The issue is the data/function pointer may vary from different processes,
and the old used to do one time set (for primary process only). That
said, the function pointer the secondary process saw is actually from the
primary process space. Accessing it could likely result to a crash.
Kudos to the last patches, we now be able to maintain those info that may
vary among different process locally, meaning every process could have its

this patch does:
- remap the PCI (IO port for legacy device and memory map for modern

vtpci_ops should be different among different processes.
Take virtio PMD as example, the vtpci_ops is set by the primary
process, based on its own process space. If we access that address
from the secondary process, that would be an illegal memory access,
A crash then might happen.
To make the multiple process model work, we need store the vtpci_ops
in local memory but not in a shared memory. This is what the patch
does: a local virtio_hw_internal array of size RTE_MAX_ETHPORTS is
allocated. This new structure is used to store all these kind of

- vtpci_ops
- rte_pci_ioport
- virtio pci mapped memory, such as common_cfg.

ethdev: fix port data mismatched in multiple process model
Assume we have two virtio ports, 00:03.0 and 00:04.0. The first one is
managed by the kernel driver, while the later one is managed by DPDK.
Now we start the primary process. 00:03.0 will be skipped by DPDK virtio
PMD driver (since it's being used by the kernel). 00:04.0 would be
successfully initiated by DPDK virtio PMD (if nothing abnormal happens).
After that, we would get a port id 0, and all the related info needed
by virtio (virtio_hw) is stored at rte_eth_dev_data[0].
Then we start the secondary process. As usual, 00:03.0 will be firstly
probed. It firstly tries to get a local eth_dev structure for it (by
rte_eth_dev_allocate):
port_id = rte_eth_dev_find_free_port();
...
eth_dev = &rte_eth_devices[port_id];
eth_dev->data = &rte_eth_dev_data[port_id];
...
return eth_dev;
Since it's a first PCI device, port_id will be 0. eth_dev->data would
then point to rte_eth_dev_data[0]. And here things start going wrong,
as rte_eth_dev_data[0] actually stores the virtio_hw for 00:04.0.
That said, in the secondary process, DPDK will continue to drive PCI
device 00.03.0 (despite the fact it's been managed by kernel), with
the info from PCI device 00:04.0. Which is wrong.
The fix is to attach the port already registered by the primary process.
That is, iterate the rte_eth_dev_data[], and get the port id who's PCI
ID matches the current PCI device.
This would let us maintain same port ID for the same PCI device, keeping
the chance of referencing to wrong data minimal.

ethdev: add Tx preparation
Added API for `rte_eth_tx_prepare`
uint16_t rte_eth_tx_prepare(uint8_t port_id, uint16_t queue_id,
struct rte_mbuf **tx_pkts, uint16_t nb_pkts)
Added fields to the `struct rte_eth_desc_lim`:
uint16_t nb_seg_max;
/**< Max number of segments per whole packet. */
uint16_t nb_mtu_seg_max;
/**< Max number of segments per one MTU */
These fields can be used to create valid packets according to the
following rules:
* For non-TSO packet, a single transmit packet may span up to
"nb_mtu_seg_max" buffers.
* For TSO packet the total number of data descriptors is "nb_seg_max",
and each segment within the TSO may span up to "nb_mtu_seg_max".
Added functions:
int
rte_validate_tx_offload(struct rte_mbuf *m)
to validate general requirements for tx offload set in mbuf of packet
such a flag completness. In current implementation this function is
called optionaly when RTE_LIBRTE_ETHDEV_DEBUG is enabled.
int rte_net_intel_cksum_prepare(struct rte_mbuf *m)
to prepare pseudo header checksum for TSO and non-TSO tcp/udp packets
before hardware tx checksum offload.
- for non-TSO tcp/udp packets full pseudo-header checksum is
counted and set.
- for TSO the IP payload length is not included.
int
rte_net_intel_cksum_flags_prepare(struct rte_mbuf *m, uint64_t ol_flags)
this function uses same logic as rte_net_intel_cksum_prepare, but
allows application to choose which offloads should be taken into
account, if full preparation is not required.
PERFORMANCE TESTS
-----------------
This feature was tested with modified csum engine from test-pmd.
The packet checksum preparation was moved from application to Tx
preparation step placed before burst.
We may expect some overhead costs caused by:
1) using additional callback before burst,
2) rescanning burst,
3) additional condition checking (packet validation),
4) worse optimization (e.g. packet data access, etc.)
We tested it using ixgbe Tx preparation implementation with some parts
disabled to have comparable information about the impact of different
parts of implementation.
IMPACT:
1) For unimplemented Tx preparation callback the performance impact is
negligible,
2) For packet condition check without checksum modifications (nb_segs,
available offloads, etc.) is
14626628/
14252168 (~2.62% drop),
3) Full support in ixgbe driver (point 2 + packet checksum
initialization) is
14060924/
13588094 (~3.48% drop)

ethdev: fix extended statistics name index
The function rte_eth_xstats_get() return an array of tuples (id,
value). The value is the statistic counter, while the id references a
name in the array returned by rte_eth_xstats_get_name().
Today, each 'id' returned by rte_eth_xstats_get() is equal to the index
in the returned array, making this value useless. It also prevents a
driver from having different indexes for names and value, like in the
example below:
rte_eth_xstats_get_name() returns:
0: "rx0_stat"
1: "rx1_stat"
2: ...
7: "rx7_stat"
8: "tx0_stat"
9: "tx1_stat"
...
15: "tx7_stat"
rte_eth_xstats_get() returns:
0: id=0, val=<stat> ("rx0_stat")
1: id=1, val=<stat> ("rx1_stat")
2: id=8, val=<stat> ("tx0_stat")
3: id=9, val=<stat> ("tx1_stat")
This patch fixes the drivers to set the 'id' in their ethdev->xstats_get()
(except e1000 which was already doing it), and fixes ethdev by not setting
the 'id' field to the index of the table for pmd-specific stats: instead,
they should just be shifted by the max number of generic statistics.

app/testpmd: support flow bit-field
Several rte_flow structures expose bit-fields that cannot be set in a
generic fashion at byte level. Add bit-mask support to handle them.

app/testpmd: add flow item spec prefix length
Generating bit-masks from prefix lengths is often more convenient than
providing them entirely (e.g. to define IPv4 and IPv6 subnets).
This commit adds the "prefix" operator that assigns generated bit-masks to
any pattern item specification field.

app/testpmd: add flow item spec handler
Add parser code to fully set individual fields of pattern item
specification structures, using the following operators:
- fix: sets field and applies full bit-mask for perfect matching.
- spec: sets field without modifying its bit-mask.
- last: sets upper value of the spec => last range.
- mask: sets bit-mask affecting both spec and last from arbitrary value.
