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.

1. Use local variable pf for repeated access to this pointer.
2. The 2nd argument num_vfs was unnecessarily declared as pointer to int.
This function doesn't change num_vfs so change the argument to int.

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().

During remove_one, the driver should issue hwrm_func_drv_unrgtr
command to inform firmware that this function has been unloaded.
This is to let firmware keep track of driver present/absent state
when driver is gracefully unloaded. A keep alive timer is needed
later to keep track of driver state during abnormal shutdown.

This is a new device driver for a high performance SR-IOV assisted virtual
network for IBM System p and IBM System i systems. The SR-IOV VF will be
attached to the VIOS partition and mapped to the Linux client via the
hypervisor's VNIC protocol that this driver implements.
This driver is able to perform basic tx and rx, new features
and improvements will be added as they are being developed and tested.

The 6320 family of switch chips has a second bank for statistics, but
is missing three statistics in the port registers. Generalise and
extend the code:
* adding a field to the statistics table indicating the bank/register
set where each statistics is.
* add a function indicating if an individual statistics
is available on this device
* calculate at run time the sset_count.
* return strings based on the available statistics of the device
* return statistics based on the available statistics of the device
* Add support for reading from the second bank.

For unprivileged functions operations can be authorised by an admin
function. Extra steps are introduced to the MCDI protocol in this
situation - the initial response from the MCDI tells us that the
operation has been deferred, and we must retry when told. We then
receive an event telling us to retry.
Note that this provides only the functionality for the unprivileged
functions, not the handling of the administrative side.
