This patch adds support for ethtool's --get-dump option in be2net,
to retrieve FW dump. In the past when this option was not yet available,
this feature was supported via the --register-dump option as a workaround.
This patch removes support for FW-dump via --register-dump option as it is
now available via --get-dump option. Even though the
"ethtool --register-dump" cmd which used to work earlier, will now fail
with ENOTSUPP error, we feel it is not an issue as this is used only
for diagnostics purpose.

Commit 72ef3a88fa ("be2net: set pci_func_num while issuing
GET_PROFILE_CONFIG cmd") passed a specific pf_num while issuing a
GET_PROFILE_CONFIG cmd as FW returns descriptors for all functions when
pf_num is zero. But, when pf_num is set to a non-zero value, FW does not
return the Port resource descriptor.
This patch fixes this by setting pf_num to 0 while issuing the query cmd
and adds code to pick the correct NIC resource descriptor from the list of
descriptors returned by FW.

The VF link state setting transition from "disable" to "auto" does not work
due to a bug in SET_LOGICAL_LINK_CONFIG_V1 cmd in FW. This issue could not
be fixed in FW due to some backward compatibility issues it causes with
some released drivers. The issue has been fixed by introducing a new
version (v2) of the cmd from 10.6 FW onwards. In v2, to set the VF link
state to auto, both PLINK_ENABLE and PLINK_TRACK bits have to be set to 1.
The VF link state setting feature now works on Lancer chips too from
FW ver 10.6.315.0 onwards.

OS2BMC feature will allow the server to communicate with the on-board
BMC/idrac (Baseboard Management Controller) over the LOM via
standard Ethernet.
When OS2BMC feature is enabled, the LOM will filter traffic coming
from the host. If the destination MAC address matches the iDRAC MAC
address, it will forward the packet to the NC-SI side band interface
for iDRAC processing. Otherwise, it would send it out on the wire to
the external network. Broadcast and multicast packets are sent on the
side-band NC-SI channel and on the wire as well. Some of the packet
filters are not supported in the NIC and hence driver will identify
such packets and will hint the NIC to send those packets to the BMC.
This is done by duplicating packets on the management ring. Packets
are sent to the management ring, by setting mgmt bit in the wrb header.
The NIC will forward the packets on the management ring to the BMC
through the side-band NC-SI channel.

This patch adds support for spoofchk configuration for VFs.
When it is enabled, "spoof checking" is done for both MAC-address and VLAN.
For each VF, the HW ensures that the source MAC address (or vlan) of
every outgoing packet exists in the MAC-list (or vlan-list) configured
for RX filtering for that VF. If not, the packet is dropped and an error
is reported to the driver in the TX completion; this is reflected in the
"tx_spoof_check_err" ethtool counter.
This feature is supported in Skyhawk FW version 10.6.31.0 and above.

While sending FW update cmds to the FW, the driver specifies the "type"
of each component that needs to be flashed. The FW then picks the offset
in the flash area at which the componnet is to be flashed. This doesn't work
when new components that the current FW doesn't recognize, need to be
flashed. Recent FWs (10.2 and above) support a scheme of FW-update wherein
the "offset" of the component in the flash area can be specified instead
of the "type". This patch uses the "offset" based FW-update mechanism and
only when it fails, it fallsback to the old "type" based update.

The driver (on PF or VF) needs to detect if the function is in qnq mode for
a HW hack in be_rx_compl_get() to work.
The driver queries this information using the GET_PROFILE_CONFIG cmd
(since the commit below can caused this regression.) But this cmd is not
available on VFs and so the VFs fail to detect qnq mode. This causes
vlan traffic to not work.
The fix is to use the the adapter->function_mode value queried via
QUERY_FIRMWARE_CONFIG cmd on both PFs and VFs to detect the qnq mode.
Also QNQ_MODE was incorrectly named FLEX10_MODE; correcting that too as the
fix reads much better with the name change.

Now, embedd both statuses in the return value and let the caller routine access
the value of interest using base_status() and addl_status() macros.
b) Rename variables accordingly (base/addl) to avoid confusion while error
checking.
b) Some of the errors returned by FW are harmless and so an error msg is not
logged for such errors. Capture this logic in a separate routine to make the
