William Tu d1c7029a52 net/e1000: build on Windows 
This patch enables building the e1000 driver for Windows.
I tested using two Windows VM on top of VMware Fusion,
creating two e1000 devices with device ID 0x10D3 (8274L),
verifying rx/tx works correctly using dpdk-testpmd.exe
rxonly and txonly mode.

Removed Items
-------------
.. This section should contain removed items in this release. Sample format:
* Add a short 1-2 sentence description of the removed item
in the past tense.
This section is a comment. Do not overwrite or remove it.
Also, make sure to start the actual text at the margin.
=======================================================
* eal: Removed the deprecated function ``rte_get_master_lcore()``
and the iterator macro ``RTE_LCORE_FOREACH_SLAVE``.
* eal: The old api arguments that were deprecated for
blacklist/whitelist are removed. Users must use the new
block/allow list arguments.
* mbuf: Removed offload flag ``PKT_RX_EIP_CKSUM_BAD``.
``PKT_RX_OUTER_IP_CKSUM_BAD`` should be used as a replacement.
* ethdev: Removed the port mirroring API. A more fine-grain flow API
action ``RTE_FLOW_ACTION_TYPE_SAMPLE`` should be used instead.
The structures ``rte_eth_mirror_conf`` and ``rte_eth_vlan_mirror`` and
the functions ``rte_eth_mirror_rule_set`` and
``rte_eth_mirror_rule_reset`` along with the associated macros
``ETH_MIRROR_*`` are removed.
* ethdev: Removed ``rte_eth_rx_descriptor_done`` API function and its
driver callback. It is replaced by the more complete function
``rte_eth_rx_descriptor_status``.
* ethdev: Removed deprecated ``shared`` attribute of the
``struct rte_flow_action_count``. Shared counters should be managed
using indirect actions API (``rte_flow_action_handle_create`` etc).
* i40e: Removed i40evf driver.
iavf already became the default VF driver for i40e devices,
so there is no need to maintain i40evf.
API Changes
-----------
.. This section should contain API changes. Sample format:
* sample: Add a short 1-2 sentence description of the API change
which was announced in the previous releases and made in this release.
Start with a scope label like "ethdev:".
Use fixed width quotes for ``function_names`` or ``struct_names``.
Use the past tense.
This section is a comment. Do not overwrite or remove it.
Also, make sure to start the actual text at the margin.
=======================================================
* kvargs: The experimental function ``rte_kvargs_strcmp()`` has been
removed. Its usages have been replaced by a new function
``rte_kvargs_get_with_value()``.
* cmdline: ``cmdline_stdin_exit()`` now frees the ``cmdline`` structure.
Calls to ``cmdline_free()`` after it need to be deleted from applications.
* cmdline: Made ``cmdline`` structure definition hidden on Linux and FreeBSD.
* cmdline: Made ``rdline`` structure definition hidden. Functions are added
to dynamically allocate and free it, and to access user data in callbacks.
* mempool: Added ``RTE_MEMPOOL_F_NON_IO`` flag to give a hint to DPDK components
that objects from this pool will not be used for device IO (e.g. DMA).
* mempool: The mempool flags ``MEMPOOL_F_*`` will be deprecated in the future.
Newly added flags with ``RTE_MEMPOOL_F_`` prefix should be used instead.
* mempool: Helper macro ``MEMPOOL_HEADER_SIZE()`` is deprecated.
The replacement macro ``RTE_MEMPOOL_HEADER_SIZE()`` is internal only.
* mempool: Macro to register mempool driver ``MEMPOOL_REGISTER_OPS()`` is
deprecated. Use replacement ``RTE_MEMPOOL_REGISTER_OPS()``.
* mempool: The mempool API macros ``MEMPOOL_PG_*`` are deprecated and
will be removed in DPDK 22.11.
* net: Renamed ``s_addr`` and ``d_addr`` fields of ``rte_ether_hdr`` structure
to ``src_addr`` and ``dst_addr``, respectively.
* net: Added ``version`` and ``ihl`` bit-fields to ``struct rte_ipv4_hdr``.
Existing ``version_ihl`` field is kept for backward compatibility.
* ethdev: Added items and actions ``PORT_REPRESENTOR``, ``REPRESENTED_PORT`` to
flow API.
* ethdev: Deprecated items and actions ``PF``, ``VF``, ``PHY_PORT``, ``PORT_ID``.
Suggested items and actions ``PORT_REPRESENTOR``, ``REPRESENTED_PORT`` instead.
* ethdev: Deprecated the use of attributes ``ingress`` / ``egress`` combined
with ``transfer``. See items ``PORT_REPRESENTOR``, ``REPRESENTED_PORT``.
* ethdev: ``rte_flow_action_modify_data`` structure updated, immediate data
array is extended, data pointer field is explicitly added to union, the
action behavior is defined in more strict fashion and documentation updated.
The immediate value behavior has been changed, the entire immediate field
should be provided, and offset for immediate source bitfield is assigned
from destination one.
* cryptodev: The API rte_cryptodev_pmd_is_valid_dev is modified to
rte_cryptodev_is_valid_dev as it can be used by the application as
well as PMD to check whether the device is valid or not.
* cryptodev: The rte_cryptodev_pmd.* files are renamed as cryptodev_pmd.*
as it is for drivers only and should be private to DPDK, and not
installed for app use.
* cryptodev: A ``reserved`` byte from structure ``rte_crypto_op`` was
renamed to ``aux_flags`` to indicate warnings and other information from
the crypto/security operation. This field will be used to communicate
events such as soft expiry with IPsec in lookaside mode.
* cryptodev: The field ``dataunit_len`` of the ``struct rte_crypto_cipher_xform``
moved to the end of the structure and extended to ``uint32_t``.
* cryptodev: The structure ``rte_crypto_vec`` was updated to add ``tot_len``
field to support total buffer length to facilitate protocol offload case.
* cryptodev: The structure ``rte_crypto_sym_vec`` was updated to add
``dest_sgl`` to support out of place processing.
* bbdev: Added device info related to data byte endianness processing.
* eventdev: Moved memory used by timer adapters to hugepage. This will prevent
TLB misses if any and aligns to memory structure of other subsystems.
ABI Changes
-----------
.. This section should contain ABI changes. Sample format:
* sample: Add a short 1-2 sentence description of the ABI change
which was announced in the previous releases and made in this release.
Start with a scope label like "ethdev:".
Use fixed width quotes for ``function_names`` or ``struct_names``.
Use the past tense.
This section is a comment. Do not overwrite or remove it.
Also, make sure to start the actual text at the margin.
=======================================================
* ethdev: Input parameters for ``eth_rx_queue_count_t`` was changed.
Instead of pointer to ``rte_eth_dev`` and queue index, now it accepts pointer
to internal queue data as input parameter. While this change is transparent
to user, it still counts as an ABI change, as ``eth_rx_queue_count_t``
is used by public inline function ``rte_eth_rx_queue_count``.
* ethdev: Made ``rte_eth_dev``, ``rte_eth_dev_data``, ``rte_eth_rxtx_callback``
private data structures. ``rte_eth_devices[]`` can't be accessed directly
by user any more. While it is an ABI breakage, this change is intended
to be transparent for both users (no changes in user app is required) and
PMD developers (no changes in PMD is required).
* security: ``rte_security_set_pkt_metadata`` and ``rte_security_get_userdata``
routines used by inline outbound and inline inbound security processing were
made inline and enhanced to do simple 64-bit set/get for PMDs that do not
have much processing in PMD specific callbacks but just 64-bit set/get.
This avoids a per packet function pointer jump overhead for such PMDs.
* security: A new option ``iv_gen_disable`` was added in structure
``rte_security_ipsec_sa_options`` to disable IV generation inside PMD,
so that application can provide its own IV and test known test vectors.
* security: A new option ``tunnel_hdr_verify`` was added in structure
``rte_security_ipsec_sa_options`` to indicate whether outer header
verification need to be done as part of inbound IPsec processing.
* security: A new option ``udp_ports_verify`` was added in structure
``rte_security_ipsec_sa_options`` to indicate whether UDP ports
verification need to be done as part of inbound IPsec processing.
* security: A new structure ``rte_security_ipsec_lifetime`` was added to
replace ``esn_soft_limit`` in IPsec configuration structure
``rte_security_ipsec_xform`` to allow applications to configure SA soft
and hard expiry limits. Limits can be either in number of packets or bytes.
* security: The new options ``ip_csum_enable`` and ``l4_csum_enable`` were added
in structure ``rte_security_ipsec_sa_options`` to indicate whether inner
packet IPv4 header checksum and L4 checksum need to be offloaded to
security device.
* security: A new structure ``esn`` was added in structure
``rte_security_ipsec_xform`` to set an initial ESN value. This permits
application to start from an arbitrary ESN value for debug and SA lifetime
enforcement purposes.
* security: A new structure ``udp`` was added in structure
``rte_security_ipsec_xform`` to allow setting the source and destination ports
for UDP encapsulated IPsec traffic.
* bbdev: Added capability related to more comprehensive CRC options,
shifting values of the ``enum rte_bbdev_op_ldpcdec_flag_bitmasks``.
* eventdev: New variables ``rx_event_buf_count`` and ``rx_event_buf_size``
were added in structure ``rte_event_eth_rx_adapter_stats`` to get additional
status.
* eventdev: A new structure ``rte_event_fp_ops`` has been added which is now used
by the fastpath inline functions. The structures ``rte_eventdev``,
``rte_eventdev_data`` have been made internal. ``rte_eventdevs[]`` can't be
accessed directly by user any more. This change is transparent to both
applications and PMDs.
* eventdev: Re-arranged fields in ``rte_event_timer`` to remove holes.
