net/vhost: fix socket file deleted on stop
If you create a vhost server device, it doesn't create the actual datagram
socket until you call .dev_start(). If you call .dev_stop() is also
deletes those sockets. For QEMU clients, this is a problem since QEMU
doesn't know how to re-attach to datagram sockets that have gone away.

uint16_t rte_eth_tx_prepare(uint8_t port_id, uint16_t queue_id,

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

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.

ethdev: introduce generic flow API
This new API supersedes all the legacy filter types described in
rte_eth_ctrl.h. It is slightly higher level and as a result relies more on
PMDs to process and validate flow rules.
Benefits:
- A unified API is easier to program for, applications do not have to be
written for a specific filter type which may or may not be supported by
the underlying device.
- The behavior of a flow rule is the same regardless of the underlying
device, applications do not need to be aware of hardware quirks.
- Extensible by design, API/ABI breakage should rarely occur if at all.
- Documentation is self-standing, no need to look up elsewhere.
Existing filter types will be deprecated and removed in the near future.

already configured queues will still use the old one. And if the old
