Set mc-promisc (multicast promiscuous) mode on an interface, only if it is
*not already* in that mode.
Also removed logs that report interface being set to multicast
promiscous mode. In an earlier comment on the netdev list such log messages
were deemed unnecessary as this behaviour is common across most of the
ethernet drivers.

Yes, can be done. But, what is wrong with clearing the flag after the check ?

More code, and not very justified, IMHO.

Skyhawk-R FW supports TX-rate setting only as a % value of the link
speed, set via the SET_PROFILE_CONFIG cmd.
This patch makes the necessary changes to the FW cmd descriptors to support
the above change and also introduces checks in be_set_vf_tx_rate() to allow
only discrete values (that map to % of the link-speed).

Certain new flash regions have been added to Skyhawk-R FW image. The newer
FW images specify op_types for each region. A region is flashed only
when it's CRC doesn't match that of the region on the HW flash. While
upgrading to a new FW image the driver is expected to tolerate certain
errors.
This patch re-factors code under be_flash() to support the above scheme.

From: Sathya Perla @ 2014-05-30 13:36 UTC (permalink / raw)
To: netdev
From: Kalesh AP <kalesh.purayil@emulex.com>
This patch improves MCCQ error status handling in the following ways:
a) A MCC cmd completion returns a base-status and an addl-status.
So far, the routine be_mcc_compl_process() returned only the "status" value.
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
code more readable.

For some FW cmds, the caller just issues the cmd and doesn't wait for a
response. The response handling is done in the MCCQ compl processing context
only. Move this code into a separate routine to make be_mcc_compl_process()
more manageable.

To: netdev
The MCC async event processing code has 2 issues:
a) because of long struct names the code indentation is badly broken
b) description and definitions of how an MCC completion is interpreted as
an async event are confusing (for e.g. the last word of an MCC event is
named "code", while "code" is just a sub-field of the last word.)
This patch fixes the structure definitions, comments and re-factors code
as needed.
