[PATCH V2 libibverbs 0/7] RSS support

Hi Doug,

Sending V2 to align the map file with the GCC syntax, details below.
No other changes from V1.

The series was tested successfully with mlx5 driver (lib, kernel) and can be
accessed also from my openfabrics GIT at:
git://openfabrics.org/~yishaih/libibverbs.git branch: rss_v2

This patch-set exposes to user space the required objects and verbs in order to
allow verbs based solution to utilize the RSS offload capability.

The kernel part for the 5 first patches was already accepted into 4.8, the
capabilities patch (#6) was sent few weeks ago into 4.9, reviewed by Sagi
Grimberg and waits to your acceptance. The last patch adds and updates relevant
man pages.

In General:
RSS (Receive Side Scaling) technology allows to spread incoming 
traffic between different receive descriptor queues.
Assigning each queue to different CPU core allows to better load 
balance the incoming traffic and improve performance.

Extra details can be found in each commit message. 

Patches:
#1: Introduces Work Queue object and its verbs.
#2: Introduces Receive Work Queue indirection table and its verbs.
#3: Extends create QP to get a Receive-Work-Queue-indirection table.
#4: Extends create QP to get RX hash data.
#5: Tracks asynchronous events on a work queue.
#6: Exposes RSS related capabilities.
#7: Updates man pages for RSS usage.

Changes from V1:
patch #1: Align the map file around IBVERBS_1.3 to match the GCC syntax as described in below wiki:
          https://gcc.gnu.org/wiki/SymbolVersioning.

Changes from V0:
patches 1 & 2: Use IBVERBS_1.3 as the symbol label.
