Some MAC hardware cannot support a subset of link modes. e.g. often
1Gbps Full duplex is supported, but Half duplex is not. Add a helper
to remove such a link mode.

PHY drivers don't indicate they support pause. They expect MAC drivers
to enable its support if the MAC has the needed hardware. Thus MAC
drivers should not mask Pause support, but enable it.

The phy supported speed is being used to determine if the MAC should
be configured to 100 or 1G. The masking logic is broken. Instead, look
at 1G supported speeds to enable 1G MAC support.

Essentially reverts commit 8fd75c58a09a ("i40e: move ethtool
stats boiler plate code to i40e_ethtool_stats.h", 2018-08-30), and
additionally moves the similar code in i40evf into i40evf_ethtool.c.
The code was intially moved from i40e_ethtool.c into i40e_ethtool_stats.h
as a way of better logically organizing the code. This has two problems.
First, we can't have an inline function with variadic arguments on all
platforms. Second, it gave the appearance that we had plans to share
code between the i40e and i40evf drivers, due to having a near copy of
the contents in the i40evf/i40e_ethtool_stats.h file.
Patches which actually attempt to combine or share code between the i40e
and i40evf drivers have not materialized, and are likely a ways off.
Rather than fixing the one function which causes build issues, just move
this code back into the i40e_ethtool.c and i40evf_ethtool.c files. Note
that we also change these functions back from static inlines to just
statics, since they're no longer in a header file.
We can revisit this if/when work is done to actually attempt to share
code between drivers. Alternatively, this stats code could be made more
generic so that it can be shared across drivers as part of ethtool
kernel work.

====================
mlx5e-updates-2018-09-05
This series provides updates to mlx5 ethernet driver.
1) Starting with a four patches series to optimize flow counters updates,
From Vlad Buslov:
==============================================
By default mlx5 driver updates cached counters each second. Update function
consumes noticeable amount of CPU resources. The goal of this patch series
is to optimize update function.
Investigation revealed following bottlenecks in fs counters
implementation:
1) Update code(scheduled each second) iterates over all counters twice.
(first for finding and deleting counters that are marked for deletion,
second iteration is for actually updating the counters)
2) Counters are stored in rb tree. Linear iteration over all rb tree
elements(rb_next in profiling data) consumed ~65% of time spent in
update function.
Following optimizations were implemented:
1) Instead of just marking counters for deletion, store them in
standalone list. This removes first iteration over whole counters tree.
2) Store counters in sorted list to optimize traversing them and remove
calls to rb_next.
First implementation of these changes caused degradation of performance,
instead of improving it. Investigation revealed that there first cache
line of struct mlx5_fc is full and adding anything to it causes amount
of cache misses to double. To mitigate that, following refactorings were
implemented:
- Change 'addlist' list type from double linked to single linked. This
allowes to get free space for one additional pointer that is used to
store deletion list(optimization 1)
- Substitute rb tree with idr. Idr is non-intrusive data structure and
doesn't require adding any new members to struct mlx5_fc. Use free
space that became available for double linked sorted list that is used
for traversing all counters. (optimization 2)
Described changes reduced CPU time spent in mlx5_fc_stats_work from 70%
to 44%. (global perf profile mode)
============================================
The rest of the series are misc updates:
2) From Kamal, Move mlx5e_priv_flags into en_ethtool.c, to avoid a
compilation warning.
3) From Roi Dayan, Move Q counters allocation and drop RQ to init_rx profile
function to avoid allocating Q counters when not required.
4) From Shay Agroskin, Replace PTP clock lock from RW lock to seq lock.
Almost double the packet rate when timestamping is active on multiple TX
queues.
5) From: Natali Shechtman, set ECN for received packets using CQE indication.
6) From: Alaa Hleihel, don't set CHECKSUM_COMPLETE on SCTP packets.
CHECKSUM_COMPLETE is not applicable to SCTP protocol.
====================

In multi-host (MH) NIC scheme, a single HW port serves multiple hosts
or sockets on the same host.
The HW uses a mechanism in the PCIe buffer which monitors
the amount of consumed PCIe buffers per host.
On a certain configuration, under congestion,
the HW emulates a switch doing ECN marking on packets using ECN
indication on the completion descriptor (CQE).
The driver needs to set the ECN bits on the packet SKB,
such that the network stack can react on that, this commit does that.

Changed "priv.clock.lock" lock from 'rw_lock' to 'seq_lock'
in order to improve packet rate performance.
Tested on Intel(R) Xeon(R) CPU E5-2660 v2 @ 2.20GHz.
Sent 64b packets between two peers connected by ConnectX-5,
and measured packet rate for the receiver in three modes:
no time-stamping (base rate)
time-stamping using rw_lock (old lock) for critical region
time-stamping using seq_lock (new lock) for critical region
Only the receiver time stamped its packets.
The measured packet rate improvements are:
Single flow (multiple TX rings to single RX ring):
without timestamping: 4.26 (M packets)/sec
with rw-lock (old lock): 4.1 (M packets)/sec
with seq-lock (new lock): 4.16 (M packets)/sec
1.46% improvement
Multiple flows (multiple TX rings to six RX rings):
without timestamping: 22 (M packets)/sec
with rw-lock (old lock): 11.7 (M packets)/sec
with seq-lock (new lock): 21.3 (M packets)/sec
82.05% improvement
The packet rate improvement is due to the lack of atomic operations
for the 'readers' by the seq-lock.
Since there are much more 'readers' than 'writers' contention
on this lock, almost all atomic operations are saved.
this results in a dramatic decrease in overall
cache misses.

Previous patch in series changed flow counter storage structure from
rb_tree to linked list in order to improve flow counter traversal
performance. The drawback of such solution is that flow counter lookup by
id becomes linear in complexity.
Store pointers to flow counters in idr in order to improve lookup
performance to logarithmic again. Idr is non-intrusive data structure and
doesn't require extending flow counter struct with new elements. This means
that idr can be used for lookup, while linked list from previous patch is
used for traversal, and struct mlx5_fc size is <= 2 cache lines.

In order to improve performance of flow counter stats query loop that
traverses all configured flow counters, replace rb_tree with double-linked
list. This change improves performance of traversing flow counters by
removing the tree traversal. (profiling data showed that call to rb_next
was most top CPU consumer)
However, lookup of flow flow counter in list becomes linear, instead of
logarithmic. This problem is fixed by next patch in series, which adds idr
for fast lookup. Idr is to be used because it is not an intrusive data
structure and doesn't require adding any new members to struct mlx5_fc,
which allows its control data part to stay <= 1 cache line in size.

In order to prevent flow counters stats work function from traversing whole
flow counters tree while searching for deleted flow counters, new list to
store deleted flow counters is added to struct mlx5_fc_stats. Lockless
NULL-terminated single linked list data type is used due to following
reasons:
- This use case only needs to add single element to list and
remove/iterate whole list. Lockless list doesn't require any additional
synchronization for these operations.
- First cache line of flow counter data structure only has space to store
single additional pointer, which precludes usage of double linked list.
Remove flow counter 'deleted' flag that is no longer needed.
