72aca4bfce cxgb4: Add support to recognize 40G links
Also, create a new Common Code interface to translate Firmware Port Technology
Type values (enum fw_port_type) to string descriptions.  This will allow us
to maintain the description translation table in one place rather than in
every driver.

Based on original work by Scott Bardone and Casey Leedom <leedom@chelsio.com>

b4b39061da wil6210: Use pci_enable_msi_range() instead of pci_enable_msi_block()
As result of deprecation of MSI-X/MSI enablement functions
pci_enable_msix() and pci_enable_msi_block() all drivers
using these two interfaces need to be updated to use the
new pci_enable_msi_range() and pci_enable_msix_range()
interfaces.

b60b869d5f vmxnet3: Fix MSI-X/MSI enablement code
This update cleans up the MSI-X/MSI enablement code, fixes
vmxnet3_acquire_msix_vectors() invalid return values and
enables a dead code in case VMXNET3_LINUX_MIN_MSIX_VECT
MSI-X vectors were allocated.

7cca336ae1 gianfar: Remove clean_rx_ring race from gfar_ethtool
gfar_clean_rx_ring() was designed to be called from napi
(rx softirq) context to do the Rx processing. Calling it
from a process context like this is a bug as it will
clearly race with the napi Rx processing.

There's also no point in initializing num_txbdfree since
startup_gfar() already does that, when bringing the device
up again (after reset). Changing num_txbdfree "on-the-fly"
like this is also subject to race conditions.  num_txbdfree
is handled by the Tx processing path and the device reset
procedure.  Also, don't assume that num_rx_queues is always
equal to num_tx_queues.

c10650b661 gianfar: Add missing graceful reset steps and fixes
gfar_halt() and gfar_start() are responsible for stopping
and starting the DMA and the Rx/Tx hw rings. They implement
the support for the "graceful Rx/Tx stop/start" hw procedure,
and also disable/enable eTSEC's hw interrupts in the process.

The GRS/GTS procedure requires however to have the RQUEUE/TQUEUE
registers cleared first and to wait for a period of time for the
current frame to pass through the interface (around ~10ms for a
jumbo frame). Only then may the GTS and GRS bits from DMACTRL be
set to shut down the DMA, and finally the Tx_EN and Rx_EN bits in
MACCFG1 may be cleared to disable the Tx/Rx blocks.

The same register programming order applies to start the Rx/Tx:
enabling the RQUEUE/TQUEUE *before* clearing the GRS/GTS bits.

This is a HW recommendation in order to avoid a possible
controller "lock up" during graceful reset.

Cleanup the gfar_halt()/start() prototypes, to take priv instead
of ndev as their purpose is to operate on HW. Enabling the
RQUEUE/TQUEUE in the hw_init() is not needed anymore since
that's the job of gfar_start().

Throughout the code there are places where the controller's

the interrupts is to clear the ievent first then the imask
register (not the other way around).
Use the gfar_ints_enable/disable() helpers to make these
operations consistent.

Removing the sysfs stubs for the Tx FIFOCFG and ATTRELI

be configured after a MAC reset, with the controller stopped

measures are useless and only add unecessary code).

Changing these registers is discouraged. Only the default values
will be used instead.

Moreover, the stashing (ATTRELI) configuration options were
effectively disabled (didn't get to the hw anyway if changed)
because the stashing device_flags (HAS_BD_STASHING|HAS_BUF_STASHING)

208627883e gianfar: Cleanup/Fix gfar_probe and the hw init code
Factor out gfar_hw_init() to contain all the controller hw
initialization steps for a better control of register writes,
and to significantly simplify the tangled code from gfar_probe().
This results in code size and stack usage reduction (besides
code readability).

Fix memory leak on device removal, by freeing the rx_/tx_queue
structures.

Replace custom bit swapping function with a library one (bitrev8).

Move allocation of rx_/tx_queue struct arrays before the group
structure init, because in order to assign Rx/Tx queues
to groups we need to have the queues first.  This also allows
earlier bail out of gfar_probe(), in case the memory allocation
fails.

The flow control checks for maccfg1 were removed from gfar_probe(),
since flow control is disabled at probe time (priv->rx_/tx_pause_en
are 0). Redundant initializations (by 0) also removed.

described workaround seems to not fully work either; my RF212 chips will
not correctly receive any frames unless they are taken from RX mode to
TRX_OFF and back to RX mode, effectively forcing a up-down-up-cycle.
Going to TRX_OFF and to RX without intermediate state changes at least
once fixes this.

eb85569fe2 usbnet: remove generic hard_header_len check
This patch removes a generic hard_header_len check from the usbnet
module that is causing dropped packages under certain circumstances
for devices that send rx packets that cross urb boundaries.

One example is the AX88772B which occasionally send rx packets that
cross urb boundaries where the remaining partial packet is sent with
no hardware header. When the buffer with a partial packet is of less
number of octets than the value of hard_header_len the buffer is
discarded by the usbnet module.

With AX88772B this can be reproduced by using ping with a packet
size between 1965-1976.

The bug has been reported here:

https://bugzilla.kernel.org/show_bug.cgi?id=29082

This patch introduces the following changes:
- Removes the generic hard_header_len check in the rx_complete
  function in the usbnet module.
- Introduces a ETH_HLEN check for skbs that are not cloned from
  within a rx_fixup callback.
- For safety a hard_header_len check is added to each rx_fixup
  callback function that could be affected by this change.
  These extra checks could possibly be removed by someone
  who has the hardware to test.
- Removes a call to dev_kfree_skb_any() and instead utilizes the
  dev->done list to queue skbs for cleanup.

The changes place full responsibility on the rx_fixup callback
functions that clone skbs to only pass valid skbs to the
usbnet_skb_return function.

handler can then be replaced on other call-sites with different
queue selection methods (e.g. in packet sockets, pktgen etc).

This also has the nice side-effect that __netdev_pick_tx() is
then only invoked from netdev_pick_tx() and export of that
function to modules can be undone.

The struct driver_info ax88178_info is assigned the function
asix_rx_fixup_common as it's rx_fixup callback. This means that
FLAG_MULTI_PACKET must be set as this function is cloning the

This patch adds support for configuring the port multiplexer hardware
which resides in front of the GENET Ethernet MAC controller. This allows
us to support:

- internal PHYs (using drivers/net/phy/bcm7xxx.c)
- MoCA PHYs which are an entirely separate hardware block not covered
  here
- external PHYs and switches

Note that MoCA and switches are currently supported using the emulated
"fixed PHY" driver.

This patch adds support for the Broadcom BCM7xxx Set Top Box SoCs
internal PHYs. This driver supports the following generation of SoCs:

- BCM7366, BCM7439, BCM7445 (28nm process)
- all 40nm and 65nm (older MIPS-based SoCs)

The PHYs on these SoCs require a bunch of workarounds to operate
correctly, both during configuration time and at suspend/resume time,
the driver handles that for us.

602b109942 net:phy:dp83640: Move all HW initialization to dp83640_config_init
phy_init_hw not does a full PHY reset after the driver probe has
finished, so any hw initialization done in the probe will be lost.
Part of the timestamping functionality of the dp83640 is set up in the
probe and with that lost, enabling timestamping will cause a PHY
lockup, requiring a hard reset / power cycle to recover.

This patch moves all the HW initialization in dp83640_probe to
dp83640_config_init.

Reason is buggy end condition in for loop in cpsw_set_promiscious()

for (i = 0; i <= priv->data.slaves; i++)

should be

for (i = 0; i < priv->data.slaves; i++)

f93f160b5a be2net: refactor multi-channel config code for Skyhawk-R chip
Currently multi-channel configuration is read via the QUERY_FW_CONFIG cmd.
This method has been deprecated by the Skyhawk-R FW. Instead,
GET_PROFILE_CONFIG::port-desc must be used to query this configuration.

This patch also:
a) introduces a few macros to identify certain categories of multi-channel
configs
2) re-factors the be_cmd_set_profile_config() code to be able to read any kind
of desc (and not just the nic-desc.)
