The C codegen refers to op attribute lists all over the place,
without checking if they are present, even tho attribute list
is technically an optional property. Add them automatically
at init if missing so that we don't have to make specs longer.

setup
Recent updates to the locking mechanism that protects IPv6 routing tables
[1] have affected the SRv6 networking subsystem. Such changes cause
problems with some SRv6 Endpoints behaviors, like End.B6.Encaps and also
impact SRv6 counters.
Starting from commit 169fd62799e8 ("ipv6: Get rid of RTNL for SIOCADDRT and
RTM_NEWROUTE."), the inet6_rtm_newroute() function no longer needs to
acquire the RTNL lock for creating and configuring IPv6 routes and set up
lwtunnels.
The RTNL lock can be avoided because the ip6_route_add() function
finishes setting up a new route in a section protected by RCU.
This makes sure that no dev/nexthops can disappear during the operation.
Because of this, the steps for setting up lwtunnels - i.e., calling
lwtunnel_build_state() - are now done in a RCU lock section and not
under the RTNL lock anymore.
However, creating and configuring a lwtunnel instance in an
RCU-protected section can be problematic when that tunnel needs to
allocate memory using the GFP_KERNEL flag.
For example, the following trace shows what happens when an SRv6
End.B6.Encaps behavior is instantiated after commit 169fd62799e8 ("ipv6:
Get rid of RTNL for SIOCADDRT and RTM_NEWROUTE."):

To solve this issue, we replace the GFP_KERNEL flag with the GFP_ATOMIC
one in those SRv6 Endpoints that need to allocate memory during the
setup phase. This change makes sure that memory allocations are handled
in a way that works with RCU critical sections.

After 52358dd63e34 ("net: phy: remove function stubs") there's a
problem if CONFIG_MDIO_BUS is set, but CONFIG_PHYLIB is not.
mdiobus_scan() uses phylib functions like get_phy_device().
Bringing back the stub wouldn't make much sense, because it would
allow to compile mdiobus_scan(), but the function would be unusable.
The stub returned NULL, and we have the following in mdiobus_scan():
phydev = get_phy_device(bus, addr, c45);
if (IS_ERR(phydev))
return phydev;
So calling mdiobus_scan() w/o CONFIG_PHYLIB would cause a crash later in
mdiobus_scan(). In general the PHYLIB functionality isn't optional here.
Consequently, MDIO bus providers depend on PHYLIB.
Therefore factor it out and build it together with the libphy core
modules. In addition make all MDIO bus providers under /drivers/net/mdio
depend on PHYLIB. Same applies to enetc MDIO bus provider. Note that
PHYLIB selects MDIO_DEVRES, therefore we can omit this here.

The MediaTek MT7988 SoC comes with an single built-in Ethernet PHY for
2500Base-T/1000Base-T/100Base-TX/10Base-T link partners in addition to
the built-in 1GE switch. The built-in PHY only supports full duplex.
Add muxes allowing to select GMAC2->2.5G PHY path and add basic support
for XGMAC as the built-in 2.5G PHY is internally connected via XGMII.
The XGMAC features will also be used by 5GBase-R, 10GBase-R and USXGMII
SerDes modes which are going to be added once support for standalone PCS
drivers is in place.
In order to make use of the built-in 2.5G PHY the appropriate PHY driver
as well as (proprietary) PHY firmware has to be present as well.

In case the CMD_RTS got corrupted by interferences, the MSE102x
doesn't allow a retransmission of the command. Instead the Ethernet
frame must be shifted out of the SPI FIFO. Since the actual length is
unknown, assume the maximum possible value.

The MSE102x doesn't provide any SPI commands for interrupt handling.
So in case the interrupt fired before the driver requests the IRQ,
the interrupt will never fire again. In order to fix this always poll

When a VF is passthrough to a VM, and the VM is killed, the reported
interrupt may not been handled, it will remain, and won't be clear by
the nic engine even with a flr or tqp reset. When the VM restart, the
interrupt of the first vector may be dropped by the second enable_irq
in vfio, see the issue below:
https://gitlab.com/qemu-project/qemu/-/issues/2884#note_2423361621
We notice that the vfio has always behaved this way, and the interrupt
is a residue of the nic engine, so we fix the problem by moving the
vector enable process out of the enable_irq loop.

The VF driver missed to store the rx VLAN tag strip state when
user change the rx VLAN tag offload state. And it will default
to enable the rx vlan tag strip when re-init VF device after
reset. So if user disable rx VLAN tag offload, and trig reset,
then the HW will still strip the VLAN tag from packet nad fill
into RX BD, but the VF driver will ignore it for rx VLAN tag
offload disabled. It may cause the rx VLAN tag dropped.

When the host loses heartbeat messages from the device,
the driver calls the device-specific ndo_stop function,
which frees the resources. If the driver is unloaded in
this scenario, it calls ndo_stop again, attempting to free
resources that have already been freed, leading to a host
hang issue. To resolve this, dev_close should be called
instead of the device-specific stop function.dev_close
internally calls ndo_stop to stop the network interface
and performs additional cleanup tasks. During the driver
unload process, if the device is already down, ndo_stop
is not called.

Symptoms: NETDEV WATCHDOG: eth0 (fec): transmit queue 0 timed out
commit 37d6017b84f7 ("net: fec: Workaround for imx6sx enet tx hang when enable three queues")
There is a TDAR race condition for mutliQ when the software sets TDAR
and the UDMA clears TDAR simultaneously or in a small window (2-4 cycles).
This will cause the udma_tx and udma_tx_arbiter state machines to hang.
So, the Workaround is checking TDAR status four time, if TDAR cleared by

It is possible for a pointer of type struct inet_timewait_sock to be
returned from the functions __inet_lookup_established() and
__inet6_lookup_established(). This can cause a crash when the
returned pointer is of type struct inet_timewait_sock and
sock_put() is called on it. The following is a crash call stack that
shows sk->sk_wmem_alloc being accessed in sk_free() during the call to
sock_put() on a struct inet_timewait_sock pointer. To avoid this issue,
use sock_gen_put() instead of sock_put() when sk->sk_state
is TCP_TIME_WAIT.

This happens when copying the coredump segment list in
bnxt_hwrm_dbg_dma_data() with the HWRM_DBG_COREDUMP_LIST FW command.
The info->dest_buf buffer is allocated based on the number of coredump
segments returned by the FW. The segment list is then DMA'ed by
the FW and the length of the DMA is returned by FW. The driver then
copies this DMA'ed segment list to info->dest_buf.
In some cases, this DMA length may exceed the info->dest_buf length
and cause the above BUG condition. Fix it by capping the copy
length to not exceed the length of info->dest_buf. The extra
DMA data contains no useful information.
This code path is shared for the HWRM_DBG_COREDUMP_LIST and the
HWRM_DBG_COREDUMP_RETRIEVE FW commands. The buffering is different
for these 2 FW commands. To simplify the logic, we need to move
the line to adjust the buffer length for HWRM_DBG_COREDUMP_RETRIEVE
up, so that the new check to cap the copy length will work for both
commands.

This patch is similar to the last patch to delay the
pci_alloc_irq_vectors() call in the AER path until after calling
bnxt_reserve_rings(). bnxt_reserve_rings() needs to properly map
the MSIX table first before we call pci_alloc_irq_vectors() which
may immediately write to the MSIX table in some architectures.
Move the bnxt_init_int_mode() call from bnxt_io_slot_reset() to
bnxt_io_resume() after calling bnxt_reserve_rings().
With this change, the AER path may call bnxt_open() ->
bnxt_hwrm_if_change() with bp->irq_tbl set to NULL. bp->irq_tbl is
cleared when we call bnxt_clear_int_mode() in bnxt_io_slot_reset().
So we cannot use !bp->irq_tbl to detect aborted FW reset. Add a
new BNXT_FW_RESET_STATE_ABORT to detect aborted FW reset in
bnxt_hwrm_if_change().

On some architectures (e.g. ARM), calling pci_alloc_irq_vectors()
will immediately cause the MSIX table to be written. This will not
work if we haven't called bnxt_reserve_rings() to properly map
the MSIX table to the MSIX vectors reserved by FW.
Fix the FW error recovery path to delay the bnxt_init_int_mode() ->
pci_alloc_irq_vectors() call by removing it from bnxt_hwrm_if_change().
bnxt_request_irq() later in the code path will call it and by then the
MSIX table is properly mapped.

WARN_ON() is triggered in __flush_work() if bnxt_init_chip() fails

WARNING: CPU: 37 PID: 5223 at kernel/workqueue.c:4201 __flush_work.isra.0+0x212/0x230

Remove code that isn't reached. There is no need to check for
adapter->req_vec_chunks, because if it isn't set idpf_set_mb_vec_id()
won't be called.
Only one path when idpf_set_mb_vec_id() is called:
idpf_intr_req()
-> idpf_send_alloc_vectors_msg() -> adapter->req_vec_chunk is allocated
here, otherwise an error is returned and idpf_intr_req() exits with an
error.
The idpf_set_mb_vec_id() becomes one-liner and it is called only once.
Remove it and set mailbox vector index directly.
