Eliminate one check in the data path and move it elsewhere, to where our
real limitation is. We'll want to start processing "too long" frames in
the driver (currently there is a hardware MAC setting which drops
theses).

Currently, the .port_set_rgmii_delay hook is missing for the 88E6320
family, which causes failure to retrieve an IP address via DHCP.
Add mv88e6320_port_set_rgmii_delay() that allows applying the RGMII
delay for ports 2, 5, and 6, which are the only ports that can be used
in RGMII mode.
Tested on a custom i.MX8MN board connected to an 88E6320 switch.
This change also applies safely to the 88E6321 variant.
The only difference between 88E6320 versus 88E6321 is the temperature
grade and pinout.
They share exactly the same MDIO register map for ports 2, 5, and 6,
which are the only ports that can be used in RGMII mode.

====================
rtnetlink: Honour NLM_F_ECHO flag in rtnl_{new, del}link
Netlink messages are used for communicating between user and kernel space.
When user space configures the kernel with netlink messages, it can set the
NLM_F_ECHO flag to request the kernel to send the applied configuration back
to the caller. This allows user space to retrieve configuration information
that are filled by the kernel (either because these parameters can only be
set by the kernel or because user space let the kernel choose a default
value).
The kernel has support this feature in some places like RTM_{NEW, DEL}ADDR,
RTM_{NEW, DEL}ROUTE. This patch set handles NLM_F_ECHO flag and send link
info back after rtnl_{new, del}link.

This patch use the new helper unregister_netdevice_many_notify() for
rtnl_delete_link(), so that the kernel could reply unicast when userspace
set NLM_F_ECHO flag to request the new created interface info.
At the same time, the parameters of rtnl_delete_link() need to be updated
since we need nlmsghdr and portid info.

====================
ptp: convert drivers to .adjfine
Many drivers implementing PTP have not yet migrated to the new .adjfine
frequency adjustment implementation.
A handful of these drivers use hardware with a simple increment value which
is adjusted by multiplying by the adjustment factor and then dividing by
1 billion. This calculation is very easy to convert to .adjfine, by simply
updating the divisor.
Introduce new helper functions, diff_by_scaled_ppm and adjust_by_scaled_ppm
which perform the most common calculations used by drivers for this purpose.
The adjust_by_scaled_ppm takes the base increment and scaled PPM value, and
calculates the new increment to use.
A few drivers need the difference and direction rather than a raw increment
value. The diff_by_scaled_ppm calculates the difference and returns true if
it should be a subtraction, false otherwise. This most closely aligns with
existing driver implementations.
I previously submitted v1 of this series at [1], and got some feedback only
on a handful of drivers. In the interest of merging the changes which have
received feedback, I've dropped the following drivers out of this send:
* ptp_phc
* ptp_ipx46x
* tg3
* hclge
* stmac
* cpts
I plan to submit those drivers changes again at a later date. As before,
there are some drivers which are not trivial to convert to the new helper
functions. While they may be able to work, their implementation is different
and I lack the hardware or datasheets to determine what the correct
implementation would be.
* drivers/net/ethernet/broadcom/bnx2x
* drivers/net/ethernet/broadcom/bnxt
* drivers/net/ethernet/cavium/liquidio
* drivers/net/ethernet/chelsio/cxgb4
* drivers/net/ethernet/freescale
* drivers/net/ethernet/qlogic/qed
* drivers/net/ethernet/qlogic/qede
* drivers/net/ethernet/sfc
* drivers/net/ethernet/sfc/siena
* drivers/net/ethernet/ti/am65-cpts.c
* drivers/ptp/ptp_dte.c
My end goal is to drop the .adjfreq implementation entirely, and to that end
I plan on modifying these drivers in the future to directly use
scaled_ppm_to_ppb as the simplest method to convert them.
Changes since v2:
* Rebased to allow landing in 6.2
* Added Richard's Acked-by

Many drivers implement the .adjfreq or .adjfine PTP op function with the
same basic logic:
1. Determine a base frequency value
2. Multiply this by the abs() of the requested adjustment, then divide by
the appropriate divisor (1 billion, or 65,536 billion).
3. Add or subtract this difference from the base frequency to calculate a
new adjustment.
A few drivers need the difference and direction rather than the combined
new increment value.
I recently converted the Intel drivers to .adjfine and the scaled parts per
million (65.536 parts per billion) logic. To avoid overflow with minimal
loss of precision, mul_u64_u64_div_u64 was used.
The basic logic used by all of these drivers is very similar, and leads to
a lot of duplicate code to perform the same task.
Rather than keep this duplicate code, introduce diff_by_scaled_ppm and
adjust_by_scaled_ppm. These helper functions calculate the difference or
adjustment necessary based on the scaled parts per million input.
The diff_by_scaled_ppm function returns true if the difference should be
subtracted, and false otherwise.
Update the Intel drivers to use the new helper functions. Other vendor
drivers will be converted to .adjfine and this helper function in the
following changes.

The queue configuration is referenced by snps,mtl-rx-config and

referenced config nodes directly beneath the root node, but
most in-tree DTs put it as child node of the dwmac node.
This adds proper description for this setup, which has the
advantage of validating the queue configuration node content.
The example is also updated to use the sub-node style, incl.
the axi bus configuration node, which got the same treatment
as the queues config in 5361660af6d3 ("dt-bindings: net: snps,dwmac:

s3fwrn5_nci_send(),
nfcmrvl_nci_send(),
st_nci_send();
1. virtual_nci_send() will memleak the skb, and has been fixed before.
2. fdp_nci_send() won't free the skb no matter whether write() succeed.
3-4. nxp_nci_send() and s3fwrn5_nci_send() will only free the skb when
write() failed, however write() will not free the skb by itself for when
succeeds.
5. nfcmrvl_nci_send() will call nfcmrvl_XXX_nci_send(), where some of
them will free the skb, but nfcmrvl_i2c_nci_send() only free the skb
when i2c_master_send() return >=0, and memleak will happen when
i2c_master_send() failed in nfcmrvl_i2c_nci_send().
6. st_nci_send() will queue the skb into other list and finally be
freed.
Fix the potential memory leak of skb.

nfcmrvl_i2c_nci_send() will be called by nfcmrvl_nci_send(), and skb
should be freed in nfcmrvl_i2c_nci_send(). However, nfcmrvl_nci_send()
will only free skb when i2c_master_send() return >=0, which means skb
will memleak when i2c_master_send() failed. Free skb no matter whether
i2c_master_send() succeeds.

s3fwrn5_nci_send() will call s3fwrn5_i2c_write() or s3fwrn82_uart_write(),
and free the skb if write() failed. However, even if the write() run
succeeds, the skb will not be freed in write(). As the result, the skb
will memleak. s3fwrn5_nci_send() should also free the skb when write()
succeeds.

nxp_nci_send() will call nxp_nci_i2c_write(), and only free skb when
nxp_nci_i2c_write() failed. However, even if the nxp_nci_i2c_write()
run succeeds, the skb will not be freed in nxp_nci_i2c_write(). As the
result, the skb will memleak. nxp_nci_send() should also free the skb
when nxp_nci_i2c_write() succeeds.

fdp_nci_send() will call fdp_nci_i2c_write that will not free skb in
the function. As a result, when fdp_nci_i2c_write() finished, the skb
will memleak. fdp_nci_send() should free skb after fdp_nci_i2c_write()
finished.
