This makes the age information for cfg80211 scan results more accurate
and fixes issues with wpa_supplicant dropping "old" scan results (e.g.,
"wlan0: Own scan request started a scan in 0.000456 seconds") that
looked like would have been received before a scan started due to the
inaccuracy of the default timing mechanism for calculating the BSS entry
age. This makes hwsim test cases significantly more robust to run.

Sven Auhagen reports that if he changes a SFP+ module for a SFP module
on the Macchiatobin Single Shot, the link does not come back up. For
Sven, it is as easy as:
- Insert a SFP+ module connected, and use ping6 to verify link is up.
- Remove SFP+ module
- Insert SFP 1000base-X module use ping6 to verify link is up: Link
up event did not trigger and the link is down
but that doesn't show the problem for me. Locally, this has been
reproduced by:
- Boot with no modules.
- Insert SFP+ module, confirm link is up.
- Replace module with 25000base-X module. Confirm link is up.
- Set remote end down, link is reported as dropped at both ends.
- Set remote end up, link is reported up at remote end, but not local
end due to lack of link interrupt.
Fix this by setting up both GMAC and XLG interrupts for port 0, but
only unmasking the appropriate interrupt according to the current mode
set in the mac_config() method. However, only do the mask/unmask
dance when we are really changing the link mode to avoid missing any
link interrupts.

All users of the fixed_phy_add() pass -1 as GPIO number
to the fixed phy driver, and all users of fixed_phy_register()
pass -1 as GPIO number as well, except for the device
tree MDIO bus.
Any new users should create a proper device and pass the
GPIO as a descriptor associated with the device so delete
the GPIO argument from the calls and drop the code looking
requesting a GPIO in fixed_phy_add().
In fixed phy_register(), investigate the "fixed-link"
node and pick the GPIO descriptor from "link-gpios" if
this property exists. Move the corresponding code out
of of_mdio.c as the fixed phy code anyways requires

Add support for the RX checksum offload. This is enabled by default and
may be disabled and re-enabled using 'ethtool':
# ethtool -K eth0 rx off
# ethtool -K eth0 rx on
Some Ether MACs provide a simple checksumming scheme which appears to be
completely compatible with CHECKSUM_COMPLETE: sum of all packet data after
the L2 header is appended to packet data; this may be trivially read by
the driver and used to update the skb accordingly. The same checksumming
scheme is implemented in the EtherAVB MACs and now supported by the 'ravb'
driver.
In terms of performance, throughput is close to gigabit line rate with the
RX checksum offload both enabled and disabled. The 'perf' output, however,
appears to indicate that significantly less time is spent in do_csum() --
this is as expected.

net: y2038-safe socket timestamps
The series introduces new socket timestamps that are
y2038 safe.
The time data types used for the existing socket timestamp
options: SO_TIMESTAMP, SO_TIMESTAMPNS and SO_TIMESTAMPING
are not y2038 safe. The series introduces SO_TIMESTAMP_NEW,
SO_TIMESTAMPNS_NEW and SO_TIMESTAMPING_NEW to replace these.
These new timestamps can be used on all architectures.
The alternative considered was to extend the sys_setsockopt()
by using the flags. We did not receive any strong opinions about
either of the approaches. Hence, this was chosen, as glibc folks
preferred this.
The series does not deal with updating the internal kernel socket
calls like rxrpc to make them y2038 safe. This will be dealt
with separately.
Note that the timestamps behavior already does not match the
man page specific behavior:
SIOCGSTAMP
This ioctl should only be used if the socket option SO_TIMESTAMP
is not set on the socket. Otherwise, it returns the timestamp of
the last packet that was received while SO_TIMESTAMP was not set,
or it fails if no such packet has been received,
(i.e., ioctl(2) returns -1 with errno set to ENOENT).
The recommendation is to update the man page to remove the above statement.
The overview of the socket timestamp series is as below:
1. Delete asm specific socket.h when possible.
2. Support SO/SCM_TIMESTAMP* options only in userspace.
3. Rename current SO/SCM_TIMESTAMP* to SO/SCM_TIMESTAMP*_OLD.
3. Alter socket options so that SOCK_RCVTSTAMPNS does
not rely on SOCK_RCVTSTAMP.
4. Introduce y2038 safe types for socket timestamp.
5. Introduce new y2038 safe socket options SO/SCM_TIMESTAMP*_NEW.
6. Intorduce new y2038 safe socket timeout options.
Changes since v4:
* Fixed the typo in calling sock_get_timeout()
Changes since v3:
* Rebased onto net-next and fixups as per review comments
* Merged the socket timeout series
* Integrated Arnd's patch to simplify compat handling of timeout syscalls
Changes since v2:
* Removed extra functions to reduce diff churn as per code review
Changes since v1:
* Dropped the change to disentangle sock flags
* Renamed sock_timeval to __kernel_sock_timeval
* Updated a few comments
* Added documentation changes
====================
Signed-off-by: David S. Miller <davem@davemloft.net>
SO_RCVTIMEO and SO_SNDTIMEO socket options use struct timeval
as the time format. struct timeval is not y2038 safe.
The subsequent patches in the series add support for new socket
timeout options with _NEW suffix that will use y2038 safe
data structures. Although the existing struct timeval layout
is sufficiently wide to represent timeouts, because of the way
libc will interpret time_t based on user defined flag, these
new flags provide a way of having a structure that is the same
for all architectures consistently.
Rename the existing options with _OLD suffix forms so that the
right option is enabled for userspace applications according
to the architecture and time_t definition of libc.

The new type is meant to be used as a y2038 safe structure

Presently the SO_TIMESTAMP socket option uses struct timeval
for timestamps. This is not y2038 safe.
Subsequent patches in the series add new y2038 safe socket
option to be used in the place of SO_TIMESTAMP_OLD.
struct __kernel_sock_timeval will be used as the timestamp
format at that time.
struct __kernel_sock_timeval also maintains the same layout

in O_SNDTIMEO/O_RCVTIMEO. The existing compat handler seems

main setsockopt()/getsockopt() implementation requires half
as much code and is easier to extend.
