You can delete them with
Code:
ip link delete dev teq10
and so on, but if they appear after a reboot, they will again appear after a reboot.
These devices are created by some software that you are running on your system. A quick search for
erspan0 tells me that this has something to do with
viewing traffic on a switch port, very specialized network technology. I would assume that your computer runs a switch port analysis application, and that the removal of these NICs would be detrimental to it.
What distro are you running, and what network management software (apart from systemd-networkd) is installed?
