[PATCHv3 net-next 0/7] pktgen IPsec support

[Fan Du <fan.du@windriver.com>]

Hi, Dave

Current pktgen IPsec supports only transport/ESP combinnation,
This patchset enables user to do almost any IPsec transformation,
both transport/tunnel mode, and AH/ESP/IPcomp type.

Below configuration has been tested, and using Wireshark could decrypt
out plain text in good formation without any checksum/auth errors:

Mode/TYPE   AH  ESP 
Transport   x   x   
Tunnel      x   x   

ChangeLog
v2:
  Rebase patchset against newest net-next.
  Patch1: Remove adding rebundant empty line spotted by Sergei.
  Patch2: Use only one dst pointing into itself to save space.

v3:
  Align with David's requirement, that for user depends on orignal
  a553e4a6317b2cfc7659542c10fe43184ffe53da ("IPSEC support") from
  Jamal, their testbed configuration will not need to be changed. 

  Adding Patch2/7, Patch3/7 for statistic counting, as well as fixing
  lock usage issue.
