Re: [PATCH 21/24] net, diet: Make packet tpacket/mmap/fanout/rings optional

Many DHCP clients need basic packet sockets, but they don't need
the fancy zero copy packet capture code, like tpacket, mmap, rings,
fanouts. This is quite substantial code, so it's worthwhile to
make it optional

Worth nearly 10k code.

Sorry, I'm not applying this either.

Small systems use packet generation and reception tools commonly, and
the only sane way to do so is with tpacket.
