The SMMU engine on HIP09 chip has a hardware issue.
SMMU pagetable prefetch features may prefetch and use a invalid PTE
even the PTE is valid at that time. This will cause the device trigger
fake pagefaults. The solution is to avoid prefetching by adding a
SYNC command when smmu mapping a iova. But the performance of nic has a
sharp drop. Then we do this workaround, always enable tx bounce buffer,
avoid mapping/unmapping on TX path.
This issue only affects HNS3, so we always enable
tx bounce buffer when smmu enabled to improve performance.

Currently, the driver uses phylib to operate PHY by default.
On some boards, the PHY device is separated from the MAC device.
As a result, the hibmcge driver cannot operate the PHY device.
In this patch, the driver determines whether a PHY is available
based on register configuration. If no PHY is available,
the driver will use fixed_phy to register fake phydev.

If the driver reset fails, it may not work properly.
Therefore, the ndo.open() operation should be rejected.
In this patch, the driver calls netif_device_detach()
before the reset and calls netif_device_attach()
after the reset succeeds. If the reset fails,
netif_device_attach() is not called. Therefore,
netdev does not present and cannot be opened.
If reset fails, only the PCI reset (via sysfs)
can be used to attempt recovery.

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.

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.

This patch adds the rtnl_lock to hbg_fix_np_link_fail()
to ensure that other operations are not performed concurrently.
In addition, np_link_fail exception can be fixed
only when the PHY is link.

The MAC hardware supports receiving two types of
pause frames from link partner.
One is a pause frame with a destination address
of 01:80:C2:00:00:01.
The other is a pause frame whose destination address
is the address of the hibmcge driver.
01:80:C2:00:00:01 is supported by default.
In .ndo_set_mac_address(), the hibmcge driver calls
.hbg_hw_set_rx_pause_mac_addr() to set its mac address as the
destination address of the rx puase frame.
Therefore, pause frames with two types of MAC addresses can be received.
Currently, the rx pause addr does not restored after reset.
As a result, pause frames whose destination address is
the hibmcge driver address cannot be correctly received.
This patch restores the configuration by calling
.hbg_hw_set_rx_pause_mac_addr() after reset is complete.

In the debugfs file, the driver displays the np_link fail state
based on the HBG_NIC_STATE_NP_LINK_FAIL.
However, HBG_NIC_STATE_NP_LINK_FAIL is cleared in hbg_service_task()
So, this value of np_link fail is always false.
This patch directly reads the related register to display the real state.

A dbg log is generated when the driver modifies the MTU,
which is expected to trace the change of the MTU.
However, the log is recorded after WRITE_ONCE().
At this time, netdev->mtu has been changed to the new value.
As a result, netdev->mtu is the same as new_mtu.
This patch modifies the log location and records logs before WRITE_ONCE().

issue
hbg_irqs is a global array which contains irq statistics.
However, the irq statistics of different network ports
point to the same global array. As a result, the statistics are incorrect.
This patch allocates a statistics array for each network port
to prevent the statistics of different network ports
from affecting each other.
irq statistics are removed from hbg_irq_info. Therefore,
all data in hbg_irq_info remains unchanged. Therefore,
the input parameter of some functions is changed to const.

The driver supports pause frames,
but does not pass pause frames based on rx pause enable configuration,
resulting in incorrect pause frame statistics.
like this:
mz eno3 '01 80 c2 00 00 01 00 18 2d 04 00 9c 88 08 00 01 ff ff' \
-p 64 -c 100
ethtool -S enp132s0f2 | grep -v ": 0"
NIC statistics:
rx_octets_total_filt_cnt: 6800
rx_filt_pkt_cnt: 100
The rx pause frames are filtered by the MAC hardware.
This patch configures pass pause frames based on the
rx puase enable status to ensure that
rx pause frames are not filtered.

Pull networking updates from Jakub Kicinski:
"Core & protocols:
- Continue Netlink conversions to per-namespace RTNL lock
(IPv4 routing, routing rules, routing next hops, ARP ioctls)
- Continue extending the use of netdev instance locks. As a driver
opt-in protect queue operations and (in due course) ethtool
operations with the instance lock and not RTNL lock.
- Support collecting TCP timestamps (data submitted, sent, acked) in
BPF, allowing for transparent (to the application) and lower
overhead tracking of TCP RPC performance.
- Tweak existing networking Rx zero-copy infra to support zero-copy
Rx via io_uring.
- Optimize MPTCP performance in single subflow mode by 29%.
- Enable GRO on packets which went thru XDP CPU redirect (were queued
for processing on a different CPU). Improving TCP stream
performance up to 2x.
- Improve performance of contended connect() by 200% by searching for
an available 4-tuple under RCU rather than a spin lock. Bring an
additional 229% improvement by tweaking hash distribution.
- Avoid unconditionally touching sk_tsflags on RX, improving
performance under UDP flood by as much as 10%.
- Avoid skb_clone() dance in ping_rcv() to improve performance under
ping flood.
- Avoid FIB lookup in netfilter if socket is available, 20% perf win.
- Rework network device creation (in-kernel) API to more clearly
identify network namespaces and their roles. There are up to 4
namespace roles but we used to have just 2 netns pointer arguments,
interpreted differently based on context.
- Use sysfs_break_active_protection() instead of trylock to avoid
deadlocks between unregistering objects and sysfs access.
- Add a new sysctl and sockopt for capping max retransmit timeout in
TCP.
- Support masking port and DSCP in routing rule matches.
- Support dumping IPv4 multicast addresses with RTM_GETMULTICAST.
- Support specifying at what time packet should be sent on AF_XDP
sockets.
- Expose TCP ULP diagnostic info (for TLS and MPTCP) to non-admin
users.
- Add Netlink YAML spec for WiFi (nl80211) and conntrack.
- Introduce EXPORT_IPV6_MOD() and EXPORT_IPV6_MOD_GPL() for symbols
which only need to be exported when IPv6 support is built as a
module.

normal bridging.

messages as metadata

Pull timer cleanups from Thomas Gleixner:
"A treewide hrtimer timer cleanup
hrtimers are initialized with hrtimer_init() and a subsequent store to
the callback pointer. This turned out to be suboptimal for the
upcoming Rust integration and is obviously a silly implementation to
begin with.
This cleanup replaces the hrtimer_init(T); T->function = cb; sequence
with hrtimer_setup(T, cb);
The conversion was done with Coccinelle and a few manual fixups.
Once the conversion has completely landed in mainline, hrtimer_init()
will be removed and the hrtimer::function becomes a private member"

phy_loopback() leaves it to the PHY driver to select the speed of the
loopback mode. Thus, the speed of the loopback mode depends on the PHY
driver in use.
Add support for speed selection to phy_loopback() to enable loopback
with defined speeds. Ensure that link up is signaled if speed changes
as speed is not allowed to change during link up. Link down and up is
necessary for a new speed.
