Hariprasad Shenai e2ac962895 cxgb4: Cleanup macros so they follow the same style and look consistent, part 2
Various patches have ended up changing the style of the symbolic macros/register
defines to different style.

As a result, the current kernel.org files are a mix of different macro styles.
Since this macro/register defines is used by different drivers a
few patch series have ended up adding duplicate macro/register define entries
with different styles. This makes these register define/macro files a complete
mess and we want to make them clean and consistent. This patch cleans up a part
of it.

Add 40G support for cxgb4vf driver. ethtool speed values are just numbers of

use integer constants directly for all speeds.

Use is_x_10g_port()("is 10Gb/s or higher") in cfg_queues() instead of
is_10g_port() ("is exactly 10Gb/s"). Else we will end up using a single

Alexander Gordeev f6f273bfe1 cxgb4vf: Remove superfluous call to pci_disable_msix()
There is no need to call pci_disable_msix() in case
the previous call to pci_enable_msix() failed

stephen hemminger de5b867741 cxgb4: make functions static and remove dead code
Cleanup by making local functions static.

The code to load config file is unreachable in net-next, probably came
from some out of tree driver.

Jingoo Han cefa63b598 net: cxgb4vf: remove unnecessary pci_set_drvdata()
The driver core clears the driver data to NULL after device_release
or on probe failure. Thus, it is not needed to manually clear the
device driver data to NULL.

Vipul Pandya 94dace1014 cxgb4vf: Support CPL_SGE_EGR_UPDATEs encapsulated in a CPL_FW4_MSG
Newer firmware can post CPL_SGE_EGR_UPDATE message encapsulated in a
CPL_FW4_MSG as follows

flit0 rss_header (if DropRSS == 0 in IQ context)
flit1 CPL_FW4_MSG cpl
flit2 rss_header w/opcode CPL_SGE_EGR_UPDATE
flit3 CPL_SGE_EGR_UPDATE cpl

So FW4_MSG CPLs with a newly created type of FW_TYPE_RSSCPL have the
CPL_SGE_EGR_UPDATE CPL message in flit 2 of the FW4_MSG. Firmware can still
post regular CPL_SGE_EGR_UPDATE messages, so the drivers need to handle
both.

This patch also writes a new parameter to firmware requesting encapsulated
EGR_UPDATE. This allows firmware with this support to not break older drivers.
