[Qemu-devel] [PATCH v3] net: netmap: implement virtio-net header probe |

Current implementation for netmap backend does not really probe the netmap
kernel module to know whether virtio-net header is supported for a specific
netmap port. This is only correct for VALE ports, but it is not correct for
hardware ports, pipes, etc.
This patch properly implements the missing probe mechanism, fixing the
implementation of the involved hooks (has_vnet_hdr, has_vnet_hdr_len, has_ufo,
...).
CHANGELOG:
- renamed netmap_do_set_vnet_hdr_len to netmap_fd_set_vnet_hdr_len
- abort() when failing to restore previous vnet-hdr length
- moved update to s->vnet_hdr_len to netmap_set_vnet_hdr_len
