No need for probe messages when a TxQ is too full for a post to be done.
Existing drivers check if there is room in the queue before posting
descriptors, even though efx_tx_qdesc_post() does the check itself.
The new SFN Windows driver doesn't perform the check before calling
efx_tx_qdesc_post(), but that means these probes can get frequently
printed out. It's normal driver behaviour so there's no need to print
an error.

'stats_reset()' callback was missing because the device backend doesn't
support it.
This commit adds a workaround to this and implements the callback by
taking a snapshot of the stats (SNAPSHOT) each time 'stats_reset()'
is called. When getting stats with 'stats_get()', hw stats which
always increase reduce SNAPSHOT stats.
That's how we get the "real" stats since the last 'stats_reset()'.

The MAC addresses are generated in a similar manner as in the TAP PMD,
where the address is based on the number of PCAP ports created.
This is useful for the purposes of debugging DPDK applications using
PCAP devices instead of real devices where multiple devices should still
have unique MAC addresses. This method was chosen over randomly
assigning MAC addresses to make the creation of pcaps, specifically
matching the destination ethernet address field to an interface, easier.

When trust mode is set to ON, VF can change it's MAC address
inspite PF has set a forced MAC for that VF from HV.
Earlier similar functionality is provided by module parameter
"allow_vf_mac_change_mode" of qed.
This change makes few changes in behavior of VF shadow config -
- Let driver track the VF mac in shadow config as long as trust
mode is OFF.
- Once trust mode is ON, we should not care about MACs in shadow
config (because we never intend to fall back because of lack of restore
implementation).
- Delete existing shadow MAC (this helps when trust mode is turned OFF,
and VF tries to add new MAC – it won’t fail that time since we have
a clean slate).
- Skip addition and deletion of MACs in shadow configs.

For IA, the AVX2 vector path is only recommended to be used on later
platforms (identified by AVX512 support, like SKL etc.) This is because
performance benchmark shows downgrade when running AVX2 vector path on
early platform (BDW/HSW) in some cases. But we still observe perf gain
with some real work loading.
So this patch introduced the new devarg use-latest-supported-vec to
force the driver always selecting the latest supported vec path. Then
apps are able to take AVX2 path on early platforms. And this logic can
be re-used if we will have AVX512 vec path in future.
This patch only affects IA platforms. The selected vec path would be
like the following:
Without devarg/devarg = 0:
Machine vPMD
AVX512F AVX2
AVX2 SSE4.2
SSE4.2 SSE4.2
<SSE4.2 Not Supported
With devarg = 1

AVX2 AVX2
SSE4.2 SSE4.2
<SSE4.2 Not Supported

For the exception vswitch path some tests like transmit

For the VF path, the code is slightly shorter but has no

* the exception packet uses less CPU
* much smaller code size
* no locking required on VF transmit/receive path
* no legacy Linux network device to get mangled by userspace
* much simpler (1K vs 9K) LOC

LLDP with peer, and returns SUCCESS.
This results in the harmless, but annoying, diagnostic:
default dcb config fails. err = -53, aq_err = 1.
So, if possible (older firmwares cannot safely stop LLDP), stop the
LLDP daemon when we are in software mod before we attempt to call
i40e_set_dcb_config.

This patch adds alarm handler, and then i40e
PF will use alarm handler instead of interrupt
handler when device is started and Rx interrupt
mode is disabled. This way will save CPU cycles
during receiving packets.

This patch checks negotiated features to see if necessary to offload
before set the tap device offload capabilities. It also checks if kernel
support the TUNSETOFFLOAD operation.

Rxq cq_ci was 16 bits while hardware is expecting to wrap
around 24 bits, this caused interrupt failure after burst of packets.
