ixgbevf: Use mac_ops instead of trying to identify NIC type

Orabug: 24568240

This change makes it so that we can just use function pointers instead of
having to identify if a given VF is running on a Linux or Windows PF.  By
doing this we can avoid having to pull too much information out of the
lower layers and can instead just make use of the mac_ops pointers since
they should differ between the two types of VFs anyway.

Previously the PF driver would only set VLAN spoof checking if
the VF had created VLANs. This was done by setting and checking
a counter (vlan_count) whenever a VLAN was created by the VF.
However it is possible for the vlan_count to be !=0 while there are
no VLANs assigned to the VF due to the count incrementing every
time a VLAN 0 is added on ifdown/up, which resulted in VLAN spoofing
always being set for those VFs.

This patch cleans up the logic by unconditionally setting VLAN based on
how the VF is configured (via ip link set ethX vf Y spoofchk on/off).
This change also resolves an issue where the VLAN spoofing can remain
set even after being disabled by the user due to the driver enabling
VLAN spoof checking every time a VLAN is added to the VF, but would
only allow changes in the setting if vlan_count != 0.

Also default_vf_vlan_id and vlans_enabled were removed from the

we need to create an interface to allow the RDMA driver to share resources

1. Create a new bnxt_en_dev struct which will be returned by
bnxt_ulp_probe() upon success.  After that, all calls from the RDMA driver
to bnxt_en will pass a pointer to this struct.

2. This struct contains additional function pointers to register, request
msix, send fw messages, register for async events.

3. If the RDMA driver wants to enable RDMA on the function, it needs to
call the function pointer bnxt_register_device().  A ulp_ops structure
is passed for RCU protected upcalls from bnxt_en to the RDMA driver.

4. The RDMA driver can call firmware APIs using the bnxt_send_fw_msg()
function pointer.

5. 1 stats context is reserved when the RDMA driver registers.  MSIX
and completion rings are reserved when the RDMA driver calls
bnxt_request_msix() function pointer.

6. When the RDMA driver calls bnxt_unregister_device(), all RDMA resources
will be cleaned up.

scsi: smartpqi: raid bypass lba calculation fix

Orabug: 25144431

In the ioaccel path, the calculation of the starting LBA for
READ(6)/WRITE(6) SCSI commands does not take into account the most
significant 5 bits of the LBA: it only uses the least significant 16
bits of the starting LBA.
