0dfb2d82af net: sched: rename more stats_types
Commit 53eca1f347 ("net: rename flow_action_hw_stats_types* ->
flow_action_hw_stats*") renamed just the flow action types and
helpers. For consistency rename variables, enums, struct members
and UAPI too (note that this UAPI was not in any official release,
yet).

b723bd9339 net: stmmac: dwmac1000: Disable ACS if enhanced descs are not used
ACS (auto PAD/FCS stripping) removes FCS off 802.3 packets (LLC) so that
there is no need to manually strip it for such packets. The enhanced DMA
descriptors allow to flag LLC packets so that the receiving callback can
use that to strip FCS manually or not. On the other hand, normal
descriptors do not support that.

Thus in order to not truncate LLC packet ACS should be disabled when
using normal DMA descriptors.

458de8a97f net: page_pool: API cleanup and comments
Functions starting with __ usually indicate those which are exported,
but should not be called directly. Update some of those declared in the
API and make it more readable.

page_pool_unmap_page() and page_pool_release_page() were doing
exactly the same thing calling __page_pool_clean_page().  Let's
rename __page_pool_clean_page() to page_pool_release_page() and
export it in order to show up on perf logs and get rid of
page_pool_unmap_page().

Finally rename __page_pool_put_page() to page_pool_put_page() since we
can now directly call it from drivers and rename the existing
page_pool_put_page() to page_pool_put_full_page() since they do the same
thing but the latter is trying to sync the full DMA area.

This patch also updates netsec, mvneta and stmmac drivers which use
those functions.

It's found that stmmac_xmit() and stmmac_resume() sometimes might
run concurrently, possibly resulting in a race condition between
mod_timer() and setup_timer(), being called by stmmac_xmit() and
stmmac_resume() respectively.

Since the resume() runs setup_timer() every time, it'd be safer to
have del_timer_sync() in the suspend() as the counterpart.

bd6f48546b net: stmmac: dwmac-meson8b: Fix the RGMII TX delay on Meson8b/8m2 SoCs
GXBB and newer SoCs use the fixed FCLK_DIV2 (1GHz) clock as input for
the m250_sel clock. Meson8b and Meson8m2 use MPLL2 instead, whose rate
can be adjusted at runtime.

So far we have been running MPLL2 with ~250MHz (and the internal
m250_div with value 1), which worked enough that we could transfer data
with an TX delay of 4ns. Unfortunately there is high packet loss with
an RGMII PHY when transferring data (receiving data works fine though).
Odroid-C1's u-boot is running with a TX delay of only 2ns as well as
the internal m250_div set to 2 - no lost (TX) packets can be observed
with that setting in u-boot.

Manual testing has shown that the TX packet loss goes away when using
the following settings in Linux (the vendor kernel uses the same
settings):
- MPLL2 clock set to ~500MHz
- m250_div set to 2
- TX delay set to 2ns on the MAC side

Update the m250_div divider settings to only accept dividers greater or
equal 2 to fix the TX delay generated by the MAC.

iperf3 results before the change:
[ ID] Interval           Transfer     Bitrate         Retr
[  5]   0.00-10.00  sec   182 MBytes   153 Mbits/sec  514      sender

71a55a2315 net-next: stmmac: mediatek: add more support for RMII
MT2712 SoC can provide the rmii reference clock, and the clock
will output from TXC pin only, which means ref_clk pin of external
PHY should connect to TXC pin in this case.
Add corresponding clock and timing settings.

Down the road, devices can learn to reset just the specific queue.

The patch was generated with the following script:

use strict;
use warnings;

f421031e3f net: stmmac: reset Tx desc base address before restarting Tx
Refer to the databook of DesignWare Cores Ethernet MAC Universal:

6.2.1.5 Register 4 (Transmit Descriptor List Address Register

If this register is not changed when the ST bit is set to 0, then
the DMA takes the descriptor address where it was stopped earlier.

The stmmac_tx_err() does zero indices to Tx descriptors, but does
not reset HW current Tx descriptor address. To fix inconsistency,
the base address of the Tx descriptors should be rewritten before
restarting Tx.

d46b7e4fb0 net: phylink: rename mac_link_state() op to mac_pcs_get_state()
Rename the mac_link_state() method to mac_pcs_get_state() to make it
clear that it should be returning the MACs PCS current state, which
is used for inband negotiation rather than just reading back what the
MAC has been configured for. Update the documentation to explicitly
mention that this is for inband.

We drop the return value as well; most of phylink doesn't check the
return value and it is not clear what it should do on error - instead
arrange for state->link to be false.

c3f812cea0 page_pool: do not release pool until inflight == 0.
The page pool keeps track of the number of pages in flight, and
it isn't safe to remove the pool until all pages are returned.

Disallow removing the pool until all pages are back, so the pool
is always available for page producers.

Make the page pool responsible for its own delayed destruction
instead of relying on XDP, so the page pool can be used without
the xdp memory model.

When all pages are returned, free the pool and notify xdp if the
pool is registered with the xdp memory system.  Have the callback
perform a table walk since some drivers (cpsw) may share the pool
among multiple xdp_rxq_info.

Note that the increment of pages_state_release_cnt may result in
inflight == 0, resulting in the pool being released.

a new flag for the PTP periodic output request ioctl. This flag is not
currently supported by any driver.

Fix all drivers which implement the periodic output request ioctl to
explicitly reject any request with flags they do not understand. This
ensures that the driver does not accidentally misinterpret the
PTP_PEROUT_ONE_SHOT flag, or any new flag introduced in the future.

This is important for forward compatibility: if a new flag is
introduced, the driver should reject requests to enable the flag until
the driver has actually been modified to support the flag in question.

c2837423cb net: stmmac: Rework TX Coalesce logic
Coalesce logic currently increments the number of packets and sets the
IC bit when the coalesced packets have passed a given limit. This does
not reflect very well what coalesce was meant for as we can have a large
number of packets that are coalesced and then a single one, sent later
on that has the IC bit.

Rework the logic so that it coalesces only upon a limit of packets and
sets the IC bit for large number of packets.

Before this change of_get_phy_mode() returned an enum,
phy_interface_t. On error, -ENODEV etc, is returned. If the result of
the function is stored in a variable of type phy_interface_t, and the
compiler has decided to represent this as an unsigned int, comparision
with -ENODEV etc, is a signed vs unsigned comparision.

Fix this problem by changing the API. Make the function return an
error, or 0 on success, and pass a pointer, of type phy_interface_t,
where the phy mode should be stored.

v2:
Return with *interface set to PHY_INTERFACE_MODE_NA on error.

where the extra 4 bytes (excluding the newline) after the string
represent the integer 0x03b9aca0 = 62500000 assigned to the field
"max_adj" that follows "name" in the same struct.

There is no strict requirement for the "name" content and in the
comment in ptp_clock_kernel.h it's reported it should just be 'A
short "friendly name" to identify the clock'.
Replace it with "stmmac ptp".

7579262478 net: stmmac: add flexible PPS to dwmac 4.10a
All the registers and the functionalities used in the callback
dwmac5_flex_pps_config() are common between dwmac 4.10a [1] and
5.00a [2].

Reuse the same callback for dwmac 4.10a too.

Tested on STM32MP15x, based on dwmac 4.10a.

Add two new tests for VLAN Perfect Filtering. While at it, increase a
little bit the tests strings lenght so that we can have more descriptive
test names.

c7ab0b8088 net: stmmac: Fallback to VLAN Perfect filtering if HASH is not available
If VLAN Hash Filtering is not available we can fallback to perfect
filtering instead. Let's implement this in XGMAC and GMAC cores and let
the user use this filter.

VLAN VID=0 always passes filter so we check if more than 2 VLANs are
created and return proper error code if so because perfect filtering
only supports 1 VID at a time.

2809fc1316 net: stmmac: selftests: Fix L2 Hash Filter test
With the current MAC addresses hard-coded in the test we can get some
false positives as we use the Hash Filtering method. Let's change the
MAC addresses in the tests to be unique when hashed.

560c07cba1 net: stmmac: Support enhanced addressing mode for DWMAC 4.10
The address width of the controller can be read from hardware feature
registers much like on XGMAC. Add support for parsing the ADDR64 field
so that the DMA mask can be set accordingly.

This avoids getting swiotlb involved for DMA on Tegra186 and later.

Also make sure that the upper 32 bits of the DMA address are written to
the DMA descriptors when enhanced addressing mode is used. Similarily,
for each channel, the upper 32 bits of the DMA descriptor ring's base
address also need to be programmed to make sure the correct memory can
be fetched when the DMA descriptor ring is located beyond the 32-bit
boundary.
