Introduce a new PMD driver which names spnic.
Now, this driver only implements module entry
without doing anything else.

CLOCK_MONOTONIC_RAW was defined in Linux.2.6.28
DPDK does not support any kernels that old, so the #ifdef is not needed.

If all you want is jiffie accuracy, you could use CLOCK_MONOTONIC_COARSE.
+#define jiffies clock_gettime_ms()
+#define msecs_to_jiffies(ms) (ms)
+#define time_before(now, end) ((now) < (end))
Does that simple version of the macro work right if jiffies wraps around?
Less of an issue on 64 bit platforms...
The kernel version is effectively.
#define time_before(now, end) ((long)((now) - (end)) < 0)

I did not get your point: CLOCK_MONOTONIC is more accurate than
CLOCK_MONOTONIC_COARSE, right?

CLOCK_MONOTONIC ends up using the TSC counter and values in the
shared page (VDSO) to compute time accurately.
CLOCK_MONOTONIC_COARSE is faster and good enough if you only
want ms accuracy. It just reads a value from shared page
and avoids the TSC instruction.

OK. Got it. Thanks. Will be included in the next version.

To: dev; +Cc: songyl, yanling.song, yanggan, ferruh.yigit
This commit introduce cmdq and work queue which can be used to
send bulk message data(up to 2KB) to hardware. cmdq provides a
mechanism to encapsulate the message to be sent and handle the
response data or status. work queue is used to manager the wqe
in which includes message data buffer description, ctrl info,
header info and response message data buffer. This patch
implements the initialization and data structure.

To: dev; +Cc: songyl, yanling.song, yanggan, ferruh.yigit
This commits add hardware info initialization, including
that device capability initialization, common feature
negotiation, and two interfaces spnic_get_board_info(),
spnic_get_mgmt_version() to get hardware info and
firmware version.

To: dev; +Cc: songyl, yanling.song, yanggan, ferruh.yigit
This commit adds interfaces to add/remove MAC addresses
and registers related ops to struct eth_dev_ops. Furthermore,
this commit adds callback to handle link events.

To: dev; +Cc: songyl, yanling.song, yanggan, ferruh.yigit
This patch defines a wqe data structure for hardware to
learn the sge info and offload info of packet. Furthermore,
this commit implements the interfaces to fill wqe with DPDK mbuf.

This patch implements rx_pkt_burst() and tx_pkt_burst()
to hanld IO packets.
For Tx packets, this commit implements parsing ol_flags of
mbuf and filling those offload info on wqe so that hardware
can process the packets correctly. Furthermore, this commit
allocates a mempool to cover scenes with too many mbufs for
one packet.
For Rx packets, this commit implements filling ol_flags of
mbuf and rearming new mbuf and rq wqe.

To: dev; +Cc: songyl, yanling.song, yanggan, ferruh.yigit
This commit supports VFIO interrupt for Rx queue and
asynchronous event, and implements rx_queue_intr_disable()
and rx_queue_intr_enable() to disable/enable the interrupt
of specified Rx queue.

This commit support starting or stopping a specified Rx/Tx queue
For Rx queue:
when startting rx queue, mbuf will be allocated and fill rq
wqe with mbuf info, then add the qid to indirect table of RSS.
if the first rx queue is started, the valid bit in function table
will be setted so that the packets can be received to host.
when stopping rx queue, the PMD driver will poll the rx queue
until it is empty and release the mbuf, then the PMD driver will
remove the qid for RSS indirect table. if the last rx queue is
stopped, the valid bit in function table will be cleared.
For Rx queue:
when stopping tx queue, the PMD driver will wait until all tx
packets are sent and then releases all mbuf.

+SPNIC Poll Mode Driver
+======================
+
+The spnic PMD (**librte_net_spnic**) provides poll mode driver support
+for 25Gbps/100Gbps SPNxxx Network Adapters.
+
+
+Features
+--------
+
+- Multiple queues for TX and RX
+- Receiver Side Scaling（RSS）
+- RSS supports IPv4, IPv6, TCPv4, TCPv6, UDPv4 and UDPv6, use inner type for VXLAN as default
+- MAC/VLAN filtering
+- Checksum offload
+- TSO offload
+- LRO offload
+- Promiscuous mode
+- Port hardware statistics
+- Link state information
+- Link flow control(pause frame)
+- Scattered and gather for TX and RX
+- SR-IOV - Partially supported VFIO only
+- VLAN filter and VLAN offload
+- Allmulticast mode
+- MTU update
+- Unicast MAC filter
+- Multicast MAC filter
+- Set Link down or up
+- FW version
+- Multi arch support: x86_64, ARMv8.
+
+Prerequisites
+-------------
+
+- Learning about SPNIC using
+ `<xx card introduce>`_.
+
+- Getting the latest product documents and software supports using
+ `<Website to support>`_.
+
+- Follow the DPDK :ref:`Getting Started Guide for Linux <linux_gsg>` to setup the basic DPDK environment.
+
+
+Driver compilation and testing
+------------------------------
+
+Refer to the document :ref:`compiling and testing a PMD for a NIC <pmd_build_and_test>`
+for details.
+
+It is highly recommended to upgrade the spnic driver and firmware to avoid the compatibility issues,
+and check the work mode with the latest product documents.
+
