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.
