Patch for 3.2.x, 3.4.x IP identifier regression
With commits 73f156a6e8c1 ("inetpeer: get rid of ip_id_count") and
04ca6973f7c1 ("ip: make IP identifiers less predictable"), IP
identifiers are generated from a counter chosen from an array of
counters indexed by the hash of the outgoing packet header's source
address, destination address, and protocol number. Thus, in
__ip_make_skb(), we must now call ip_select_ident() only after setting
these fields in the IP header to prevent IP identifiers from being
generated from bogus counters.
IP id sequence before fix: 18174, 5789, 5953, 59420, 59637, ...
After fix: 5967, 6185, 6374, 6600, 6795, 6892, 7051, 7288, ...
