I'm trying to emulate Raspberry Pi via QEMU and the following works for me:
qemu-system-arm
-append "root=/dev/sda2 panic=1 rootfstype=ext4 rw"
-boot c
-cpu arm1176
-drive "file=2019-04-08-raspbian-stretch-lite.img,if=scsi,cache=none,discard=ignore,format=raw"
-kernel ./kernel-qemu-4.4.34-jessie
-m 256M
-machine type=versatilepb,accel=tcg
-name packer-qemu
-no-reboot
-vnc 127.0.0.1:4
-net nic
-net user,id=user.0,hostfwd=tcp::5555-:22
and I'm able to both VNC in via 5904 and SSH in via 5555 (after starting SSHd via VNC). In other words network seems to be set up correctly.
As I discovered -net option has been deprecated in favour of -device & -netdev, so I'd like to translate the above two last flags into "new QEMU".
It appears that the new -device flag forces me to pick a driver, which isn't the case with -net. I like explicitness, but how do I know what is the default/implicit driver?
Port forwarding in the following example doesn't seem to work anymore (I can't SSH in; connection times out):
qemu-system-arm
-append "root=/dev/sda2 panic=1 rootfstype=ext4 rw"
-boot c
-cpu arm1176
-drive "file=2019-04-08-raspbian-stretch-lite.img,if=scsi,cache=none,discard=ignore,format=raw"
-kernel ./kernel-qemu-4.4.34-jessie
-m 256M
-machine type=versatilepb,accel=tcg
-name packer-qemu
-no-reboot
-vnc 127.0.0.1:4
-device e1000,netdev=user.0
-netdev user,id=user.0,hostfwd=tcp::5555-:22
Am I just using wrong driver?

I managed to make it work with-nic user,id=user.0,hostfwd=tcp::5555-:22(which seems to be a new flag too) but I'm still very confused about differences between all these flags and I'm still curious whether they are replaceable with each other.

qemu.org/2018/05/31/nic-parameter provides some background with some hints that these flags may not actually be equivalent. Should I turn this into an answer?

you should, if it works for you. as a completion, you can check the default network device withinfo networkin the qemu monitor (for your machine (versatilepb) it's probably smc91c111.
