Bug description:
  ---Problem Description---
  FC Adapter goes offline and produces the call traces while booting into OS, on assigning the LUNs to it.
   
  ---uname output---
  Linux ltciofvtr-firestone1 4.9.0-12-generic #13-Ubuntu SMP Tue Jan 10 12:52:39 UTC 2017 ppc64le ppc64le ppc64le GNU/Linux
   
  FC Redfish Adapter(32 GB) is going offline on assigning the Luns to it. Adapter shows online till pettitboot and even Luns are also vissible in pettitboot.
  once selecting the OS from pettitboot and booting into it, it produces call traces and also few lpfc errors. attached the comple console logs FYR.
  The FC switch to which the Redfish adapter is connected is a 16 GB switch and the adapter is of 32 GB. According to me this parameter should not have any concern as the adapter has to support backward compatibility. 

  ---Steps to Reproduce---
  1. install the adapter in a server. and connect it to FC switch (16 GB)
  2. create zone and assign the LUNS to it from V7000.
  3. reboot the OS

  Hi Canonical,

  Can you please include these 2 commits to the lpfc driver on 17.04 and 16.04 HWE ?
  They've just been applied on mainline as of 4.11-rc1.

  The first resolves this problem, and the second prevents cache/DMA
  consistency problems which is likely to be hit in the future with this
  higher-performance adapter.

  I already asked for both patches to be flagged for stable kernels.

  [1] 8ea73db486cda442f0671f4bc9c03a76be398a28 lpfc: Correct WQ creation for pagesize 
  [2] 6b3b3bdb83b4ad51252d21bb13596db879e51850 lpfc: Add missing memory barrier

  Thank you.
