net: use core MTU range checking in virt drivers
hyperv_net: - set min/max_mtu, per Haiyang, after rndis_filter_device_add virtio_net: - set min/max_mtu - remove virtnet_change_mtu vmxnet3: - set min/max_mtu xen-netback: - min_mtu = 0, max_mtu = 65517 xen-netfront: - min_mtu = 0, max_mtu = 65535 unisys/visor: - clean up defines a little to not clash with network core or add redundat definitions CC: netdev@vger.kernel.org CC: virtualization@lists.linux-foundation.org CC: "K.
