte_eth_dev_reset
API to reset the vmxnet3 device data.
