Subject: [PATCH net-next 0/2] inet: ping: remove extra skb_clone()/consume_skb()

First patch in the series moves ICMP_EXT_ECHOREPLY handling in icmp_rcv()
to prepare the second patch.

The second patch removes one skb_clone()/consume_skb() pair
when processing ICMP_EXT_REPLY packets. Some people
use hundreds of "ping -fq ..." to stress hosts :)

Eric Dumazet (2):
  ipv4: icmp: do not process ICMP_EXT_ECHOREPLY for broadcast/multicast
    addresses
  inet: ping: avoid skb_clone() dance in ping_rcv()
