Small merge conflict in net/mac80211/scan.c, I preserved
the kcalloc() conversion. -DaveM
Johannes Berg says:
====================
This round's updates:
* finally some of the promised HE code, but it turns
out to be small - but everything kept changing, so
one part I did in the driver was >30 patches for
what was ultimately <200 lines of code ... similar
here for this code.
* improved scan privacy support - can now specify scan
flags for randomizing the sequence number as well as
reducing the probe request element content
* rfkill cleanups
* a timekeeping cleanup from Arnd
* various other cleanups

The very first version of RTL8169 from 2002 (and only this one) has
support for a TBI 1000BaseX fiber interface. The TBI support in the
driver makes switching to phylib tricky, so best would be to get
rid of it. I found no report from anybody using a device with RTL8169
and fiber interface, also the vendor driver doesn't support this mode
(any longer).
So remove TBI support and bail out with a message if a card with
activated TBI is detected. If there really should be any user of it
out there, we could add a stripped-down version of the driver
supporting chip version 01 and TBI only (and maybe move it to
staging).

In preparation of adding phylib support to the r8169 driver we need
PHY drivers for all chip-internal PHY types. Fortunately almost all
of them are either supported by the Realtek PHY driver already or work
with the genphy driver.
Still missing is support for the PHY of RTL8169s, it requires a quirk
to properly support 100Mbit-fixed mode. The quirk was copied from
r8169 driver which copied it from the vendor driver.
Based on the PHYID the internal PHY seems to be a RTL8211.

I see no need to define a private debug output symbol, let's use the

the deprecated PFX define.
The one assertion is wrong IMO anyway, this code path is used also

PPv2's Header Parser use some large TCAM and SRAM entries, that are
duplicated in software so that we can write them to hardware only when
we are done modifying them.
Currently, PPv2 uses a union containing arrays of u32 and u8 to represent
these entries, to facilitate byte per byte access. This representation is
broken when we want to support big endian, and this makes the code
confusing to read.
This patch drops the union, and simply stores the TCAM and SRAM entries
as u32 arrays, each entry corresponding to a 32-bit register.

Driver performs the internal reload when it receives tx-timeout event from
the OS. Internal reload might fail in some scenarios e.g., fatal HW issues.
In such cases OS still see the link, which would result in undesirable
functionalities such as re-generation of tx-timeouts.
The patch addresses this issue by indicating the link-down to OS when
tx-timeout is detected, and keeping the link in down state till the
internal reload is successful.
Please consider applying it to 'net' branch.

Static checkers complain that id_tbl->table points to longs and 4 bytes
is smaller than sizeof(long). But the since other side is dividing by
32 instead of sizeof(long), that means the current code works fine.
Anyway, it's more conventional to use the BITS_TO_LONGS() macro when
we're allocating a bitmap.

mlx5e-updates-2018-06-28
mlx5e netdevice driver updates:
- Boris Pismenny added the support for UDP GSO in the first two patches.
Impressive performance numbers are included in the commit message,
@Line rate with ~half of the cpu utilization compared to non offload
or no GSO at all.
- From Tariq Toukan:
- Convert large order kzalloc allocations to kvzalloc.
- Added performance diagnostic statistics to several places in data path.
From Saeed and Eran,
- Update NIC HW stats on demand only, this is to eliminate the background
thread needed to update some HW statistics in the driver cache in
order to report error and drop counters from HW in ndo_get_stats.

The present TX workrequest(FW_ETH_TX_PKT_WR) cant be used for
host->vf communication, since it doesn't loopback the outgoing
packets to virtual interfaces on the same port. This can be done
using FW_ETH_TX_PKT_VM_WR.
This fix depends on ethtool_flags to determine what WR to use for
TX path. Support for setting this flags by user is added in next
commit.

Disable periodic stats update background thread and update stats in
background on demand when ndo_get_stats is called.
Having a background thread running in the driver all the time is bad for
power consumption and normally a user space daemon will query the stats
once every specific interval, so ideally the background thread and its
interval can be done in user space..

This patch enables UDP GSO support. We enable this by using two WQEs
the first is a UDP LSO WQE for all segments with equal length, and the
second is for the last segment in case it has different length.
Due to HW limitation, before sending, we must adjust the packet length fields.
We measure performance between two Intel(R) Xeon(R) CPU E5-2643 v2 @3.50GHz
machines connected back-to-back with Connectx4-Lx (40Gbps) NICs.
We compare single stream UDP, UDP GSO and UDP GSO with offload.
Performance:
| MSS (bytes) | Throughput (Gbps) | CPU utilization (%)
UDP GSO offload | 1472 | 35.6 | 8%
UDP GSO | 1472 | 25.5 | 17%
