As an aside I think the RDMA proposal has a lot of holes too.  For
example, there are in-kernel HTTP accelerators that do the complete
client header parse and initial packet response in the hw interrupt
handler.  There are no user buffers involved, and static response
data is DMA'd directly from the filesystem page cache.

   There is no DNS entry for ftpeng.cisco.com so I can't access the
   document.

Here is what I get:

? host -a ftpeng.cisco.com
Trying null domain
rcode = 0 (Success), ancount=1
