With the patch applied the number of instruction events is 1% less and
number of mispredicted branch events is 5% less under multistream TCP

76a869385c sfxge: Remove interrupt self-test code 
It's not currently used; it didn't build on 32-bit and the previous build fix
is incorrect.  If we really implement self-tests we can do this again
properly.

e948693ed7 Add the sfxge(4) device driver, providing support for 10Gb Ethernet adapters 
based on Solarflare SFC9000 family controllers.  The driver supports jumbo
frames, transmit/receive checksum offload, TCP Segmentation Offload (TSO),
Large Receive Offload (LRO), VLAN checksum offload, VLAN TSO, and Receive Side
Scaling (RSS) using MSI-X interrupts.
