vmxnet3: support higher link speeds from vmxnet3 v9

Until now, vmxnet3 was default reporting 10Gbps as link speed.
Vmxnet3 v9 adds support for user to configure higher link speeds.
User can configure the link speed via VMs advanced parameters options
in VCenter. This speed is reported in gbps by hypervisor.

This patch adds support for vmxnet3 to report higher link speeds and
converts it to mbps as expected by Linux stack.
