The condition, "(pf->flags | I40E_FLAG_VMDQ)" will always be true,
regardless of the value of the flags operand, because I40E_FLAG_VMDQ
is 4ULL - meaning at least one bit will always be set in the result.
That will cause log error when VMDq is disabled.
Since the original intent behind the condition is to check if VMDq
is enabled, fix the code by changing "|" to "&".

Depending on HW revision readless communcation between host and device
may be unavailable. In that case prevent PMD from setting up readless
communication mechanism.
"readless" refers to ability to read ENA registers without actually
issuing read request from host (x86). Instead, host programs 2 registers
on the device that triggers a DMA from device to host and reports a
register value. However, this functionality is not going to be available
in all types of devices. The decision if this mode is supported or not,
is taken from revision_id in pci configuration space.

We find that when traffic is light, a small number of packets will have
wrong metadata (e.g. packet type), however this issue will not happen
when traffic is heavy.
The root cause is some fields in fm10k_rx_desc are read at the wrong time,
since the descriptor (being 16-bytes big) is not read as a single atomic
operation. When the input speed is slower than software's capability,
fm10k scalar Rx function accesses descriptors at about the same time
as HW writes them, so the scenario can occur: some fields like pkt_info
in fm10k_rx_desc are read before HW writeback but some fields like DD bit
are read after HW writeback, this will lead to the later packet parsing
function using incorrect value.
This patch fixes this issue by reading and parsing Rx descriptor only after
first checking that the DD bit is set.

Modify the PMD_REGISTER_DRIVER macro, adding a name argument to it. The
addition of a name argument creates a token that can be used for subsequent
macros in the creation of unique symbol names to export additional bits of
information for use by the pmdinfogen tool. For example:
PMD_REGISTER_DRIVER(ena_driver, ena);
registers the ena_driver struct as it always did, and creates a symbol
const char this_pmd_name0[] __attribute__((used)) = "ena";
which pmdinfogen can search for and extract. The subsequent macro
DRIVER_REGISTER_PCI_TABLE(ena, ena_pci_id_map);
creates a symbol const char ena_pci_tbl_export[] __attribute__((used)) =
"ena_pci_id_map";
Which allows pmdinfogen to find the pci table of this driver
Using this pattern, we can export arbitrary bits of information.
pmdinfo uses this information to extract hardware support from an object
file and create a json string to make hardware support info discoverable
later.

Pull in common VNIC code which enables querying for max egress
packet size with newer firmware via a device command. If the
field is non-zero, it is the max egress packet size. If it is
0, the default value (9022) can safely be assumed. The value
for 1300 series VICS using firmware versions >= 3.1.2 for blade
series and >= 2.0.13 for rack series servers is 9208.
Tx buffers can be emitted only if they are less than the max egress
packet size regardless of the MTU setting (the MTU is advisory).
The max egress packet size can used to determine the upper limit
of the MTU since the enic can also receive packets of size greater
than max egress packet size. A max_mtu variable is added with
a value of max egress packet size minus L2 header size.
The default MTU is set via the CIMC/UCSM management interface and
currently allows value up to 9000. If the value is changed, the
host must be reboot. To avoid the reboot and allow MTU values
up to the max capability of the NIC, MTU update capability will
be added with a max value capped by max_mtu.

This patch adds X550a flow control auto negotiation support.
ixgbe_setup_fc_x550a and ixgbe_fc_autoneg_X550a functions are
added to setup and enable flow control. MAC ops function pointer
fc_autoneg was added so that hardware specific fc autoneg functions
can be called from ixgbe_fc_enable_generic.

For X540 onwards it is possible if a system reset occurs at the
right time to leave the SWFW semaphore high. This new function will
attempt to grab and release the semaphore. If the grab times out it
will still release the semaphore placing it in a known good state.
The idea is to call this when you know no one should be holding the
semaphore (i.e. probe time)

This commit brings back Rx scatter and related support by the MTU update
function. The maximum number of segments per packet is not a fixed value
anymore (previously MLX5_PMD_SGE_WR_N, set to 4 by default) as it caused
performance issues when fewer segments were actually needed as well as
limitations on the maximum packet size that could be received with the
default mbuf size (supporting at most 8576 bytes).
These limitations are now lifted as the number of SGEs is derived from the
MTU (which implies MRU) at queue initialization and during MTU update.

The primary purpose of rxq_rehash() function is to stop and restart
reception on a queue after re-posting buffers. This may fail if the array
that temporarily stores existing buffers for reuse cannot be allocated.
Update rxq_rehash() to work on the target queue directly (not through a
template copy) and avoid this allocation.
rxq_alloc_elts() is modified accordingly to take buffers from an existing
queue directly and update their refcount.
Unlike rxq_rehash(), rxq_setup() must work on a temporary structure but
should not allocate new mbufs from the pool while reinitializing an
existing queue. This is achieved by using the refcount-aware
rxq_alloc_elts() before overwriting queue data.

Compared to its previous incarnation, the software limit on the number of
mbuf segments is no more (previously MLX5_PMD_SGE_WR_N, set to 4 by
default) hence no need for linearization code and related buffers that
permanently consumed a non negligible amount of memory to handle oversized
mbufs.
The resulting code is both lighter and faster.
With the addition of this code, older GCC versions (such
as 4.8.5) may complain about 'wqe' variable being uninitialized, so
initialize it preemptively, even though it is not necessary to do so.

Mini (compressed) completion queue entries (CQEs) are returned by the
NIC when PCI back pressure is detected, in which case the first CQE64
contains common packet information followed by a number of CQE8
providing the rest, followed by a matching number of empty CQE64
entries to be used by software for decompression.
Before decompression:
0 1 2 6 7 8
+-------+ +---------+ +-------+ +-------+ +-------+ +-------+
| CQE64 | | CQE64 | | CQE64 | | CQE64 | | CQE64 | | CQE64 |
|-------| |---------| |-------| |-------| |-------| |-------|
| ..... | | cqe8[0] | | | . | | | | | ..... |
| ..... | | cqe8[1] | | | . | | | | | ..... |
| ..... | | ....... | | | . | | | | | ..... |
| ..... | | cqe8[7] | | | | | | | | ..... |
+-------+ +---------+ +-------+ +-------+ +-------+ +-------+
After decompression:
0 1 ... 8
+-------+ +-------+ +-------+
| CQE64 | | CQE64 | | CQE64 |
|-------| |-------| |-------|
| ..... | | ..... | . | ..... |
| ..... | | ..... | . | ..... |
| ..... | | ..... | . | ..... |
| ..... | | ..... | | ..... |
+-------+ +-------+ +-------+
This patch does not perform the entire decompression step as it would be
really expensive, instead the first CQE64 is consumed and an internal
context is maintained to interpret the following CQE8 entries directly.
Intermediate empty CQE64 entries are handed back to HW without further
processing.
