This big patch sprinkles const on local variables and
function arguments which may refer to netdev->dev_addr.
Commit 406f42fa0d ("net-next: When a bond have a massive amount
of VLANs...") introduced a rbtree for faster Ethernet address look
up. To maintain netdev->dev_addr in this tree we need to make all
the writes to it got through appropriate helpers.
Some of the changes here are not strictly required - const
is sometimes cast off but pointer is not used for writing.
It seems like it's still better to add the const in case
the code changes later or relevant -W flags get enabled
for the build.
No functional changes.

100GbE Intel Wired LAN Driver Updates 2021-10-14
Extend the driver implementation to support PTP pins on E810-T
and derivative devices.
E810-T adapters are equipped with:
- 2 external bidirectional SMA connectors
- 1 internal TX U.FL shared with SMA1
- 1 internal RX U.FL shared with SMA2
The SMA and U.FL configuration is controlled by the external
multiplexer.
E810-T Derivatives are equipped with:
- 2 1PPS outputs on SDP20 and SDP22
- 2 1PPS inputs on SDP21 and SDP23

In icmp_build_probe(), the icmp_ext_echo_iio parsing should be done
step by step and skb_header_pointer() return value should always be
checked, this patch fixes 3 places in there:
- On case ICMP_EXT_ECHO_CTYPE_NAME, it should only copy ident.name
from skb by skb_header_pointer(), its len is ident_len. Besides,
the return value of skb_header_pointer() should always be checked.
- On case ICMP_EXT_ECHO_CTYPE_INDEX, move ident_len check ahead of
skb_header_pointer(), and also do the return value check for
skb_header_pointer().
- On case ICMP_EXT_ECHO_CTYPE_ADDR, before accessing iio->ident.addr.
ctype3_hdr.addrlen, skb_header_pointer() should be called first,
then check its return value and ident_len.
On subcases ICMP_AFI_IP and ICMP_AFI_IP6, also do check for ident.
addr.ctype3_hdr.addrlen and skb_header_pointer()'s return value.
On subcase ICMP_AFI_IP, the len for skb_header_pointer() should be
"sizeof(iio->extobj_hdr) + sizeof(iio->ident.addr.ctype3_hdr) +
sizeof(struct in_addr)" or "ident_len".
v1->v2:
- To make it more clear, call skb_header_pointer() once only for
iio->indent's parsing as Jakub Suggested.
v2->v3:
- The extobj_hdr.length check against sizeof(_iio) should be done
before calling skb_header_pointer(), as Eric noticed.

Expose SMA and U.FL connectors as ptp_pins on E810-T based adapters and
allow controlling them.
E810-T adapters are equipped with:
- 2 external bidirectional SMA connectors
- 1 internal TX U.FL
- 1 internal RX U.FL
U.FL connectors share signal lines with the SMA connectors. The TX U.FL1
share the line with the SMA1 and the RX U.FL2 share line with the SMA2.
This dependence is controlled by the ice_verify_pin_e810t.
Additionally add support for the E810-T-based devices which don't use the
SMA/U.FL controller. If the IO expander is not detected don't expose pins
and use 2 predefined 1PPS input and output pins.

Currently, mlxsw allows cooling states to be set above the maximum
cooling state supported by the driver:
# cat /sys/class/thermal/thermal_zone2/cdev0/type
mlxsw_fan
# cat /sys/class/thermal/thermal_zone2/cdev0/max_state
10
# echo 18 > /sys/class/thermal/thermal_zone2/cdev0/cur_state
# echo $?
0
This results in out-of-bounds memory accesses when thermal state
transition statistics are enabled (CONFIG_THERMAL_STATISTICS=y), as the
transition table is accessed with a too large index (state) [1].
According to the thermal maintainer, it is the responsibility of the
driver to reject such operations [2].
Therefore, return an error when the state to be set exceeds the maximum
cooling state supported by the driver.
To avoid dead code, as suggested by the thermal maintainer [3],
partially revert commit a421ce088a ("mlxsw: core: Extend cooling
device with cooling levels") that tried to interpret these invalid
cooling states (above the maximum) in a special way. The cooling levels
array is not removed in order to prevent the fans going below 20% PWM,
which would cause them to get stuck at 0% PWM.

Change it to instead call the low-level do_s2io_prog_unicast() function

this was removed in commit 8a29581eb0 ("mlxsw: spectrum: Move the

On Spectrum-3, a per-TC number of ECN-marked packets is available in per-TC
congestion counter group. Add a new array for the ECN counter, fetch the
values from the per-TC congestion group, and pick the value indicated by
tclass_num as appropriate.

The implication is that ds->ops->teardown cannot emit cross-chip
notifiers. For example, currently the dsa_tag_8021q_unregister() call
from sja1105_teardown() does not propagate to the entire tree due to
this reason. However I cannot find an actual issue caused by this,
observed using code inspection.

Make the drivers which use single-byte netdev addresses
(netdev->addr_len == 1) use the appropriate address setting
helpers.
arcnet copies from int variables and io reads a lot, so
add a helper for arcnet drivers to use.
Similar helper could be reused for phonet and appletalk
but there isn't any good central location where we could
put it, and netdevice.h is already very crowded.

__dev_addr_set() and dev_addr_mod() and pretty low level,
let the arguments be void, there's no chance for confusion
in callers converted to use them. Keep u8 in dev_addr_set()
because some of the callers are converted from a loop
and we want to make sure assignments are not from an array
of a different type.

net: constify dev_addr passing for protocols
Commit 406f42fa0d ("net-next: When a bond have a massive amount
of VLANs...") introduced a rbtree for faster Ethernet address look
up. To maintain netdev->dev_addr in this tree we need to make all
the writes to it got through appropriate helpers.
netdev->dev_addr will be made const to prevent direct writes.
This set sprinkles const across variables and arguments in protocol
code which are used to hold references to netdev->dev_addr.

Add functional support for Gigabit Ethernet driver
The DMAC and EMAC blocks of Gigabit Ethernet IP found on RZ/G2L SoC are
similar to the R-Car Ethernet AVB IP.
The Gigabit Ethernet IP consists of Ethernet controller (E-MAC), Internal
TCP/IP Offload Engine (TOE) and Dedicated Direct memory access controller
(DMAC).
With a few changes in the driver we can support both IPs.
This patch series is aims to add functional support for Gigabit Ethernet
driver by filling all the stubs except set_features.
set_feature patch will send as separate RFC patch along with rx_checksum
patch, as it needs further discussion related to HW checksum.
With this series, we can do boot kernel with rootFS mounted on NFS on
RZ/G2L platforms.
