net/qede/base: limit number of non ethernet queues to 64
Limit the number of non ethernet queues to 64, allowing a max queues to
status block ratio of 2:1 in case of storage target. Theoretically a
non-target storage PF can have 128 queues and SBs.
This change is to support 64 entries for a target iSCSI/FCoE PF and 128
for a non-target.
Add support for the following OneView APIs:
- ecore_mcp_ov_update_mtu() - Send MTU value to the management FW.
- ecore_mcp_ov_update_mac() - Send MAC address to the management FW.
- ecore_mcp_ov_update_eswitch() - Send eswitch_mode to management FW
after the firmware load.
This fix adds a ecore_mcp_update_stag() handler to handle the STAG update
events from management FW and program the STAG value.
It also clears the stag config on PF, when management FW invalidates
the stag value.

net/i40e: add option to use latest vector path
For IA, the AVX2 vector path is only recommended to be used on later

performance benchmark shows downgrade when running AVX2 vector path on

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.

Both will force reading the source buffer past the requested size
