When stop device, should disable interrupt of FDIR but not

This commit introduce rte_smp_mb(), rte_smp_wmb() and rte_smp_rmb(), in
order to enable memory barriers between lcores.
The patch does not provide any functional change for IA, the goal is to
have infrastructure for weakly ordered machines like ARM to work on DPDK.

Its a RFC patch and I am not sure about the ordering behavior in
tile and ppc_64 architecture so kept as rte_compiler_barrier()
as existing code.
If it need changes in tile and ppc_64 then let me know, I will send the
updated patch.
Jerin Jacob (1):
Introduce rte_smp_*mb() for memory
Is there a way where we can just define the fields that ought to be there in
the mbuf structure, but the position and size is implementation dependent ? The
application can provide "mbuf_impl.h" that contains mbuf_rte fields in the
order that seems appropriate to application.

Per queue rx interrupt works on vfio, however on uio, all rx queues share one
interrupt vector.
v4 change:
- remove redundancy condition check
v3 change:
- macro change according the EAL
- add doc update follow on the code
When igb runs as a PF, mbox interrupt is prerequisite to make VF start normally.
And PF sometimes won't 'dev_start', so the mbox interrupt register during
'dev_init' is required.
The patch rolls back the interrupt register for mbox,lsc to the 'dev_init'.
As UIO doesn't support multiple vector,
As ixgbe vf doesn't support lsc, the patch removes those unused code.
In addition, it does some tiny cleanup.

The change in tsc value from rte_rdtsc() needs to be multiplied by the scale to
convert from clocks to get change in seconds.
For example from below:
elapse_us = (rte_rdtsc() - entry->tsc_first_packet) * flow_time_scale_us;
The bit rate requires the number of bytes passed in the time period

The patch adds condition check to avoid enable nothing.
In disable state, both max_intr and nb_efd are zero.

According to the VFIO interrupt mapping, the interrupt vector id for rxq starts
from RX_VEC_START.
It doesn't impact the UIO cases.
v3 change:
- macro renaming according to the EAL change

During VFIO_DEVICE_SET_IRQS, the previous order is {Q0_fd, ... Qn_fd, misc_fd}.
The vector number of misc is indeterminable which is ugly to some NIC(e.g.
i40e, fm10k).
The patch adjusts the order in {misc_fd, Q0_fd, ... Qn_fd}, always reserve the
first vector to misc interrupt.
v3 changes:
-
v3 change:
- rename MISC_VEC_ID and RX_VEC_START
- add bsdapp dummy
- split cleanup and fix patches
- merge doc update along with code change
v2 change:
- rework to depend on one previous patch
patch http://dpdk.org/dev/patchwork/patch/7504/
- always set DIS_AUTOMASK_* bit in PF
