5597b8a9e2 drivers/virtio-net: Add support to offload small IOBs
TCP receive tested with different IOB_BUFSIZE:
|             | 256B vs 1534B | 512B vs 1534B | 768B vs 1534B |
| :---------: | :-----------: | :-----------: | :-----------: |
|     Non-SMP |     ~85%      |     ~93%      |     ~96%      |
|  armv8a-SMP |     ~66%      |     ~84%      |     ~92%      |
| rv32/64-SMP |     ~52%      |     ~72%      |     ~83%      |

It seems we still get performance penalty on smaller IOBs, and may be
affected more under SMP mode. It may be caused by critical sections in
IOB operations.

2fa68fbddd drivers/virtio-net: Support different LL_GUARDSIZE
Previously, the CONFIG_NET_LL_GUARDSIZE is fixed to 32 (64-Bit) or
28 (32-Bit), it's a little bit tricky.
Now add support to any value greater than minimal size.

9aa57b6c53 virtio: add virtio framework in NuttX
1. virtio devics/drivers match and probe/remote mechanism;
2. virtio mmio transport layer based on OpenAmp (Compatible with both
   virtio mmio version 1 and 2);
3. virtio-serial driver based on new virtio framework;
4. virtio-rng driver based on new virtio framework;
5. virtio-net driver based on new virtio framework
   (IOB Offload implementation);
6. virtio-blk driver based on new virtio framework;
7. Remove the old virtio mmio framework, the old framework only
   support mmio transport layer, and the new framwork support
   more transport layer and this commit has implemented all the
   old virtio drivers;
8. Refresh the the qemu-arm64 and qemu-riscv virtio related
   configs, and update its README.txt;

New virtio-net driver has better performance
Compared with previous virtio-mmio-net:
