For hardware NICs, this operation is usually performed by calling netmap_reset from the driver patch. You can look at intel drivers, for example, or vmxnet3.

Hi, sorry for the late reply. We are more than willing to merge this, but vanilla patches are auto-generated from a different repository which is a clone of vanilla linux. You find a copy of the repo here: https://github.com/giuseppelettieri/linux-pspat. There is a netmap-$v branch for each version of linux. You should remove the vanilla--octeon--* file from this pull request and create a pull request for the other repo, containing only the necessary changes for the driver. You can target any one of the netmap-$v branches. I will then try to forward/backword port the commit as much as possible and then auto-generate the patch for the netmap repository.
