8d1a709b6f ethdev: move flexible filter type to e1000 driver
net/e1000 driver is the only user of the struct rte_eth_flex_filter
and helper defines.  Move it to the driver and use igb_ prefix
instead of rte_eth_.

35b1c68af2 ethdev: remove legacy EtherType filter type support
Instead of EtherType filter RTE flow API should be used.

Move corresponding definitions to ethdev internal driver API
since it is used by drivers internally.
Preserve RTE_ETH_FILTER_ETHERTYPE because of it as well.

fb4b7a131c vhost: fix guest/host physical address conversion
gpa_to_hpa() function almost always fails due to the wrong setup of
the binary tree search key. Since there has already been a similar
function gpa_to_first_hpa() available in the vhost, instead of fixing
the issue in its original logic, gpa_to_hpa() function is rewritten to
be a wrapper of the gpa_to_first_hpa() to avoid code redundancy.

1848b117cc app/testpmd: fix RSS key for flow API RSS rule
When a flow API RSS rule is issued in testpmd, device RSS key is changed
unexpectedly, device RSS key is changed to the testpmd default RSS key.

Consider the following usage with testpmd:
1. first, startup testpmd:
 testpmd> show port 0 rss-hash key
 RSS functions: all ipv4-frag ipv4-other ipv6-frag ipv6-other ip
 RSS key: 6D5A56DA255B0EC24167253D43A38FB0D0CA2BCBAE7B30B477CB2DA38030F
          20C6A42B73BBEAC01FA
2. create a rss rule
 testpmd> flow create 0 ingress pattern eth / ipv4 / udp / end \
          actions rss types ipv4-udp end queues end / end

3. show rss-hash key
 testpmd> show port 0 rss-hash key
 RSS functions: all ipv4-udp udp
 RSS key: 74657374706D6427732064656661756C74205253532068617368206B65792
          C206F76657272696465

This is because testpmd always sends a key with the RSS rule,
if user provides a key as part of the rule that key is used, if user
doesn't provide a key, testpmd default key is sent to the PMDs, which is
causing device programmed RSS key to be changed.

There was a previous attempt to fix the same issue [1], but it has been
reverted back [2] because of the crash when 'key_len' is provided
without 'key'.

This patch follows the same approach with the initial fix [1] but also
addresses the crash.

After change, testpmd RSS key is 'NULL' by default, if user provides a
key as part of rule it is used, if not no key is sent to the PMDs at all

c0d002aed9 gso: fix mbuf freeing responsibility
rte_gso_segment decreased refcnt of pkt by one, but
it is wrong if pkt is external mbuf, pkt won't be
freed because of incorrect refcnt, the result is
application can't allocate mbuf from mempool because
mbufs in mempool are run out of.

One correct way is application should call
rte_pktmbuf_free after calling rte_gso_segment to free
pkt explicitly. rte_gso_segment must not handle it, this
should be responsibility of application.

This commit changed rte_gso_segment in functional behavior
and return value, so the application must take appropriate
actions according to return values, "ret < 0" means it
should free and drop 'pkt', "ret == 0" means 'pkt' isn't
GSOed but 'pkt' can be transmitted as a normal packet,
"ret > 0" means 'pkt' has been GSOed into two or multiple
segments, it should use "pkts_out" to transmit these
segments. The application must free 'pkt' after call
rte_gso_segment when return value isn't equal to 0.

bd117d62a6 eal/windows: fix deadlock when setting alarm
Windows alarms are both armed and executed from the interrupt thread.
rte_eal_alarm_set() dispatched alarm-arming code to that thread and
waited for its completion via a spinlock. However, if called from alarm
callback (i.e. from the interrupt thread), this caused a deadlock,
because arming could not be run until its dispatcher exits, but it could
only exit after it finished waiting for arming to complete.

Call arming code directly when running in the interrupt thread.

managing mbuf registrations inside the driver, as properly documented,

There is already a dynamic field for timestamp,

The same field can be used for Rx timestamp filled by drivers.

A new dynamic flag is defined for Rx usage.
A new function wraps the registration of both field and Rx flag.
The type rte_mbuf_timestamp_t is defined for the API users.

After migrating all Rx timestamp usages, it will be possible
to remove the deprecated timestamp field.

d992fa555d trace: fixup CTF event description at registration
CTF event description is currently built by appending all fields in a
single string at trace point registration.
When dumping the metadata, this string is split again and inspected to
fixup reserved keywords and special tokens like "." or "->".

Move this fixup per field at trace point registration time so that there
is no need for inspecting / string parsing when dumping metadata.
Use dynamic allocations to remove an artificial size limit on the CTF
event description manipulations.

1280214212 eal: add intrinsics support check infrastructure
Currently, it is not possible to check support for intrinsics that
are platform-specific, cannot be abstracted in a generic way, or do not
have support on all architectures. The CPUID flags can be used to some
extent, but they are only defined for their platform, while intrinsics
will be available to all code as they are in generic headers.

This patch introduces infrastructure to check support for certain
platform-specific intrinsics, and adds support for checking support for
IA power management-related intrinsics for UMWAIT/UMONITOR and TPAUSE.

cda57d9388 eal: add power management intrinsics
Add two new power management intrinsics, and provide an implementation
in eal/x86 based on UMONITOR/UMWAIT instructions. The instructions
are implemented as raw byte opcodes because there is not yet widespread
compiler support for these instructions.

The power management instructions provide an architecture-specific
function to either wait until a specified TSC timestamp is reached, or
optionally wait until either a TSC timestamp is reached or a memory
location is written to. The monitor function also provides an optional
comparison, to avoid sleeping when the expected write has already
happened, and no more writes are expected.
