Re: [net-next PATCH 07/10] virtio_net: Update driver to use ethtool_sprintf

From: Alexander Duyck <alexanderduyck@fb.com>

Update the code to replace instances of snprintf and a pointer update with
just calling ethtool_sprintf.

Also replace the char pointer with a u8 pointer to avoid having to recast
the pointer type.
