why no net card? can you help me?
Because you didn't specify any emulated NIC in qemu command line.
Here's a link maybe you can refer:
https://www.suse.com/documentation/sles11/book_kvm/data/cha_qemu_running_net...
See the "Defining a Network Interface Card" section. The commonly used model with U-Boot should be e1000 or rtl8139 (rtl8139 is not converted to driver model though)
