s2io does. e1000 does it with skb frags.
If your hardware allows header split and driver can put headers into
skb->data and real data into frag_list, that allows to create various
interesting things like receiving zero-copy support and netchannels
support. It is work in progress, not official direction currently,
but this definitely will help your driver to support future high
performance extensions.
