Thomas Monjalon de8d8ef4e9 doc: announce removal of ethdev flow director API
The flow director config, part of the legacy filtering API,
was marked as deprecated last year.
A separate notice is added to make clear that these specific structs
will be removed as well in DPDK 20.11, as the rest of the legacy
filtering API.

Thomas Monjalon 08016d67c5 doc: announce removal of legacy ethdev filtering API
Deprecation of rte_eth_dev_filter_ctrl() was announced in 2016,
and confirmed last year by avoiding include of rte_eth_ctrl.h.
After 4 years, it is time to complete the removal of the API
which is replaced with rte_flow.

Thomas Monjalon 7efbaa7b4e doc: announce ethdev port freeing on close operation
Since DPDK 18.11, some drivers are migrating to a new behaviour,
releasing port resources on close.
The temporary flag RTE_ETH_DEV_CLOSE_REMOVE triggers this new mode
in the migrated drivers.
After 2 years, the flag and the old behaviour will be removed.
Last drivers not migrated will have to complete the switch.

David Marchand 2c8d102161 doc: announce PCI resources map API removal
The PCI resources map API (pci_map_resource/pci_unmap_resource) was
imposing use of Unix mmap flags while it does not make sense on Windows.
This API was only used to internally setup PCI devices in the PCI bus
driver and has no known external users.

Announce its removal in 20.11 with its associated structures.

The workaround implemented in the commit 9d2b245937 ("pci: keep API
compatibility with mmap values") will be removed at the same time.

Somnath Kotur 48d1c589dd net/bnxt: fix flow counter query
OVS-DPDK seems to set the reset bit for every flow query. Honor
the bit by resetting the SW counter values after assigning them.
Also set the 'hit' bit only if the counter value retrieved by HW
is non-zero.
While querying flow stats, use max possible entries in the fc table scan
for valid entries instead of active entries as the active entry can be in
any slot in the table.

This is a critical fix for OVS-DPDK flow aging.

Matan Azrad 118494d3ad vdpa/mlx5: fix virtio queue unset
When a virtq is destroyed, the SW should be able to continue the virtq
processing from where the HW stopped.

The current destroy behavior in the driver saves the virtq state (used
and available indexes) only when LM is requested.
So, when LM is not requested the queue state is not saved and the SW
indexes stay invalid.

Save the virtq state in the virtq destroy process.

Sarosh Arif ce6b8c3154 examples: fix port mask parsing failure handling
Giving invalid or zero portmask as command line option to
these applications will have an unexpected response.
The reason behind this is that the return value of function
that parses portmask is stored in a variable whose datatype is
unsigned int, hence returning -1 in case of zero or
invalid portmask causes an unexpected behaviour.
If we return 0 instead of -1 this issue can be resolved.

Maxime Coquelin 3d4cd4be57 net/vhost: fix interrupt mode
At .new_device() time, only the first vring pair is
now ready, other vrings are configured later.

Problem is that when application will setup and enable
interrupts, only the first queue pair Rx interrupt will
be enabled.

This patches fixes the issue by setting the number of
max interrupts to the number of Rx queues that will be
later initialized. Then, as soon as a Rx vring is ready
and interrupt enabled by the application, it removes the
corresponding uninitialized epoll event, and installs a
new one with the valid FD.

Maxime Coquelin e97958398b net/vhost: fix queue update
Now that the vhost library saves the guest notifications
enablement value in its virtqueues metadata, it is not
necessary to do it in the vring_state_changed callback.

One effect of the patch is also to prevent possible
deadlock happening in vhost library.

Maxime Coquelin b53a497294 vhost: fix guest notification setting
If rte_vhost_enable_guest_notification is called before
the virtqueue is ready, the configuration is lost.

This patch fixes this by saving the guest notification
enablement value requested by the application, and apply
it before the virtqueue is made ready to the application.

Viacheslav Ovsiienko 5ce13f1acd app/testpmd: fix timestamp init in txonly mode
The testpmd application forwards data in multiple threads.
In the txonly mode the Tx timestamps must be initialized
on per thread basis to provide phase shift for the packet
burst being sent. This per thread initialization was performed
on zero value of the variable in thread local storage and
happened only once after testpmd forwarding start. Executing
"start" and "stop" commands did not cause thread local variables
zeroing and wrong timestamp values were used.
