On HP M800 server cartridge we want to prevent irqbalance from running because it causes degradation in network throughput.
SRU TEMPLATE
============
[Impact]
* With irqbalance running on Slayton (HP M800 server) it degrades network performance.
[Testcase]
* To recreate this network performance degradation you need to execute the SRIO testcases provided by TI.
* After applying the patch run irqbalance command and it should emit a message to /var/log/syslog: May 7 19:56:13 ms10-18n3-slayton ./irqbalance: Balancing is ineffective on HP ProLiant m800 Server Cartridge. and exit gracefully.
[Regression Potential]
* None, this change is limited to HP M800 server cartridge |

[ SRU EXCEPTION REQUEST ]
A fix to this bug is limited in scope to 14.04 (Trusty) release. TI does not plan to support the Keystone II based Slayton platform beyond 14.04. TI has not upstreamed any kernel patches for this platform, instead, canonical is maintaining a 3.13 based linux-keystone flavor kernel to support Slayton. TI would be required to upstream all patches related to keystone II and Slayton if they need to extend support for their platform past 14.04. Therefore, the scope of this patch would also be limited to 14.04, and we request an exception from the SRU team to accept this patch in 14.04.
