net/mlx5: fix Tx when first segment size is too short

First segment size must be at least 18 bytes, packets not respecting this
are silently not sent by the NIC but counted as sent by the PMD.  The only
way to figure out is compiling the PMD in debug mode.

net/qede: prevent crash while changing MTU dynamically

The driver can handle dynamic MTU change without needing the port to be
stopped explicitly by the application. However, there is currently no
check to prevent I/Os from happening on a different thread while the
port is going thru' reset internally. This patch fixes this issue by
assigning RX/TX burst functions to a dummy function and also reconfigure
RX bufsize for each rx queue based on the new MTU value.

net/qede: fix VF RSS configuration

deferring RSS configuration till the queues are created. Even though
this issue is only seen in SR-IOV context, the changes will be made
applicable to PF also to keep the behavior consistent between VF/PF.

net/qede/base: multi-Txq support on same queue-zone for VFs

A step toward having multi-Txq support on same queue-zone for VFs.

This change takes care of:

 - VFs assume a single CID per-queue, where queue X receives CID X.
   Switch to a model similar to that of PF - I.e., Use different CIDs
   for Rx/Tx, and use mapping to acquire/release those. Each VF
   currently will have 32 CIDs available for it [for its possible 16
   Rx & 16 Tx queues].

 - To retain the same interface for PFs/VFs when initializing queues,
   the base driver would have to retain a unique number per-each queue
   that would be communicated in some extended TLV [current TLV
   interface allows the PF to send only the queue-id]. The new TLV isn't
   part of the current change but base driver would now start adding
   such unique keys internally to queue_cids. This would also force
   us to start having alloc/setup/free for L2 [we've refrained from
   doing so until now]
   The limit would be no-more than 64 queues per qzone [This could be
   changed if needed, but hopefully no one needs so many queues]

 - In IOV, Add infrastructure for up to 64 qids per-qzone, although
   at the moment hard-code '0' for Rx and '1' for Tx [Since VF still
   isn't communicating via new TLV which index to associate with a
   given queue in its queue-zone].

L2 handler changes:

This is change to remove the queue-id/qzone difference for Tx queues.

a. VFs queues are no longer determined by the SBs they're using.
Instead, the ecore-client needs to maintain those and choose the values
to be used by VF when initializing it.

b. Eliminate the HW-cid array in the hw-function.
To do that, have all the rx/tx functionality turn into 'handle' base -
when queue would be started the caller would get a (void*) handle,
which it would later use with ecore for configuring various
queue-related stop [update, close].

net/avp: handle interrupt migration

This commit introduces changes required to support VM live-migration.  This
is done by registering and responding to interrupts coming from the host to
signal that the memory is about to be made invalid and replaced with a new
memory zone on the destination compute node.

Enabling and disabling of the interrupts are maintained outside of the
start/stop functions because they must be enabled for the lifetime of the
device.  This is so that host interrupts are serviced and acked even in
cases where the app may have stopped the device.

net/avp: add device start and stop operations

Adds support for device start and stop functions.  This allows an
application to control the administrative state of an AVP device.  Stopping
the device will notify the host application to stop sending packets on that
device's receive queues.
