mlxsw: spectrum: Teach mlxsw_sp_port_vlan_set to accept any vlan range
So far, mlxsw_sp_port_vlan_set range is limited by
MLXSW_REG_SPVM_REC_MAX_COUNT. In spectrum_switchdev code this is
wrapped up by a helper function which actually does multiple calls
to FW for bigger ranges. Move the code into mlxsw_sp_port_vlan_set

====================
net: dsa: add SMSC/Microchip LAN9303 three port ethernet switch driver
The LAN9303 is a three port 10/100 ethernet switch with integrated phys
for the two external ethernet ports. The third port is an RMII/MII
interface to a host master network interface (e.g. fixed link).
While the LAN9303 device itself supports offload packet processing, this
driver does not make use of it yet. This driver just configures the device
to provide two separate network interfaces (which is the default state of
a DSA device).
Please note: the "MDIO managed mode" driver part isn't tested yet. I have
used and tested the "I2C managed mode" only.
Changes in v6:
- fix support to use the driver as a module (core, i2c and mdio)
- license info added in all parts of the driver (for module support)
Changes in v5:
- add missing include file to 'net/dsa/tag_lan9303.c'
Changes in v4:
- rebased on net-next, 'net/dsa/tag_lan9303.c' adapted to changed API
Changes in v3:
- 'ds_to_lan9303()' removed
- special PHY reg MII_LAN911X_SPECIAL_CONTROL_STATUS mapping removed
- compatible strings for I2C and MDIO are now different
- MDIO-managed-mode devicetree binding added (still compile time tested only)
Changes in v2:
- code moved to 'drivers/net/dsa'
- timeouts in completion wait loops
- macros instead of various magic numbers
- development code removed
- devicetree property names changed
- devicetree example adapted
- tried to avoid to mix 'switching' and 'forwarding'...

DMA-API: exceeded 7 overlapping mappings of cacheline 0x01b2974d

suspend/resume or 'ifconfig' up/down. This is because DMA buffers mapped
using dma_map_single() in sh_eth_ring_format() and sh_eth_start_xmit() are
never unmapped. Resolve this problem by unmapping the buffers when freeing
the descriptor rings; in order to do it right, we'd have to add an extra

while at it).

bpf: fix checking xdp_adjust_head on tail calls
Commit
17bedab27231 ("bpf: xdp: Allow head adjustment in XDP prog")
added the xdp_adjust_head bit to the BPF prog in order to tell drivers
that the program that is to be attached requires support for the XDP
bpf_xdp_adjust_head() helper such that drivers not supporting this
helper can reject the program. There are also drivers that do support
the helper, but need to check for xdp_adjust_head bit in order to move
packet metadata prepended by the firmware away for making headroom.
For these cases, the current check for xdp_adjust_head bit is insufficient
since there can be cases where the program itself does not use the
bpf_xdp_adjust_head() helper, but tail calls into another program that
uses bpf_xdp_adjust_head(). As such, the xdp_adjust_head bit is still
set to 0. Since the first program has no control over which program it
calls into, we need to assume that bpf_xdp_adjust_head() helper is used
upon tail calls. Thus, for the very same reasons in cb_access, set the
xdp_adjust_head bit to 1 when the main program uses tail calls.

bpf: fix cb access in socket filter programs on tail calls
Commit
ff936a04e5f2 ("bpf: fix cb access in socket filter programs")
added a fix for socket filter programs such that in i) AF_PACKET the
20 bytes of skb->cb[] area gets zeroed before use in order to not leak
data, and ii) socket filter programs attached to TCP/UDP sockets need
to save/restore these 20 bytes since they are also used by protocol
layers at that time.
The problem is that bpf_prog_run_save_cb() and bpf_prog_run_clear_cb()
only look at the actual attached program to determine whether to zero
or save/restore the skb->cb[] parts. There can be cases where the
actual attached program does not access the skb->cb[], but the program
tail calls into another program which does access this area. In such
a case, the zero or save/restore is currently not performed.
Since the programs we tail call into are unknown at verification time
and can dynamically change, we need to assume that whenever the attached
program performs a tail call, that later programs could access the
skb->cb[], and therefore we need to always set cb_access to 1.

passing the packet to stack for further processing. This, however
does not make sense for the link-local packets and it loses "the
link info" once its skb->dev is changed to bonding-master. This
patch changes this behavior for link-local packets by not changing
the skb->dev to the bonding-master and maintaining it as it is,
i.e. the link on which the packet arrived.

gso: Validate assumption of frag_list segementation
Commit
07b26c9454a2 ("gso: Support partial splitting at the frag_list

one) contain the same amount of GSO payload.
This assumption is not always correct, resulting in the following
warning message in the log:
skb_segment: too many frags
For example, mlx5 driver in Striding RQ mode creates some RX SKBs with
one frag, and some with 2 frags.
After GRO, the frag_list SKBs end up having different amounts of payload.
If this frag_list SKB is then forwarded, the aforementioned assumption
is violated.
Validate the assumption, and fall back to software GSO if it not true.

This patch adds a map-in-map LRU example.
If we know only a subset of cores will use the

It allows using the common LRU map with map-update performance
comparable to the BPF_F_NO_COMMON_LRU map but without wasting memory
on the unused cores that we know they will never access the LRU map.

bpf: lru: Lower the PERCPU_NR_SCANS from 16 to 4
After doing map_perf_test with a much bigger
BPF_F_NO_COMMON_LRU map, the perf report shows a
lot of time spent in rotating the inactive list (i.e.
__bpf_lru_list_rotate_inactive):
> map_perf_test 32 8 10000
1000000 | awk '{sum += $3}END{print sum}'

> map_perf_test 32 8
10000000 10000000 | awk '{sum += $3}END{print sum}'
6283930 (6.28M/s)
By inactive, it usually means the element is not in cache. Hence,
there is a need to tune the PERCPU_NR_SCANS value.
This patch finds a better number of elements to
scan during each list rotation. The PERCPU_NR_SCANS (which
is defined the same as PERCPU_FREE_TARGET) decreases
from 16 elements to 4 elements. This change only
affects the BPF_F_NO_COMMON_LRU map.
The test_lru_dist does not show meaningful difference
between 16 and 4. Our production L4 load balancer which uses
the LRU map for conntrack-ing also shows little change in cache
hit rate. Since both benchmark and production data show no
cache-hit difference, PERCPU_NR_SCANS is lowered from 16 to 4.
We can consider making it configurable if we find a usecase
later that shows another value works better and/or use
a different rotation strategy.
After this change:

bpf: Allow bpf sample programs (*_user.c) to change bpf_map_def
The current bpf_map_def is statically defined during compile
time. This patch allows the *_user.c program to change it during
runtime. It is done by adding load_bpf_file_fixup_map() which
takes a callback. The callback will be called before creating
each map so that it has a chance to modify the bpf_map_def.
The current usecase is to change max_entries in map_perf_test.
It is interesting to test with a much bigger map size in
some cases (e.g. the following patch on bpf_lru_map.c).
However, it is hard to find one size to fit all testing
environment. Hence, it is handy to take the max_entries
as a cmdline arg and then configure the bpf_map_def during
runtime.
This patch adds two cmdline args. One is to configure
the map's max_entries. Another is to configure the max_cnt
which controls how many times a syscall is called.

-16 means -EBUSY, phy_suspend() will return -EBUSY if it finds the
device has WOL enabled.
We fix this issue by properly setting the netdev's power.can_wakeup
and power.wakeup, i.e
1. in mvneta_mdio_probe(), call device_set_wakeup_capable() to set
power.can_wakeup if the phy support WOL.
2. in mvneta_ethtool_set_wol(), call device_set_wakeup_enable() to
set power.wakeup if WOL has been successfully enabled in phy.

net: bridge: notify on hw fdb takeover
Recently we added support for SW fdbs to take over HW ones, but that
results in changing a user-visible fdb flag thus we need to send a
notification, also it's consistent with how HW takes over SW entries.

====================
mediatek: Fix crash caused by reporting inconsistent skb->len to BQL
Changes since v1:
- fix inconsistent enumeration which easily causes the potential bug
The series fixes kernel BUG caused by inconsistent SKB length reported
into BQL. The reason for inconsistent length comes from hardware BUG which
results in different port number carried on the TXD within the lifecycle of
SKB. So patch 2) is proposed for use a software way to track which port
the SKB involving instead of hardware way. And patch 1) is given for another
issue I found which causes TXD and SKB inconsistency that is not expected
in the initial logic, so it is also being corrected it in the series.
The log for the kernel BUG caused by the issue is posted as below.
