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 72ef3a88 ("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.

Newer firmware will return the ring group resource when we call
hwrm_func_qcaps().  To be compatible with older firmware, use the
number of tx rings as the number of ring groups if the older firmware
returns 0.  When determining how many rx rings we can support, take
the ring group resource in account as well in _bnxt_get_max_rings().
Divide and assign the ring groups to VFs.

We need to keep track of all resources, such as rx rings, tx rings,
cmpl rings, rss contexts, stats contexts, vnics, after we have
divided them for the VFs.  Otherwise, subsequent ring changes on
the PF may not work correctly.

We adjust all max resources in struct bnxt_pf_info after they have been
assigned to the VFs.  There is no need to keep the separate
max_pf_tx_rings and max_pf_rx_rings.

When SR-IOV is disabled, we call bnxt_hwrm_func_qcaps() to restore the
max resources for the PF.

The hardware resources required to enable NTUPLE varies depending on
how many rx channels are configured.  We need to make sure we have the
resources before we enable NTUPLE.  Add bnxt_rfs_capable() to do the
checking.

In addition, we need to do the same checking in ndo_fix_features().  As
the rx channels are changed using ethtool -L, we call
netdev_update_features() to make the necessary adjustment for NTUPLE.

Calling netdev_update_features() in netif_running() state but before
calling bnxt_open_nic() would be a problem.  To make this work,
bnxt_set_features() has to be modified to test for BNXT_STATE_OPEN for
the true hardware state instead of checking netif_running().
