9c9211a3fc net_tstamp: add new flag HWTSTAMP_FLAG_BONDED_PHC_INDEX
Since commit 94dd016ae5 ("bond: pass get_ts_info and SIOC[SG]HWTSTAMP
ioctl to active device") the user could get bond active interface's
PHC index directly. But when there is a failover, the bond active
interface will change, thus the PHC index is also changed. This may
break the user's program if they did not update the PHC timely.

This patch adds a new hwtstamp_config flag HWTSTAMP_FLAG_BONDED_PHC_INDEX.
When the user wants to get the bond active interface's PHC, they need to
add this flag and be aware the PHC index may be changed.

With the new flag. All flag checks in current drivers are removed. Only
the checking in net_hwtstamp_validate() is kept.

c8064e5b4a bpf: Let bpf_warn_invalid_xdp_action() report more info
In non trivial scenarios, the action id alone is not sufficient to
identify the program causing the warning. Before the previous patch,
the generated stack-trace pointed out at least the involved device
driver.

Let's additionally include the program name and id, and the relevant
device name.

If the user needs additional infos, he can fetch them via a kernel
probe, leveraging the arguments added here.

8581fd402a treewide: Add missing includes masked by cgroup -> bpf dependency
cgroup.h (therefore swap.h, therefore half of the universe)
includes bpf.h which in turn includes module.h and slab.h.
Since we're about to get rid of that dependency we need
to clean things up.

v2: drop the cpu.h include from cacheinfo.h, it's not necessary
and it makes riscv sensitive to ordering of include files.

0e9e7598c6 octeontx2-nic: fix mixed module build
Building the VF and PF side of this driver differently, with one being
a loadable module and the other one built-in results in a link failure
for the common PTP driver:

ld.lld: error: undefined symbol: __this_module
>>> referenced by otx2_ptp.c
>>>               net/ethernet/marvell/octeontx2/nic/otx2_ptp.o:(otx2_ptp_init) in archive drivers/built-in.a
>>> referenced by otx2_ptp.c
>>>               net/ethernet/marvell/octeontx2/nic/otx2_ptp.o:(otx2_ptp_init) in archive drivers/built-in.a

Move the otx2_ptp.c code into a separate module that gets built for
both configurations, making it built-in if at least one of the other
two is built-in.

0182d0788c octeontx2-pf: Simplify the receive buffer size calculation
This patch separates the logic of configuring hardware
maximum transmit frame size and receive frame size.
This simplifies the logic to calculate receive buffer
size and using cqe descriptor of different size.
Also additional size of skb_shared_info structure is
allocated for each receive buffer pointer given to
hardware which is not necessary. Hence change the
size calculation to remove the size of
skb_shared_info. Add a check for array out of
bounds while adding fragments to the network stack.

Current driver uses software CQ head pointer to poll on CQE
header in memory to determine if CQE is valid. Software needs
to make sure, that the reads of the CQE do not get re-ordered
so much that it ends up with an inconsistent view of the CQE.
To ensure that DMB barrier after read to first CQE cacheline
and before reading of the rest of the CQE is needed.
But having barrier for every CQE read will impact the performance,
instead use hardware CQ head and tail pointers to find the
valid number of CQEs.

99bbc4ae69 octeontx2-af: Add external ptp input clock
PTP hardware block can be configured to utilize
the external clock. Also the current ptp timestamp
can be captured when external trigger is applied on
a gpio pin. These features are required in scenarios
like connecting a external timing device to the chip
for time synchronization. The timing device provides
the clock and trigger(PPS signal) to the PTP block.
This patch does the following:
1. configures PTP block to use external clock
frequency and timestamp capture on external event.
2. sends PTP_REQ_EXTTS events to kernel ptp phc susbsytem
with captured timestamps
3. aligns PPS edge to adjusted ptp clock in the ptp device
by setting the PPS_THRESH to the reminder of the last
timestamp value captured by external PPS

ef6c8da71e octeontx2-pf: cn10K: Reserve LMTST lines per core
This patch reserves the LMTST lines per cpu instead
of separate LMTST lines for NPA(buffer free) and NIX(sqe flush).
LMTST line of the core on which SQ or RQ is processed is used
for LMTST operation.

This patch also replace STEOR with STEORL release semantics and
updates driver name in ethtool file.

NPC extraction profile marks layer types
NPC_LT_LB_CTAG for CTAG and NPC_LT_LB_STAG_QINQ for
STAG after parsing input packet. Those layer types
can be used to install ntuple filters using
vlan-etype option. Below are the commands and
corresponding behavior with this patch in place.

> alias nt "ethtool -U eth0 flow-type ether"

> nt vlan 5 m 0xf000 action 0
Input packets with outer VLAN id as 5 i.e,
stag packets with VLAN id 5 and ctag packets with
VLAN id as 5 are hit.

> nt vlan-etype 0x8100 action 0
All input ctag packets with any VLAN id are hit.

> nt vlan-etype 0x88A8 action 0
All input stag packets with any VLAN id are hit.

> nt vlan-etype 0x8100 vlan 5 m 0xf000 action 0
All input ctag packets with VLAN id 5 are hit.

> nt vlan-etype 0x88A8 vlan 5 m 0xf000 action 0
All input stag packets with VLAN id 5 are hit.

05209e3570 octeontx2-pf: Don't install VLAN offload rule if netdev is down
Whenever user changes interface MAC address both default DMAC based
MCAM rule and VLAN offload (for strip) rules are updated with new
MAC address. To update or install VLAN offload rule PF driver needs
interface's receive channel info, which is retrieved from admin
function at the time of NIXLF initialization.

If user changes MAC address before interface is UP, VLAN offload rule
installation will fail and throw error as receive channel is not valid.
To avoid this, skip VLAN offload rule installation if netdev is not UP.
This rule will anyway be reinslatted as part of open() call.

a76053707d dev_ioctl: split out ndo_eth_ioctl
Most users of ndo_do_ioctl are ethernet drivers that implement
the MII commands SIOCGMIIPHY/SIOCGMIIREG/SIOCSMIIREG, or hardware
timestamping with SIOCSHWTSTAMP/SIOCGHWTSTAMP.

Separate these from the few drivers that use ndo_do_ioctl to
implement SIOCBOND, SIOCBR and SIOCWANDEV commands.

This is a purely cosmetic change intended to help readers find
their way through the implementation.

69f0aeb13b octeontx2-pf: Fix interface down flag on error
In the existing code while changing the number of TX/RX
queues using ethtool the PF/VF interface resources are
freed and reallocated (otx2_stop and otx2_open is called)
if the device is in running state. If any resource allocation
fails in otx2_open, driver free already allocated resources
and return. But again, when the number of queues changes
as the device state still running oxt2_stop is called.
In which we try to free already freed resources leading
to driver crash.
This patch fixes the issue by setting the INTF_DOWN flag on
error and free the resources in otx2_stop only if the flag is
not set.
