The walk implementation of most qdisc class modules is basically the
same. That is, the values of count and skip are checked first. If
count is greater than or equal to skip, the registered fn function is
executed. Otherwise, increase the value of count. So we can reconstruct
them.

====================
Support 256 bit TLS keys with device offload
This series adds support for 256 bit TLS keys with device offload, and a
cleanup patch to remove repeating code:
- Patches #1-2 add cipher sizes descriptors which allow reducing the
amount of code duplications.
- Patch #3 allows 256 bit keys to be TX offloaded in the tls module (RX
already supported).
- Patch #4 adds 256 bit keys support to the mlx5 driver.

Any change to the hardware timestamps configuration triggers nic restart,
which breaks transmition and reception of network packets for a while.
But there is no need to fully restart the device because while configuring
hardware timestamps. The code for changing configuration runs after all
of the initialisation, when the NIC is actually up and running. This patch
changes the code that ioctl will only update configuration registers and
will not trigger carrier status change, but in case of timestamps for
all rx packetes it fallbacks to close()/open() sequnce because of
synchronization issues in the hardware. Tested on BCM57504.

A handful of awaited fixes here - revert of the FEC changes,
bluetooth fix, fixes for iwlwifi spew.
We added a warning in PHY/MDIO code which is triggering on
a couple of platforms in a false-positive-ish way. If we can't
iron that out over the week we'll drop it and re-add for 6.1.
I've added a new "follow up fixes" section for fixes to fixes
in 6.0-rcs but it may actually give the false impression that
those are problematic or that more testing time would have
caught them. So likely a one time thing.
Follow up fixes:
- nf_tables_addchain: fix nft_counters_enabled underflow
- ebtables: fix memory leak when blob is malformed
- nf_ct_ftp: fix deadlock when nat rewrite is needed
Current release - regressions:
- Revert "fec: Restart PPS after link state change"
- Revert "net: fec: Use a spinlock to guard `fep->ptp_clk_on`"
- Bluetooth: fix HCIGETDEVINFO regression
- wifi: mt76: fix 5 GHz connection regression on mt76x0/mt76x2
- mptcp: fix fwd memory accounting on coalesce
- rwlock removal fall out:

When reading the timestamp is required bnxt_tx_int() hands
over the ownership of the completed skb to the PTP worker.
The skb should not be used afterwards, as the worker may
run before the rest of our code and free the skb, leading
to a use-after-free.
Since dev_kfree_skb_any() accepts NULL make the loss of
ownership more obvious and set skb to NULL.

In prestera_port_sfp_bind(), there are two refcounting bugs:
(1) we should call of_node_get() before of_find_node_by_name() as
it will automaitcally decrease the refcount of 'from' argument;
(2) we should call of_node_put() for the break of the iteration
for_each_child_of_node() as it will automatically increase and
decrease the 'child'.

There is a separate receive path for small packets (under 256 bytes).
Instead of allocating a new dma-capable skb to be used for the next packet,
this path allocates a skb and copies the data into it (reusing the existing
sbk for the next packet). There are two bytes of junk data at the beginning
of every packet. I believe these are inserted in order to allow aligned DMA
and IP headers. We skip over them using skb_reserve. Before copying over
the data, we must use a barrier to ensure we see the whole packet. The
current code only synchronizes len bytes, starting from the beginning of
the packet, including the junk bytes. However, this leaves off the final
two bytes in the packet. Synchronize the whole packet.
To reproduce this problem, ping a HME with a payload size between 17 and
214
$ ping -s 17 <hme_address>
which will complain rather loudly about the data mismatch. Small packets
(below 60 bytes on the wire) do not have this issue. I suspect this is
related to the padding added to increase the minimum packet size.

Fix a NULL dereference of the struct bonding.rr_tx_counter member because
if a bond is initially created with an initial mode != zero (Round Robin)
the memory required for the counter is never created and when the mode is
changed there is never any attempt to verify the memory is allocated upon
switching modes.

Since commit ece19502834d ("net: phy: micrel: 1588 support for LAN8814
phy") the handler always returns IRQ_HANDLED, except in an error case.
Before that commit, the interrupt status register was checked and if
it was empty, IRQ_NONE was returned. Restore that behavior to play nice
with the interrupt line being shared with others.
