The LAN743x includes on chip One-Time-Programmable (OTP) memory.
This patch extends the ethtool EEPROM read/write interface to
access OTP memory space.
The currently existing interface is limited, as it does not
allow OTP read, and OTP writes are restricted to
offset==0, length==512, and data[0]==0xF3.
This patch removes these restrictions and adds a private flag
called OTP_ACCESS, which is used to switch between EEPROM, and
OTP modes.
The private flag OTP_ACCESS is configurable through the
ethtool --set-priv-flags command.
And visible through the
ethtool --show-priv-flags command.
By default OTP_ACCESS is false, and there for previously existing
EEPROM commands will work exactly the same. However now access to
OTP requires one extra step of setting OTP_ACCESS to true. This
flag controls the read, write, and length reporting, functions
of ethtool.
EEPROM presence is not checked when setting or clearing this flag.
If the EEPROM is not present, the user, as before, will need to
diagnose that using existing read and write function of ethtool,
while OTP_ACCESS is false.
Updates for V2:
Added comments as to why this patch is needed.
Added comments explaining that EEPROM presence is not check
when setting or clearing the OTP_ACCESS flag.
Added length checking to all otp/eeprom read/write functions.

mlx5e_grp_sw_update_stats can be called from two threads,
1) ndo_get_stats64
2) get_ethtool_stats
For this reason and to minimize concurrency issue impact on 64bit machines
mlx5e_grp_sw_update_stats folds the software stats into a temporary
variable then copies it to the global driver stats, both ethtool and ndo
statistics callbacks will use the global software stats variable to report
whatever stats they need.
Actually ndo_get_stats64 doesn't need to fold the whole software stats
(mlx5e_grp_sw_update_stats), all it needs is five counters to fill the
rtnl_link_stats64 relevant stats parameter.
Hence this patch introduces a simpler helper function to fold software
stats for ndo_get_stats64 which will work directly on rtnl_link_stats64
stats parameter and not on the global or even temporary mlx5e_sw_stats
variable.
Since now mlx5e_grp_sw_update_stats is not called by ndo_get_stats64 we
can make it static and remove the temp var.
Unlike mlx5e_grp_sw_update_stats the new fold stats function doesn't
need to zero out the output statistics parameter since it is already
done by the stack @dev_get_stats().
This patch is fixing stack usage of mlx5e_grp_sw_update_stats on
x86 gcc-4.9 and higher, the concurrency issue between mlx5's
ndo_get_stats64 and get_ethtool_stats is resolved as well.

Currently we have one cpu in XPS cpumask per tx queue, this is good
enough for default configuration where there is a tx queue per cpu.
However, once configuration changes to use less tx queues, part of the
cpus are not XPS-mapped and so the select queue decision falls back to
hash calculation and balancing is not guaranteed.
Expand XPS cpumask to enable using all cpus even when number of tx
queues is smaller than number of cpus.

In the non-linear SKB memory scheme of Striding RQ, a packet header
could cross page boundary. This requires special care in fast path
that costs LoC, additional runtime instructions and branches.
It could happen when the header (up to 256B) does not fit in
a single stride. Avoid this by working with a stride size that fits
the maximum possible header. Stride is increased form 64B to 256B.
Performance:
Tested packet rate for UDP streams, single ring, on ConnectX-5.
Configuration:
Set Striding RQ and LRO ON (to enabled the non-linear SKB scheme).
GRO OFF, early drop by TC rule.
64B: 4x worse memory utilization, no page-crossers headers
- No degradation (5,887,305 pps).
- The reduction in memory utilization is compensated by the saving of
branches tests.
192B: 1.33x worse memory utilization, avoid page-crossers headers
- Before: 5,727,252. After: 5,777,037. ~1% gain.

With VF LAG commit 491c37e49b48 "net/mlx5e: In case of LAG, one switch
parent id is used for all representors", both uplinks and all the VFs
(on both of them) get the same switchdev id.
This cause the provisioning system method to identify the rep of a given
VF from the parent PF PCI device using switchev id and physical port
name to break, since VFm of PF0 will have the (id, name) as VFm of PF1.
To fix that, we align to use the framework agreed upstream and set by

Johannes Berg says:
====================
Just a few small fixes:
* avoid trying to operate TDLS when not connection,
this is not valid and led to issues
* count TTL-dropped frames in mesh better
* deal with new WiGig channels in regulatory code
* remove a WARN_ON() that can trigger due to benign
races during device/driver registration
* fix nested netlink policy maxattrs (syzkaller)
* fix hwsim n_limits (syzkaller)
* propagate __aligned(2) to a surrounding struct
* return proper error in virt_wifi error path

Klocwork complains about copying from dev_cmd->hdr if
copying more than 4 bytes since it means part of the
copy is from the next field. This isn't a real bug,
but for not failing Klocwork next time - fix this.
