net/ice/base: support configuring device in double VLAN mode

In order to support configuring the device in Double VLAN Mode (DVM),
the DDP and FW have to support DVM. If both support DVM, the PF
that downloads the package needs to update the default recipes and set
the VLAN mode. This is done in ice_set_dvm().

In order to support updating the default recipes in DVM add support
for updating an existing switch recipe's lkup_idx and mask.
This is done by first calling the get recipe AQ (0x0292) with the
desired recipe ID. Then, if that is successful update one of the lookup
indices (lkup_idx) and its associated mask if the mask is valid
otherwise the already existing mask will be used.

net/ice/base: add VLAN TPID for VLAN filters

Currently VLAN filters via RID4 are only based on VLAN ID. However, with
incoming support for Double VLAN Mode (DVM), the driver needs to be able
to support filtering on VLAN ID + VLAN TPID (i.e. 0x8100, 0x88a8, etc.).
Add support for this by adding two fields to the ice_fltr_info
structure. First, add the tpid_valid field so the code can determine
whether or not to overwrite the default 0x8100 value for programming

examples/eventdev: move ethdev stop to the end

Move eth stop code from "signal_handler" function to the end of "main"
function. There are two reasons for this:

First, this improves code maintenance and makes code look simple and
clear. Based on this change, after receiving the interrupt signal,
"fdata->done" is set as 1. Then the main thread will wait all worker
lcores to jump out of the loop. Finally, the main thread will stop and
then close eth dev port.

Second, for older version, the main thread first stops eth dev port and
then waits the end of worker lcore. This may cause errors because it may
stop the eth dev port which worker lcores are using. This moving change
can fix this by waiting all worker threads to exit and then stop the
eth dev port.

In the meanwhile, remove wmb in signal_handler.

This is because when the main lcore receive the stop signal, it stores 1
into fdata->done. And then the worker lcores load "fdata->done" and jump
out of the loop to stop running. Nothing should be stored after updating
fdata->done, so the wmb is unnecessary.

3 years agotest/distributor: fix return buffer queue overload
Lukasz Wojciechowski [Tue, 19 Jan 2021 03:59:10 +0000 (04:59 +0100)]
test/distributor: fix return buffer queue overload

The distributor library implementation uses a cyclic queue to store
packets returned from workers. These packets can be later collected
with rte_distributor_returned_pkts() call.
However the queue has limited capacity. It is able to contain only
127 packets (RTE_DISTRIB_RETURNS_MASK).

Big burst tests sent 1024 packets in 32 packets bursts without waiting
until they are processed by the distributor. In case when tests were
run with big number of worker threads, it happened that more than
127 packets were returned from workers and put into cyclic queue.
This caused packets to be dropped by the queue, making them impossible
to be collected later with rte_distributor_returned_pkts() calls.
However the test waited for all packets to be returned infinitely.

This patch fixes the big burst test by not allowing more than
queue capacity packets to be processed at the same time, making
impossible to drop any packets.
It also cleans up duplicated code in the same test.
