There is asymmetry in how the VXLAN join and leave functions are used.
The join function (mlxsw_sp_bridge_vxlan_join()) is only called in
response to netdev events (e.g., VXLAN device joining a bridge), but the
leave function is also called in response to switchdev events (e.g.,
VLAN configuration on top of the VXLAN device) in order to invalidate
VNI to FID mappings.
This asymmetry will cause problems when the functions will be later
extended to mark VXLAN bridge ports as offloaded or not.
Therefore, create an internal function (__mlxsw_sp_bridge_vxlan_leave())
that is used to invalidate VNI to FID mappings and call it from
mlxsw_sp_bridge_vxlan_leave() which will only be invoked in response to
netdev events, like mlxsw_sp_bridge_vxlan_join().
No functional changes intended.

bridge
mlxsw_sp_bridge_vxlan_{join,leave}() are not called when a VXLAN device
joins or leaves a VLAN-aware bridge. As mentioned in the comment - when the
bridge is VLAN-aware, the VNI of the VXLAN device needs to be mapped to a
VLAN, but at this point no VLANs are configured on the VxLAN device. This
means that we can call the APIs, but there is no point to do that, as they
do not configure anything in such cases.
Next patch will extend mlxsw_sp_bridge_vxlan_{join,leave}() to set hardware
domain for VXLAN, this should be done also when a VXLAN device joins or
leaves a VLAN-aware bridge. Call the APIs, which for now do not do anything
in these flows.
Align the call to mlxsw_sp_bridge_vxlan_leave() to be called like
mlxsw_sp_bridge_vxlan_join(), only in case that the VXLAN device is up,
so move the check to be done before calling
mlxsw_sp_bridge_vxlan_{join,leave}(). This does not change the existing
behavior, as there is a similar check inside mlxsw_sp_bridge_vxlan_leave().

Next patch will set the same hardware domain for all bridge ports,
including VXLAN, to prevent packets from being forwarded by software when
they were already forwarded by hardware.
ARP packets are not flooded by hardware to VXLAN, so software should handle
such flooding. When hardware domain of VXLAN device will be changed, ARP
packets which are trapped and marked with offload_fwd_mark will not be
flooded to VXLAN also in software, which will break VXLAN traffic.
To prevent such breaking, trap ARP packets at layer 2 and don't mark them
as L2-forwarded in hardware, then flooding ARP packets will be done only
in software, and VXLAN will send ARP packets.
Remove NVE_ENCAP_ARP which is no longer needed, as now ARP packets are
trapped when they enter the device.

The bd_cnt field in the TX BD specifies the total number of BDs for
the TX packet. The bd_cnt field has 5 bits and the maximum number
supported is 32 with the value 0.
CONFIG_MAX_SKB_FRAGS can be modified and the total number of SKB
fragments can approach or exceed the maximum supported by the chip.
Add a macro to properly mask the bd_cnt field so that the value 32
will be properly masked and set to 0 in the bd_cnd field.
Without this patch, the out-of-range bd_cnt value will corrupt the
TX BD and may cause TX timeout.
The next patch will check for values exceeding 32.

The net fixed phy driver does not require the creation of a platform
device. Originally, this approach was chosen for simplicity when the
driver was first implemented.
With the introduction of the lightweight faux device interface, we now
have a more appropriate alternative. Migrate the device to utilize the
faux bus, given that the platform device it previously created was not
a real one anyway. This will get rid of the fake platform device.

There commands can be used to add an RSS context and steer some traffic
into it:
# ethtool -X eth0 context new
New RSS context is 1
# ethtool -N eth0 flow-type ip4 dst-ip 1.1.1.1 context 1
Added rule with ID 1023
However, the second command fails with EINVAL on mlx5e:
# ethtool -N eth0 flow-type ip4 dst-ip 1.1.1.1 context 1
rmgr: Cannot insert RX class rule: Invalid argument
Cannot insert classification rule
It happens when flow_get_tirn calls flow_type_to_traffic_type with
flow_type = IP_USER_FLOW or IPV6_USER_FLOW. That function only handles
IPV4_FLOW and IPV6_FLOW cases, but unlike all other cases which are
common for hash and spec, IPv4 and IPv6 defines different contants for
hash and for spec:
#define TCP_V4_FLOW 0x01 /* hash or spec (tcp_ip4_spec) */
#define UDP_V4_FLOW 0x02 /* hash or spec (udp_ip4_spec) */
...
#define IPV4_USER_FLOW 0x0d /* spec only (usr_ip4_spec) */
#define IP_USER_FLOW IPV4_USER_FLOW
#define IPV6_USER_FLOW 0x0e /* spec only (usr_ip6_spec; nfc only) */
#define IPV4_FLOW 0x10 /* hash only */
#define IPV6_FLOW 0x11 /* hash only */
Extend the switch in flow_type_to_traffic_type to support both, which
fixes the failing ethtool -N command with flow-type ip4 or ip6.

Commit 809265fe96fe ("net: phy: c45: remove local advertisement
parameter from genphy_c45_eee_is_active") stopped reading the local
advertisement from the PHY earlier in this development cycle, which
broke "ethtool --set-eee ethX eee off".
When ethtool is used to set EEE off, genphy_c45_eee_is_active()
indicates that EEE was active if the link partner reported an
advertisement, which causes phylib to set phydev->enable_tx_lpi on
link up, despite our local advertisement in hardware being empty.
However, phydev->advertising_eee is preserved while EEE is turned off,
which leads to genphy_c45_eee_is_active() incorrectly reporting that
EEE is active.
Fix it by checking phydev->eee_cfg.eee_enabled, and if clear,
immediately indicate that EEE is not active.

The code was incorrectly relying on PCAM bit of ppcnt_statistical_group
for accessing per_lane_error_counters.
If ppcnt_statistical_group PCAM bit was not set, we would not read
per_lane_error_counters, even when its PCAM bit is set.
Given the existing device capabilities, it seems to cause no harm, so
this change primarily serves as cleanup.

This commit appends a common "sysdata" suffix to functions responsible
for appending data to sysdata.
This change enhances code clarity and prevents naming conflicts with
other "append" functions, particularly in anticipation of the upcoming

This one is hilariously outdated, it provided a faster downlink over
TV cable for users of analog modems in the 1990s, through an ISA card.
The web page for the userspace tools has been broken for 25 years, and
the driver has only ever seen mechanical updates.

N_TTY_BUF_SIZE -- as the name suggests -- is the N_TTY's buffer size.
There is no reason to couple that to caif's tty->receive_room. Use 4096
directly -- even though, it should be some sort of "SKB_MAX_ALLOC" or
alike. But definitely not N_TTY_BUF_SIZE.
N_TTY_BUF_SIZE is private and will be moved to n_tty.c later.
