vmxnet3: Use single tx queue when CONFIG_PCI_MSI not defined
Resending this patch with few changes. Avoid multiple queues when MSI or MSI-X not available Limit number of Tx queues to 1 if MSI/MSI-X support is not configured in the kernel. This will make number of tx and rx queues equal when MSI/X is not configured thus providing better performance.
