I'm in the process of upgrading my web/database/nfs/jack-of-all-trades box
from 6.2 to RELENG_7.  I figured now would be a good time to clean up my
kernel config files.  I have the following in my old kernel config:

# Statically Link in accept filters
options       ACCEPT_FILTER_DATA
options       ACCEPT_FILTER_HTTP

# Zero copy sockets support.  This enables "zero copy" for sending and
# receiving data via a socket.  The send side works for any type of NIC,
# the receive side only works for NICs that support MTUs greater than the
# page size of your architecture and that support header splitting.  See
# zero_copy(9) for more details.
options       ZERO_COPY_SOCKETS

Are these options still working/recommended?  With all the changes to
networking over the years (this box was originally set up during the 4.x
days and has been upgraded many times) I have no idea if these are still
good things to have.

Thanks!
-Jon
