Optimize cache-line access in ecore_chain -
re-arrange fields so that fields that are needed for fastpath
[mostly produce/consume and their derivatives] are in the first cache
line, and the rest are in the second.
This is true for both PBL and NEXT_PTR kind of chains.
Advancing a page in a SINGLE_PAGE chain would still require the 2nd
cacheline as well, but afaik only SPQ uses it and so it isn't
considered as 'fastpath'.

L2 handler changes:
This is change to remove the queue-id/qzone difference for Tx queues.
It does that by mainly doing:
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].

Allow only trusted VFs to be promisc/multi-promisc. The reasonable
thing is to use the 'trusted' node instead of simply allowing VFs to
become promiscuous.

This change is in preparation to work with new FW 8.18.9.0.
Rename the defines to use E4_ and structs to use e4_. This renaming
is to add support for future chipsets.

When a server doesn't support ARI, VF offsets begin at a much higher
number. As a result, ecore miscalculates the first_vf_in_pf and
initialization fails since base driver incorrectly learns there are
no SBs for its VF [as its VFs are out of range].

VFs are seeing the number of MACs available to them as '0',

prevent that.

There are some constellations where Due to lack of resource allocation
in MFW, There would be an insufficient number of L2 queues for all the
VFs.
This introduces a new feature ECORE_VF_L2_QUE which correctly numbers
the number of VF queues. Notice it might be larger than the actual
number of VFs in configuration space, in which case its the ecore
client responsibility not to try activating that many.
As part of the fix, also correct the nubmering of the VF queues. As
their numbering is dependent on the SBs of the PF, which might only be
partially used by L2 [as half would be assigned for RDMA which doesn't
require L2 queues], we make the numbering consecutive with that of the
L2 queues only.
