flow_action_hw_stats_types_check() helper takes one of the
FLOW_ACTION_HW_STATS_*_BIT values as input. If we align
the arguments to the opening bracket of the helper there
is no way to call this helper and stay under 80 characters.

====================
net: phy: improve phy_driver callback handle_interrupt
did_interrupt() clears the interrupt, therefore handle_interrupt() can
not check which event triggered the interrupt. To overcome this
constraint and allow more flexibility for customer interrupt handlers,
let's decouple handle_interrupt() from parts of the phylib interrupt
handling. Custom interrupt handlers now have to implement the
did_interrupt() functionality in handle_interrupt() if needed.
Fortunately we have just one custom interrupt handler so far (in the
mscc PHY driver), convert it to the changed API and make use of the
benefits.

ethtool: consolidate irq coalescing - last part
Convert remaining drivers following the groundwork laid in a recent
patch set [1] and continued in [2], [3], [4], [5]. The aim of
the effort is to consolidate irq coalescing parameter validation
in the core.
This set is the sixth and last installment. It converts the remaining
8 drivers in drivers/net/ethernet. The last patch makes declaring
supported IRQ coalescing parameters a requirement.

Now that all in-tree drivers have been updated we can

Termination tables change the direction of a packet in hw from RX to SX
pipeline. Use that to offload hairpin flows received from uplink and
sent back to uplink.
Currently termination tables are used for pushing VLAN to packets
received from uplink and targeting a VF. Extend the implementation to
allow forwarding packets to uplink. These packets can either be
encapsulated or not.
In case encapsulation is needed before forwarding, move the reformat
object to the termination table as required.
Extend the hash table key to include tunnel information for the sake of
reusing reformat objects.

If udevd is configured to rename interfaces according to persistent
naming rules and if a network interface has phys_port_name in sysfs,
its contents will be appended to the interface name.
However, register_netdev creates device in sysfs and if
devlink_port_register is called after that, there is a timeframe in
which udevd may read an empty phys_port_name value. The consequence is
that the interface will lose this suffix and its name will not be
really persistent.
The solution is to register the port before registering a netdev.

Commit e687ad60af09 ("netfilter: add netfilter ingress hook after
handle_ing() under unique static key") introduced the ability to
classify packets on ingress.
Allow the same on egress. Position the hook immediately before a packet
is handed to tc and then sent out on an interface, thereby mirroring the
ingress order. This order allows marking packets in the netfilter
egress hook and subsequently using the mark in tc. Another benefit of
this order is consistency with a lot of existing documentation which
says that egress tc is performed after netfilter hooks.
Egress hooks already exist for the most common protocols, such as
NF_INET_LOCAL_OUT or NF_ARP_OUT, and those are to be preferred because
they are executed earlier during packet processing. However for more
exotic protocols, there is currently no provision to apply netfilter on
egress. A common workaround is to enslave the interface to a bridge and
use ebtables, or to resort to tc. But when the ingress hook was
introduced, consensus was that users should be given the choice to use
netfilter or tc, whichever tool suits their needs best:
https://lore.kernel.org/netdev/20150430153317.GA3230@salvia/
This hook is also useful for NAT46/NAT64, tunneling and filtering of
locally generated af_packet traffic such as dhclient.
There have also been occasional user requests for a netfilter egress
hook in the past, e.g.:
https://www.spinics.net/lists/netfilter/msg50038.html

XDP-redirect is broken in this driver sfc. XDP_REDIRECT requires
tailroom for skb_shared_info when creating an SKB based on the
redirected xdp_frame (both in cpumap and veth).
The fix requires some initial explaining. The driver uses RX page-split
when possible. It reserves the top 64 bytes in the RX-page for storing
dma_addr (struct efx_rx_page_state). It also have the XDP recommended
headroom of XDP_PACKET_HEADROOM (256 bytes). As it doesn't reserve any
tailroom, it can still fit two standard MTU (1500) frames into one page.
The sizeof struct skb_shared_info in 320 bytes. Thus drivers like ixgbe
and i40e, reduce their XDP headroom to 192 bytes, which allows them to
fit two frames with max 1536 bytes into a 4K page (192+1536+320=2048).
The fix is to reduce this drivers headroom to 128 bytes and add the 320
bytes tailroom. This account for reserved top 64 bytes in the page, and
still fit two frame in a page for normal MTUs.
We must never go below 128 bytes of headroom for XDP, as one cacheline
is for xdp_frame area and next cacheline is reserved for metadata area.

Next, represent QCOM_IPA as being dependent on QCOM_Q6V5_MSS rather
than setting its value to match QCOM_Q6V5_COMMON (which is selected
by QCOM_Q6V5_MSS).

Netlink support of extended packet number cipher suites,
allows adding and updating XPN macsec interfaces.
Added support in:
* Creating interfaces with GCM-AES-XPN-128 and GCM-AES-XPN-256 suites.
* Setting and getting 64bit packet numbers with of SAs.
* Setting (only on SA creation) and getting ssci of SAs.
* Setting salt when installing a SAK.
Added 2 cipher suite identifiers according to 802.1AE-2018 table 14-1:
* MACSEC_CIPHER_ID_GCM_AES_XPN_128
* MACSEC_CIPHER_ID_GCM_AES_XPN_256
In addition, added 2 new netlink attribute types:
* MACSEC_SA_ATTR_SSCI
* MACSEC_SA_ATTR_SALT
Depends on: macsec: Support XPN frame handling - IEEE 802.1AEbw.

Support extended packet number cipher suites (802.1AEbw) frames handling.
This does not include the needed netlink patches.
* Added xpn boolean field to `struct macsec_secy`.
* Added ssci field to `struct_macsec_tx_sa` (802.1AE figure 10-5).
* Added ssci field to `struct_macsec_rx_sa` (802.1AE figure 10-5).
* Added salt field to `struct macsec_key` (802.1AE 10.7 NOTE 1).
* Created pn_t type for easy access to lower and upper halves.
* Created salt_t type for easy access to the "ssci" and "pn" parts.
* Created `macsec_fill_iv_xpn` function to create IV in XPN mode.
* Support in PN recovery and preliminary replay check in XPN mode.
In addition, according to IEEE 802.1AEbw figure 10-5, the PN of incoming
frame can be 0 when XPN cipher suite is used, so fixed the function
`macsec_validate_skb` to fail on PN=0 only if XPN is off.
