[PATCH 1/2] bna: Remove Unnecessary CNA Check

[Rasesh Mody]

Change details:
 - ioc->cna is always set to 1 for eth functions, remove the check that
   asserts IOC is in CNA mode in bfa_ioc_firmware_lock() and
   bfa_ioc_firmware_unlock() in bfa_ioc_ct.c.

[PATCH 2/2] bna: HW Interface Init Update

[Rasesh Mody]

Change details:
 - Split the hw interface into common and asic specific to support new asic
   in the future.
 - Fix bfa_ioc_ct_isr_mode_set() to also include the case that we are already
   in the desired msix mode.

So are these bug fixes or cleanups/features?  You don't say where
you intend these changes to go.

Can you please put these into net-next tree? These patches remove unnecessary code and updates h/w initialize code.

We'll submit the features/cleanups patches in subsequent submissions against net-next.

Thanks,
