The process is similar to that of the ADD_ADDR IPv6, this patch also sent
out a pure ack for the ADD_ADDR using port.

This patch added a new add_addr_signal type named MPTCP_ADD_ADDR_PORT,
to identify it is an address with port to be added.
It also added a new parameter 'port' for both mptcp_add_addr_len and
mptcp_pm_add_addr_signal.
In mptcp_established_options_add_addr, we check whether the announced
address is added with port. If it is, we put this port number to
mptcp_out_options's port field.

This patch uses adding up size to get the ADD_ADDR suboption length rather

In rfc8684, the length of ADD_ADDR suboption with IPv4 address and port
is 18 octets, but mptcp_write_options is 32-bit aligned, so we need to
pad it to 20 octets. All the other port related option lengths need to
be added up 2 octets similarly.
This patch added a new field 'port' in mptcp_out_options. When this
field is set with a port number, we need to add up 4 octets for the
ADD_ADDR suboption, and put the port number into the suboption.

The length of ADD_ADDR6 is 12 octets longer than ADD_ADDR. That's the
only difference between them.
This patch dropped the duplicate code between ADD_ADDR and ADD_ADDR6

There are two differences between ADD_ADDR suboption and ADD_ADDR echo
suboption: The length of the former is 8 octets longer than the length
of the latter. The former's echo-flag is 0, and latter's echo-flag is 1.
This patch added two local variables, len and echo, to unify ADD_ADDR
and ADD_ADDR echo suboptions writing.

100GbE Intel Wired LAN Driver Updates 2020-12-09
This series contains updates to ice driver only.
Bruce changes the allocation of ice_flow_prof_params from stack to heap to
avoid excessive stack usage. Corrects a misleading comment and silences a
sparse warning that is not a problem.
Paul allows for HW initialization to continue if PHY abilities cannot
be obtained.
Jeb removes bypassing FW link override and reading Option ROM and
netlist information for non-E810 devices as this is now available on
other devices.
Nick removes vlan_ena field as this information can be gathered by
checking num_vlan.
Jake combines format strings and debug prints to the same line.
Simon adds a space to fix string concatenation.
v4: Drop ACL patches. Change PHY abilities failure message from debug to
warning.
v3: Fix email address for DaveM and fix character in cover letter
v2: Expand on commit message for patch 3 to show example usage/commands.

For stable Samsung's I2C interrupt handling, I changed the interrupt

Change interrupt trigger from IRQ_TYPE_LEVEL_HIGH to IRQ_TYPE_EDGE_RISING
for stable NFC I2C interrupt handling.
Samsung's NFC Firmware sends an i2c frame as below.
1. NFC Firmware sets the GPIO(interrupt pin) high when there is an i2c
frame to send.
2. If the CPU's I2C master has received the i2c frame, NFC F/W sets the
GPIO low.
NFC driver's i2c interrupt handler would be called in the abnormal case
as the NFC FW task of number 2 is delayed because of other high priority
tasks.
In that case, NFC driver will try to receive the i2c frame but there isn't
any i2c frame to send in NFC.
It would cause an I2C communication problem. This case would hardly happen.
But, I changed the interrupt as a defense code.
If Driver uses the TRIGGER_RISING instead of the LEVEL trigger,
there would be no problem even if the NFC FW task is delayed.

SAMA7G5's ethernet IPs TX clock could be provided by its generic clock or
by the external clock provided by the PHY. The internal IP logic divides
properly this clock depending on the link speed. The patch adds a new
capability so that macb_set_tx_clock() to not be called for IPs having
this capability (the clock rate, in case of generic clock, is set at the
boot time via device tree and the driver only enables it).

This patch implements the ndo_xdp_xmit() net_device function which is
called when a packet is redirected to this driver using an
XDP_REDIRECT directive.
The function receives an array of xdp frames that it needs to xmit.
The TX queues that are used to xmit these frames are the XDP
queues used by the XDP_TX flow. Therefore a lock is added to synchronize
both flows (XDP_TX and XDP_REDIRECT).

XDP subsystem has a function to free XDP frames and their associated

introduction of XDP MB).
Also, remove 'xdp_rx_page' field from ena_tx_buffer struct since it is

This patch adds a partial support for the XDP_REDIRECT directive which
instructs the driver to pass the packet to an interface specified by the
program. The directive is passed to the driver by calling bpf_redirect()
or bpf_redirect_map() functions from the eBPF program.
To lay the ground for integration with the existing XDP TX
implementation the patch removes the redundant page ref count increase
in ena_xdp_xmit_frame() and then decrease in ena_clean_rx_irq(). Instead
it only DMA unmaps descriptors for which XDP TX or REDIRECT directive
was received.
The XDP Redirect support is still missing .ndo_xdp_xmit function
implementation, which allows to redirect packet to an ENA interface,
which would be added in a later patch.

Introduce ena_increase_stat() function to increase statistics by a
certain number.
The function includes the
- lock aquire (on 32bit machines)
- stat increase
- lock release (on 32bit machines)
line sequence that is ubiquitous across the driver.
The function increases a single stat at a time and several stats which
are increased together weren't put into a function to avoid
calling the function several times for each stat which looks bad and
might decrease performance.

ENA logs are adjusted to display the full ENA representation to
distinct each ENA device in case of multiple interfaces.
Using netdev_err/warn and dev_info functions for logging provides
uniform printing with clear distinction of the device and interface.
This patch changes all printing in ena_com files to use netev_* logging
functions except for messages of info level. Log functions of that level
would be printed with dev_info because of the early stage they are
called in when net_device struct isn't yet registered.
To allow using netdev_* functions in all ena_com functions, a pointer to
the net_device was added to ena_com_dev struct.
The patch also adds some log messages to make driver debugging easier.

The patch changes the maximum number of RX/TX queues it advertises to
the kernel (via alloc_etherdev_mq()) from a value received from the
device to a constant value which is the minimum between 128 and the
number of CPUs in the system.
By allocating the net_device struct with a constant number of queues,
the driver is able to allocate it at a much earlier stage, before
calling any ena_com functions. This would allow to make all log prints
in ena_com to use netdev_* log functions instead or current pr_* ones.
Note:
netdev_* prints in ena_com functions that are called before
net_device registration in ena_probe() might print messages that are
a bit ugly (with strings like "(unnamed net_device) (uninitialized)").
However we decided to use netdev_* prints in these functions anyway,
for the sake of getting better messages later, when ena_com functions
are called after ena_probe() form other parts of the driver.
See discussion about this decision in [1].
