Hi All,
Please hold on for review as this version is not aligned with latest spec
changes for input coloring mechanism.
I will be sending the next version soon.

LWM(limit watermark) is per RX queue attribute, when RX queue fullness reach
the LWM limit, HW sends an event to dpdk application.
Host shaper can configure shaper rate and lwm-triggered for a host port.
The shaper limits the rate of traffic from host port to wire port.
If lwm-triggered is enabled
Add lwm(Limit WaterMark) field to Rxq object which indicates the percentage
of RX queue size used by HW to raise LWM event to the user.
Allow LWM setting in modify_rq command.
Allow the LWM configuration dynamically by adding RDY2RDY state change.

LWM(limit watermark) describes the fullness of a Rx queue. If the Rx
queue fullness is above LWM, the device will trigger the event
RTE_ETH_EVENT_RX_LWM.
LWM is defined as a percentage of Rx queue size with valid value of
[0,99].
Setting LWM to 0 means disable it, which is the default.
When transla
Add mlx5 specific LWM(limit watermark) configuration and query handler.
While the Rx queue fullness reaches the LWM limit, the driver catches
an HW event and invokes the user callback.
The query handler finds the next RX queue with pending LWM event
if any, starting from the given RX queue index.
When LWM meets RQ WQE, the kernel driver raises an event to SW.
Use devx event_channel to catch this and to notify the user.
Allocate this channel per shared device.
The channel has a cookie that informs the specific event port and queue.

There are many duplicate code of creating and initializing rte_intr_handle.
Add a new mlx5_os API to do this, replace all PMD related code with this
API.

Host port shaper can be configured with QSHR(QoS Shaper Host Register).
Add check in build files to enable this function or not.
The host shaper configuration affects all the ethdev ports belonging to the
same host port.
Host shaper can configure shaper rate and lwm-triggered for a host port.
The
Add command line options to support LWM per-rxq configure.
- Command syntax:
set port rxq lwm
mlx5 set port host_shaper lwm_triggered <0|1> rate
- Example commands:
To configure LWM as 30% of rxq size on port 1 rxq 0:
testpmd> set port 1 rxq 0 lwm 30
To disable LWM on port 1 rxq 0:
testp
