mwifiex_get_random_ba_threshold() uses a complex homegrown implementation
to generate a pseudo-random number from the current time as returned
from do_gettimeofday().
This currently requires two 32-bit divisions plus a couple of other
computations that are eventually discarded as only eight bits of
the microsecond portion are used at all.
We could replace this with a call to get_random_bytes(), but that
might drain the entropy pool too fast if this is called for each
packet.
Instead, this patch converts it to use ktime_get_ns(), which is a
bit faster than do_gettimeofday(), and then uses a similar algorithm
as before, but in a way that takes both the nanosecond and second
portion into account for slightly-more-but-still-not-very-random
pseudorandom number.

The mwifiex_11n_aggregate_pkt() function creates a ktime_t from
a timeval returned by do_gettimeofday, which is slow and causes
an overflow in 2038 on 32-bit architectures.
This solves both problems by using the appropriate ktime_get_real()
function.

We want to deprecate the use of 'struct timespec' on 32-bit
architectures, as it is will overflow in 2038. The igb
driver uses it to read the current time, and can simply
be changed to use ktime_get_real_ts64() instead.
Because of hardware limitations, there is still an overflow
in year 2106, which we cannot really avoid, but this documents
the overflow.

The fec_ptp_enable_pps uses an open-coded implementation of ns_to_timespec,
which will be removed eventually as it is not y2038-safe on 32-bit
architectures. Two more instances of the same code in this file were
already converted to use the safe ns_to_timespec64 in commit 6630514fcee
("ptp: fec: use helpers for converting ns to timespec"), this changes
the last one as well.
The seconds portion here is actually unused and we could just remove the
timespec variable, but using ns_to_timespec64 can still be better as the
implementation can be hand-optimized in the future.

====================
Intel Wired LAN Driver Updates 2015-09-30
This series contains updates to i40e and i40evf only.
Vasily Averin provides a couple of rtnl lock/unlock fixes for both i40e
and i40evf.
Shannon provides several updates and fixes, first fixes up a type clash
in i40e_aq_rc_to_posix(), where the error codes are signed values, so we
need to treat them as such. Then fixes up a padding issue where an
extra byte is added in i40e_aqc_get_cee_dcb_cfg_v1_resp to directly
acknowledge the padding. Updated i40e to keep debugfs register read
and writes from accessing outside of the io-remapped space. Added
support and device id for another 20 GbE device.
Jesse fixes the transmit hand workaround code for ARM that was causing
Tx hangs to still occur occasionally when there really was no hang. Then
fixed the receive dropped counter to show up in netstat interface.
Refactor the interrupt enable function since it was always making the
caller add the base_vector from the VSI struct which is already passed
to the function. Fix kbuild warnings found in 0day build infrastructure
by adding a harmless cast to a dev_info(), also fix 32 bit build
warnings found by sparse.
Greg fixed a configuration error that results if a port VLAN is set
for a VF before the VF driver is loaded, so that when the VF driver is
loaded the port VLAN is ignored.
Mitch fixes the use of QOS field consistently in
i40e_ndo_set_vf_port_vlan(). Modified the init timing of the driver
to increase stability on load/unload and SR-IOV enable/disable cycles.
Anjali updates i40e to not collect VEB stats if they are disabled in the
hardware for performance reasons.

This patch supports the r8a7795 SoC by:
- Using two interrupts
+ One for E-MAC
+ One for everything else
+ Both can be handled by the existing common interrupt handler, which
affords a simpler update to support the new SoC. In future some
consideration may be given to implementing multiple interrupt handlers
- Limiting the phy speed to 100Mbit/s for the new SoC;
at this time it is not clear how this restriction may be lifted
but I hope it will be possible as more information comes to light

Add a helper to allow ethernet drivers to limit the speed of a phy
(that they are attached to).
This mainly involves factoring out the business-end of
of_set_phy_supported() and exporting a new symbol.
This code seems to be open coded in several places, in several different
variants.
It is is envisaged that this will be used in situations where setting the
"max-speed" property in DT is not appropriate, e.g. because the maximum
speed is not a property of the phy hardware.

This patch tweaks the init timing of the driver just a little bit to
increase stability on load/unload and SR-IOV enable/disable cycles.
First, run the init_task loop a little quicker in order to reduce
overall init time.
Second, stagger the start of the init task based on the device's
PCIe function ID. This lessens the impact on the firmware when a
whole bunch of VFs are initialized simultaneously, e.g. enabling
SR-IOV without the VF driver blacklisted. For single VFs assigned
to VMs this will have no effect as the function ID will always be 0.

Down was requesting queue disables, but then exited immediately without
waiting for the queues to actually disable. This could allow any
function called after i40evf_down to run immediately, including
i40evf_up, and causes a memory leak.
This issue has been fixed in a recent refactor of the reset code, but
add a couple WARN_ONs in the slow path to help us recognize if we
reintroduce this issue or if we missed any cases.

The arm writeback (arm_wb) code is used for kicking the Tx ring to
make sure any pending work is completed even if interrupts are
disabled. It was running when it didn't need to, and not clearing
the ring->arm_wb state after it was set. This caused Tx hangs
to still occur occasionally when there really was no hang.
Fix this by resetting the variable right after it was used.

The struct i40e_aqc_get_cee_dcb_cfg_v1_resp was originally defined with
word boundary layout issues, which most compilers deal with by silently
adding padding, making the actual struct larger than designed.
This patch adds an extra byte in fields reserved3 and reserved4 to directly
acknowledge that padding.
Because the struct doesn't actually change in size or layout, this doesn't
constitute a change in the API.

commit dea870242a9c ("dsa: mv88e6xxx: Allow speed/duplex of port to be
configured") leads to the following static checker warning:
drivers/net/dsa/mv88e6xxx.c:585 mv88e6xxx_adjust_link()
warn: unsigned 'ret' is never less than zero.
drivers/net/dsa/mv88e6xxx.c
573 void mv88e6xxx_adjust_link(struct dsa_switch *ds, int port,
574 struct phy_device *phydev)
575 {
576 struct mv88e6xxx_priv_state *ps = ds_to_priv(ds);
577 u32 ret, reg;
578
579 if (!phy_is_pseudo_fixed_link(phydev))
580 return;

583
584 ret = _mv88e6xxx_reg_read(ds, REG_PORT(port), PORT_PCS_CTRL);
585 if (ret < 0)
Make ret an int, which is the return type for _mv88e6xxx_reg_read()

port. Otherwise incoming ARP, dhcp leases, etc, do not work.
