net/mlx5: fix DevX event registration timing

The DevX counter management triggers an asynchronous event to get back
the new counters values from the HW.

The counter management doesn't trigger 2 parallel events for the same
pool, hence, the pool cannot be updated again in the event waiting time.

When the port is stopped, the DevX event mechanism wrongly was
destroyed what remained all the waiting pools in waiting state forever.

As a result, the counters of the stuck pools were never updated again.

Separate the DevX interrupt installation from the dev installation and
remove the DevX interrupt unregistration\registration from the
stop\start operations.

Now, the DevX interrupt should be installed in probe and uninstalled in
close.

net/af_xdp: support unaligned umem chunks

This patch enables the unaligned chunks feature for AF_XDP which allows
chunks to be placed at arbitrary places in the umem, as opposed to them
being required to be aligned to 2k. This allows for DPDK application
mempools to be mapped directly into the umem and in turn enable zero copy
transfer between umem and the PMD.

This patch replaces the zero copy via external mbuf mechanism introduced
in commit e9ff8bb71943 ("net/af_xdp: enable zero copy by external mbuf").
The pmd_zero copy vdev argument is also removed as now the PMD will
auto-detect presence of the unaligned chunks feature and enable it if so
and otherwise fall back to copy mode if not detected.

net/mlx5: fix crash on hash Rx queue handling for drop

When to create hrxq for the drop, it could fail on creating qp and goto
the error handle which will release created ind_table by calling drop
release function, which takes rte_ethdev as the only parameter and uses

net/i40e: support flow director on SSE Rx

This commit adds an implementation to the SSE vector implementation of
RX routine and moves some common defines from a c file to the header
file.

I40e can have 16 and 32 byte descriptors, and the Flow
Director ID data and indication-bit are in different locations
for each size descriptor. The support is implemented in two
separate functions as they require vastly different operations.

The 16B descriptor re-purposes the "filter-status" u32 field
to indicate FDIR ID when the FLM bit is set. No extra loads
are required, however we do have to store to mbuf->fdir.hi,
which is not stored to in the RX path before this patch.

The 32B descriptor requires loading the 2nd 16 bytes of each
descriptor, to get the FLEXBH_STAT and FD Filter ID from
qword3. The resulting data must also be stored to mbuf->fdir.hi,

net/axgbe: fix double unlock

One issue caught by Coverity 340835
*unlock: axgbe_phy_set_mode unlocks pdata->phy_mutex
*double_unlock: axgbe_phy_sfp_detect unlocks pdata->phy_mutex
while it is unlocked.

In axgbe_phy_sfp_detect()/axgbe_phy_set_redrv_mode(),
axgbe_phy_get_comm_ownership() and axgbe_phy_put_comm_ownership()
are invoked subsequently.

Currently in axgbe_phy_get_comm_ownership(), during one of the case
'phy_data->comm_owned' is not protected and before returning 0, lock is
not called and unlock is called in axgbe_phy_put_comm_ownership()
directly which is incorrect.

Ideally, the variable 'phy_data->comm_owned' needs to be protected.
During success scenario, lock is called in
axgbe_phy_get_comm_ownership() followed by unlock in
axgbe_phy_put_comm_ownership().  In failure case, unlock is invoked in
axgbe_phy_get_comm_ownership() itself appropriately.

The fix is to protect 'phy_data->comm_owned' in the identified case
ensuring locks/unlocks properly exist.

vhost: improve performance by supporting large buffer

The rte_vhost_dequeue_burst supports two ways of dequeuing data.
If the data fits into a buffer, then all data is copied and a
single linear buffer is returned. Otherwise it allocates
additional mbufs and chains them together to return a multiple
segments mbuf.

While that covers most use cases, it forces applications that
need to work with larger data sizes to support multiple segments
mbufs. The non-linear characteristic brings complexity and
performance implications to the application.

To resolve the issue, add support to attach external buffer
to a pktmbuf and let the host provide during registration if
attaching an external buffer to pktmbuf is supported and if
only linear buffer are supported.

net/ice/base: initialize structures to zero

Some functions create ice_pkg_enum structure, but it seems it's possible
some of the members are used un-initialized.  So we'll initialize all
instantiations of this structure within ice_flex_pipe.c

The patch also fix header comment mismatch issue for
ice_init_prof_result_bm

net/ice/base: remove dead error condition

NULL.  Remove the check-for-NULL lines since it's dead code anyway.

net/ice/base: improve flow director masking

Currently, 3-tuple FD matching is implemented using masking. However,
this is using up twenty-four of the thirty-two FD masks available. This
patch uses the swap register more efficiently to implement the 3-tuple
matches, which saves all FD masks for other uses.

Added IPV6 versions of DSCP, TTL and Protocol fields for flow director
use.

net/ice/base: update flow packet type bitmaps

In the flow API, the outer first ptype bitmaps contained many
references to inner ptypes. Because of PTG assignments, these were
causing issues when programming rules on the inner ptypes.
For example, in RSS when programming the outer IPV6 hash fields,
it also programmed several inner IPV4 PTGs with the same extraction.

There were several ptypes that have been removed, thus this patch
removes those bits from the type bitmaps.
