The driver currently always sets the PBLx8/PBLx4 bit, which means that
the pbl values configured via the pbl/txpbl/rxpbl DT properties are
always multiplied by 8/4 in the hardware.
In order to allow the DT to configure lower pbl values, while at the
same time not changing behavior of any existing device trees using the
pbl/txpbl/rxpbl settings, add a property to disable the multiplication
of the pbl by 8/4 in the hardware.

GMAC and newer supports independent programmable burst lengths for
DMA tx/rx. Add new optional devicetree properties representing this.
To be backwards compatible, snps,pbl will still be valid, but
snps,txpbl/snps,rxpbl will override the value in snps,pbl if set.
If the IP is synthesized to use the AXI interface, there is a register
and a matching DT property inside the optional stmmac-axi-config DT node
for controlling burst lengths, named snps,blen.
However, using this register, it is not possible to control tx and rx
independently. Also, this register is not available if the IP was
synthesized with, e.g., the AHB interface.

commit 64c3b252e9fc ("net: stmmac: fixed the pbl setting with DT")
changed the parsing of the DT binding.
Before 64c3b252e9fc, snps,fixed-burst and snps,mixed-burst were parsed
regardless if the property snps,pbl existed or not.
After the commit, fixed burst and mixed burst are only parsed if
snps,pbl exists. Now when snps,aal has been added, it too is only
parsed if snps,pbl exists.
Since the DT binding does not specify that fixed burst, mixed burst
or aal depend on snps,pbl being specified, undo changes introduced
by 64c3b252e9fc.
The issue commit 64c3b252e9fc ("net: stmmac: fixed the pbl setting with
DT") tries to address is solved in another way:
The databook specifies that all values other than
1, 2, 4, 8, 16, or 32 results in undefined behavior,
so snps,pbl = <0> is invalid.
If pbl is 0 after parsing, set pbl to DEFAULT_DMA_PBL.
This handles the case where the property is omitted, and also handles
the case where the property is specified without any data.

All drivers except pci glue layer calls stmmac_probe_config_dt.
stmmac_probe_config_dt does a kzalloc dma_cfg.
pci glue layer does kzalloc dma_cfg explicitly, so all current
drivers does a kzalloc dma_cfg.

we can assume that the DMA configuration always exists.

devicetree binding for stmmac states:
- compatible: Should be "snps,dwmac-<ip_version>", "snps,dwmac"
For backwards compatibility: "st,spear600-gmac" is also supported.
Previously, when specifying "snps,dwmac-4.10a", "snps,dwmac" as your
compatible string, plat_stmmacenet_data would have both has_gmac and
has_gmac4 set.
This would lead to stmmac_hw_init calling dwmac1000_setup rather than
dwmac4_setup, resulting in a non-functional driver.
This happened since the check for has_gmac is done before the check for
has_gmac4. However, the order should not matter, so it does not make sense
to have both set.
If something is valid for both, you should do as the stmmac_interrupt does:
if (priv->plat->has_gmac || priv->plat->has_gmac4) ...
The places where it was obvious that the author actually meant
if (has_gmac || has_gmac4) rather than if (has_gmac) has been updated.

devicetree binding for stmmac states:
- compatible: Should be "snps,dwmac-<ip_version>", "snps,dwmac"
For backwards compatibility: "st,spear600-gmac" is also supported.
Since dwmac-generic.c calls stmmac_probe_config_dt explicitly,
another alternative would have been to remove all compatible strings
other than "snps,dwmac" and "st,spear600-gmac" from dwmac-generic.c.
However, that would probably do more good than harm, since when trying
to figure out what hardware a certain driver supports, you usually look
at the compatible strings in the struct of_device_id, and not in some
function defined in a completely different file.
No functional change intended.

40GbE Intel Wired LAN Driver Updates 2016-12-07
This series contains updates to i40e and i40evf only.
Filip modifies the i40e to log link speed change and when the link is
brought up and down.
Mitch replaces i40e_txd_use_count() with a new function which is slightly
faster and better documented so the dim witted can better follow the
code. Fixes the locking of the service task so that it is actually
done in the service task and not in the scheduling function which calls
the service task.
Jacob, being the busy little beaver he is, provides most of the changes
starting restores a workaround that is still needed in some configurations,
specifically the Ethernet Controller XL710 for 40GbE QSFP+. Removes
duplicate code and simplifies the i40e_vsi_add_vlan() and
i40e_vsi_kill_vlan() functions. Removes detection of PTP frames over L4
(UDP) on the XL710 MAC, since there was a product decision to defeature
it. Fixed a previous refactor of active filters which caused issues in
the accounting of active_filters. Remaining work was done in the VLAN
filters to improve readability and simplify code as much as possible
to reduce inconsistencies.
Alex fixes foul budget accounting in core code by returning actual
work done, capped to budget-1.
Henry fixes the "ethtool -p" function for 1G BaseT PHYs.
Carolyn adds support for 25G devices for i40e and i40evf.
Michal adds functions to apply the correct access method for external PHYs
which could use Clause22 or Clause45 depending on the PHY.

Commit 3e3aaf649416 ("phy: fix mdiobus module safety") fixed the way we
dealt with MDIO bus module reference count, but sort of introduced a
regression in that, if an Ethernet driver registers its own MDIO bus
driver, as is common, we will end up with the Ethernet driver's
module->refnct set to 1, thus preventing this driver from any removal.
Fix this by comparing the network device's device driver owner against
the MDIO bus driver owner, and only if they are different, increment the
MDIO bus module refcount.

The CPTS drivers uses 8sec period for overflow checking with
assumption that CPTS retclk will not exceed 500MHz. But that's not
true on some TI platforms (Kesytone 2). As result, it is possible that
CPTS counter will overflow more than once between two readings.
Hence, fix it by selecting overflow check period dynamically as
max_sec_before_overflow/2, where
max_sec_before_overflow = max_counter_val / rftclk_freq.

The current implementation CPTS initialization and deinitialization
(represented by cpts_register/unregister()) does too many static
initialization from .ndo_open(), which is reasonable to do once at probe
time instead, and also require caller to allocate memory for struct cpts,
which is internal for CPTS driver in general.
This patch splits CPTS initialization and deinitialization on two parts:
- static initializtion cpts_create()/cpts_release() which expected to be
executed when parent driver is probed/removed;
- dynamic part cpts_register/unregister() which expected to be executed
when network device is opened/closed.
As result, current code of CPTS parent driver - CPSW - will be simplified
(and it also will allow simplify adding support for Keystone 2 devices in
the future), plus more initialization errors will be catched earlier. In
addition, this change allows to clean up cpts.h for the case when CPTS is

Since the network driver and RDMA driver operate on the same PCI function,
we need to create an interface to allow the RDMA driver to share resources
with the network driver.
1. Create a new bnxt_en_dev struct which will be returned by
bnxt_ulp_probe() upon success. After that, all calls from the RDMA driver
to bnxt_en will pass a pointer to this struct.
2. This struct contains additional function pointers to register, request
msix, send fw messages, register for async events.
3. If the RDMA driver wants to enable RDMA on the function, it needs to
call the function pointer bnxt_register_device(). A ulp_ops structure
is passed for RCU protected upcalls from bnxt_en to the RDMA driver.
4. The RDMA driver can call firmware APIs using the bnxt_send_fw_msg()
function pointer.
5. 1 stats context is reserved when the RDMA driver registers. MSIX
and completion rings are reserved when the RDMA driver calls
bnxt_request_msix() function pointer.
6. When the RDMA driver calls bnxt_unregister_device(), all RDMA resources
will be cleaned up.

from bnxt_open() to bnxt_init_one(). This way, MSIX vectors are available
to the RDMA driver whether the network device is up or down.
Part of the existing bnxt_setup_int_mode() function is now refactored into
a new bnxt_init_int_mode(). bnxt_init_int_mode() is called during
bnxt_init_one() to enable MSIX. The remaining logic in
bnxt_setup_int_mode() to map the IRQs to the completion rings is called
during bnxt_open().

In a similar fashion to how we handled exiting VLAN mode, move the logic
in i40e_vsi_add_vlan into i40e_sync_vsi_filters. Extract this logic into
its own function for ease of understanding as it will become quite
complex.
The new function, i40e_correct_mac_vlan_filters() correctly updates all
filters for when we need to enter VLAN mode, exit VLAN mode, and also
enforces the PVID when assigned.
Call i40e_correct_mac_vlan_filters from i40e_sync_vsi_filters passing it
the number of active VLAN filters, and the two temporary lists.
Remove the function for updating VLAN=0 filters from i40e_vsi_add_vlan.
The end result is that the logic for entering and exiting VLAN mode is
in one location which has the most knowledge about all filters. This
ensures that we always correctly have the non-VLAN filters assigned to
VID=0 or VID=-1 regardless of how we ended up getting to this result.
Additionally this enforces the PVID at sync time so that we know for
certain that an assigned PVID results in only filters with that PVID
will be added to the firmware.
