TX FIFO size is 32k and it was divided into 256 pages with 128 bytes.
A boundary is used to split pages into two parts, head part is used to
store TX packets coming from host, and tail part is reserved for special
purposes, such as beacon packet, null data packet and so on.
The TX packets coming from host have many categories, such as VO, VI, BE,
BK, MG and etc. When going into head part of TX FIFO, they are classified
to four priority queue named low, normal, high and extra priority queues.
Each priority queue occupies predefined number of page, if a certain
priority queue is full, TX packet will store into PUB priority queue.
Similarly, RX FIFO is 16k and split into two parts, head part is used to
store RX packets, and tail part is 128 bytes and used to store report.
Thus, we fill this boundary to register as well.

The power polling command is one kind of power sequence commands. It's used
to check hardware situation, and subsequent comamnds will be executed if
hardware is ready. A special case is PCIE must toggle BIT_PFM_WOWL and try
again if first try is failed.
In order to reduce indentation to understand the code easier, move polling
part to a separate function. Then, the 'while (1)...loop' is replaced by
two statements to do first try and retry.

The mac power-on flow consists of three steps:
1. pre_sys_cfg (Before switching power state)
2. power_switch (Switching power state)
3. init_sys_cfg (Settings after swtiching power state)
When switching power state, driver will load and parse the power sequence
tables. For 8723D devices, the logics for parsing are most same except for
the polling function. 8723D devices need to toggle BIT_PFM_WOWL twice.
The settings after power state is switched for 8723D devices are quite
different with other devices, extract a legacy function for them.
For power-off flow, 8723D devices have the same logic with existing chips.
But warning printed if we run power-off sequence in power-off state:
rtw_pci 0000:03:00.0: failed to poll offset=0x5f8 mask=0xff value=0x0
The scenario is user do 'ifconfig up' that will run power-on sequence to
bring up and then run power-off sequence to enter idle
(IEEE80211_CONF_IDLE). Then, user do 'ifconfig down' that will run
power-off sequence again, and the warning is shown. Original code check
power-on state to avoid to run power-on sequence twice, and this commit
extends to check both power-on and power-off states.

dpaa2-eth: add support for xdp bulk enqueue
The first patch moves the DEV_MAP_BULK_SIZE macro into the xdp.h header
file so that drivers can take advantage of it and use it.
The following 3 patches are there to setup the scene for using the bulk
enqueue feature. First of all, the prototype of the enqueue function is
changed so that it returns the number of enqueued frames. Second, the
bulk enqueue interface is used but without any functional changes, still
one frame at a time is enqueued. Third, the .ndo_xdp_xmit callback is
split into two stages, create all FDs for the xdp_frames received and
then enqueue them.
The last patch of the series builds on top of the others and instead of
issuing an enqueue operation for each FD it issues a bulk enqueue call
for as many frames as possible. This is repeated until all frames are
enqueued or the maximum number of retries is hit. We do not use the
XDP_XMIT_FLUSH flag since the architecture is not capable to store all
frames dequeued in a NAPI cycle, instead we send out right away all
frames received in a .ndo_xdp_xmit call.
Changes in v2:
- statically allocate an array of dpaa2_fd by frame queue
- use the DEV_MAP_BULK_SIZE as the maximum number of xdp_frames
received in .ndo_xdp_xmit()

Take advantage of the bulk enqueue feature in .ndo_xdp_xmit.
We cannot use the XDP_XMIT_FLUSH since the architecture is not capable
to store all the frames dequeued in a NAPI cycle so we instead are
enqueueing all the frames received in a ndo_xdp_xmit call right away.

frames at a time until all are sent or the maximum number of retries is

Add the dpaa2_eth_xdp_create_fd that just transforms an xdp_frame into a

each frame.

The data fin flag is set only via a DSS option, but
mptcp_incoming_options() copies it unconditionally from the
provided RX options.
Since we do not clear all the mptcp sock RX options in a
socket free/alloc cycle, we can end-up with a stray data_fin
value while parsing e.g. MPC packets.
That would lead to mapping data corruption and will trigger
a few WARN_ON() in the RX path.
Instead of adding a costly memset(), fetch the data_fin flag
only for DSS packets - when we always explicitly initialize
such bit at option parsing time.

reset-gpios = <&gpio5 9 GPIO_ACTIVE_LOW>;

Add support for following phy-modes: rgmii, rgmii-id, rgmii-txid, rgmii-rxid.
This PHY has an internal RX delay of 1.2ns and no delay for TX.
The pad skew registers allow to set the total TX delay to max 1.38ns and
the total RX delay to max of 2.58ns (configurable 1.38ns + build in
1.2ns) and a minimal delay of 0ns.
According to the RGMII v1.3 specification the delay provided by PCB traces
should be between 1.5ns and 2.0ns. The RGMII v2.0 allows to provide this
delay by MAC or PHY. So, we configure this PHY to the best values we can
get by this HW: TX delay to 1.38ns (max supported value) and RX delay to
1.80ns (best calculated delay)
The phy-modes can still be fine tuned/overwritten by *-skew-ps

and we've closed our one-to-one socket, while the peer crashes without
being detected, restarts and reconnects using the same addresses and
ports, we start association shutdown.
In this case, Cumulative TSN Ack in the SHUTDOWN that we send has

When we start shutdown in sctp_sf_do_dupcook_a(), we want to bundle

commit 4ff40b8626 ("sctp: set chunk transport correctly when it's a

the SHUTDOWN.
Fix this by passing a reference to the COOKIE-ACK chunk as an argument
to sctp_sf_do_9_2_start_shutdown() and onward to
sctp_make_shutdown(). This way the SHUTDOWN chunk is assigned the same
transport as the COOKIE-ACK chunk, which allows them to be bundled.
In sctp_sf_do_9_2_start_shutdown(), the void *arg parameter was
previously unused. Now that we're taking it into use, it must be a
valid pointer to a chunk, or NULL. There is only one call site where
it's not, in sctp_sf_autoclose_timer_expire(). Fix that too.

Right now it can be seen that the VSC9959 (Felix) switch will not flood
frames if they have a VLAN tag with a PCP of 1-7 (nonzero).
It turns out that Felix is quite different from its cousin, Ocelot, in
that frame flooding can be allowed/denied per traffic class. Where
Ocelot has 1 instance of the ANA_FLOODING register, Felix has 8.
The approach that this driver is going to take is "thanks, but no
thanks". We have no use case of limiting the flooding domain based on
traffic class, so we just want to allow packets to be flooded, no matter
what traffic class they have.
So we copy the line of code from ocelot.c which does the one-shot
initialization of the flooding PGIDs, and we add it to felix.c as well -
except replicated 8 times.
