dev->nr_luns reports the total number of luns available in a device
while dev->luns_per_chnl is the number of luns per channel.
When multiple channels are available, the offset is calculated from a
channel and lun id into a linear array. As it multiplies with
the total number of luns, we go out of bound when channel id > 0 and
causes the kernel to panic when we read a protected kernel memory area.

Recently Dough Ledford reported a deadlock happening
between ocrdma-load sequence and NetworkManager service
issueing "open" on be2net interface.
The deadlock happens when any be2net hook (e.g. open/close) is called
in parallel to insmod ocrdma.ko.
A. be2net is sending administrative open/close event to ocrdma holding
device_list_mutex. It does this from ndo_open/ndo_stop hooks of be2net.
So sequence of locks is rtnl_lock---> device_list lock
B. When new ocrdma roce device gets registered, infiniband stack now
takes rtnl_lock in ib_register_device() in GID initialization routines.
So sequence of locks in this path is device_list lock ---> rtnl_lock.
This improper locking sequence causes deadlock.
In order to resolve the above deadlock condition, ocrdma intorduced a
patch to stop listening to administrative open/close events generated from
be2net driver. It now depends on link-state-change async-event generated from
CNA. This change leaves behind dead code which used to generate administrative
open/close events. This patch cleans-up all that dead code from be2net.

With this patch we stop using administrative open and close events
injected by be2net driver. These events were used to dispatch PORT_ACTIVE
and PORT_ERROR events to the IB-stack. This patch implements a logic
to receive async-link-events generated from CNA whenever link-state-change
is detected. Now on, these async-events will be used to dispatch
PORT_ACTIVE and PORT_ERROR events to IB-stack.
Depending on async-events from CNA removes the need to hold device-list-mutex
and thus breaks the busy-wait scenario.

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().
