In bnxt_hwrm_flash_nvram, before attempting to allocate a buffer
we are grabbing the rte_spinlock. And if the allocation fails we

This reverts the patch that enabled mbuf fast free.
There are two main reasons.
First, enic_fast_free_wq_bufs is broken. When
DEV_TX_OFFLOAD_MBUF_FAST_FREE is enabled, the driver calls this
function to free transmitted mbufs. This function currently does not
reset next and nb_segs. This is simply wrong as the fast-free flag
does not imply anything about next and nb_segs.
We could fix enic_fast_free_wq_bufs by making it to call
rte_pktmbuf_prefree_seg to reset the required fields. But, it negates
most of cycle saving.
Second, there are customer applications that blindly enable all Tx
offloads supported by the device. Some of these applications do not
satisfy the requirements of mbuf fast free (i.e. a single pool per
queue and refcnt = 1), and end up crashing or behaving badly.

Makefiles are updated with new test case lists.
Test cases are classified as -
P1 - Main test cases,
P2 - Cryptodev/driver test cases,
P3 - Perf test cases which takes longer than 10s,
P4 - Logging/Dump test cases.
Makefile is updated with different targets
for the above classified groups.
Test cases for different targets are listed accordingly.
Now that everything else is in place, we can run unit tests in a
different fashion to what they were running as before. Previously,
we had all autotests as part of groups (largely obtained through
trial and error) to ensure parallel execution while still limiting
amounts of memory used by those tests.
This is no longer necessary, and as of previous commit, all tests
are now in the same group (still broken into two categories). They
still run one-by-one though. Fix this by initializing child
processes in multiprocessing Pool initialization, and putting all
tests on the queue, so that tests are executed by the first idle
worker. Tests are also affinitized to different NUMA nodes using
taskset in a round-robin fashion, to prevent over-exhausting
memory on any given NUMA node.
Non-parallel tests are executed in similar fashion, but on a
separate queue which will have only one pool worker, ensuring
non-parallel execution.
Support for FreeBSD is also added to ensure that on FreeBSD, all
tests are run sequentially even for the parallel section.
Previously, all autotests were grouped into (seemingly arbitrary)
groups. The goal was to run all tests in parallel (so that autotest
finishes faster), but we couldn't just do it willy-nilly because
DPDK couldn't allocate and free hugepages on-demand, so we had to
find autotest groupings that could work memory-wise and still be
fast enough to not hold up shorter tests. The inflexibility of
memory subsystem has now been fixed for 18.05, so grouping
autotests is no longer necessary.
Thus, this commit moves all autotests into two groups -
parallel(izable) autotests, and non-arallel(izable) autotests
(typically performance tests). Note that this particular commit
makes running autotests dog slow because while the tests are now
in a single group, the test function itself hasn't changed much,
so all autotests are now run one-by-one, starting and stopping
the DPDK test application.
Improve code for filtering test groups. Also, move reading binary
symbols into filtering stage, so that tests that are meant to be
skipped are never attempted to be executed in the first place.
Before running tests, print out any tests that were skipped because
they weren't compiled.
Autotest runner was still using python 2-style print syntax. Fix
it by importing print function from the future, and fix the calls
to be python-3 style.
There are no reports defined for any test, so this codepath was
never triggered, but it's still wrong because it's referencing
variables that aren't there. Fix it by passing target into the
test function, and reference correct log variable.
Previously, printing was done using tuple syntax, which caused
output to appear as a tuple as opposed to being one string. Fix
this by using addition operator instead.
This patch adds a new function that is called
per every checked patch,
and alerts for new instances of rte_panic/rte_exit.
The check excludes comments, and alerts in the case
of a positive balance between additions and removals.

net/mlx5: add port ID pattern item to switch flow rules
This enables flow rules to match traffic coming from a different DPDK port
ID associated with the device (PORT_ID pattern item), mainly for the
convenience of applications that want to deal with a single port ID for all
flow rules associated with some physical device.
Testpmd example:
- Creating a flow rule on port ID 1 to consume all traffic from port ID 0
and direct it to port ID 2:
flow create 1 ingress transfer pattern port_id id is 0 / end actions
port_id id 2 / end
net/mlx5: add VLAN item and actions to switch flow rules
This enables flow rules to explicitly match VLAN traffic (VLAN pattern
item) and perform various operations on VLAN headers at the switch level
(OF_POP_VLAN, OF_PUSH_VLAN, OF_SET_VLAN_VID and OF_SET_VLAN_PCP actions).
Testpmd examples:
- Directing all VLAN traffic received on port ID 1 to port ID 0:
flow create 1 ingress transfer pattern eth / vlan / end actions
port_id id 0 / end
- Adding a VLAN header to IPv6 traffic received on port ID 1 and directing
it to port ID 0:
flow create 1 ingress transfer pattern eth / ipv6 / end actions
of_push_vlan ethertype 0x8100 / of_set_vlan_vid vlan_vid 42 /
port_id id 0 / end
This patch enables creation of rte_flow rules that direct matching traffic
to a different port (e.g. another VF representor) or drop it directly at
the switch level (PORT_ID and DROP actions).
Testpmd examples:
- Directing all traffic to port ID 0:
flow create 1 ingress transfer pattern end actions port_id id 0 / end
- Dropping all traffic normally received by port ID 1:
flow create 1 ingress transfer pattern end actions drop / end
Note the presence of the transfer attribute, which requests them to be
applied at the switch level. All traffic is matched due to empty pattern.
Because mlx5 switch flow rules are configured through Netlink (TC
interface) and have little in common with Verbs, this patch adds a separate
parser function to handle them.
- mlx5_nl_flow_transpose() converts a rte_flow rule to its TC equivalent
and stores the result in a buffer.
- mlx5_nl_flow_brand() gives a unique handle to a flow rule buffer.
- mlx5_nl_flow_create() instantiates a flow rule on the device based on
such a buffer.
- mlx5_nl_flow_destroy() performs the reverse operation.
These functions are called by the existing implementation when encountering
flow rules which must be offloaded to the switch (currently relying on the
transfer attribute).
