the patch that fixed an endless loop in_fq_pie_init() was not considering
that 65535 is a valid class id. The correct bugfix for this infinite loop
is to change 'idx' to become an u32, like Colin proposed in the past [1].
Fix this as follows:
- restore 65536 as maximum possible values of 'flows_cnt'
- use u32 'idx' when iterating on 'q->flows'
- fix the TDC selftest
This reverts commit bb2f930d6dd708469a587dc9ed1efe1ef969c0bf.

The MT7628/88 SoC(s) have other (limited) packet counter registers than
currently supported in the mtk_eth_soc driver. This patch adds support
for reading these registers, so that the packet statistics are correctly
updated.
Additionally the defines for the non-MT7628 variant packet counter
registers are added and used in this patch instead of using hard coded

When TCP is used as transport and a program on the
system connects to RDS port 16385, connection is
accepted but denied per the rules of RDS. However,
RDS connections object is left in the list. Next
loopback connection will select that connection
object as it is at the head of list. The connection
attempt will hang as the connection object is set
to connect over TCP which is not allowed
The issue can be reproduced easily, use rds-ping
to ping a local IP address. After that use any
program like ncat to connect to the same IP
address and port 16385. This will hang so ctrl-c out.
Now try rds-ping, it will hang.
To fix the issue this patch adds checks to disallow
the connection object creation and destroys the

The opening comment mark '/**' is used for highlighting the beginning of
kernel-doc comments.
The header for drivers/net/ethernet/microchip/encx24j600 files follows
this syntax, but the content inside does not comply with kernel-doc.
This line was probably not meant for kernel-doc parsing, but is parsed
due to the presence of kernel-doc like comment syntax(i.e, '/**'), which
causes unexpected warning from kernel-doc.
For e.g., running scripts/kernel-doc -none
drivers/net/ethernet/microchip/encx24j600_hw.h emits:
warning: expecting prototype for h(). Prototype was for _ENCX24J600_HW_H() instead

Set the unmanaged ft flag when creating the termination table ft

In addition, set the flow that forwards to the termination table to

net/mlx5: Expose MPFS configuration API
MPFS is the multi physical function switch that bridges traffic between
the physical port and any physical functions associated with it. The
driver is required to add or remove MAC entries to properly forward
incoming traffic to the correct physical function.
We export the API to control MPFS so that other drivers, such as
mlx5_vdpa are able to add MAC addresses of their network interfaces.
The MAC address of the vdpa interface must be configured into the MPFS L2
address. Failing to do so could cause, in some NIC configurations, failure
to forward packets to the vdpa network device instance.
Fix this by adding calls to update the MPFS table.

When handling FIB_EVENT_ENTRY_REPLACE event for a new multipath route,
lag activation can be missed if a stale (struct lag_mp)->mfi pointer
exists, which was associated with an older multipath route that had been
removed.
Normally, when a route is removed, it triggers mlx5_lag_fib_event(),
which handles FIB_EVENT_ENTRY_DEL and clears mfi pointer. But, if
mlx5_lag_check_prereq() condition isn't met, for example when eswitch is
in legacy mode, the fib event is skipped and mfi pointer becomes stale.

Currently skb_checksum_help()'s return is ignored, but it may
return error when it fails to allocate memory when linearizing.
So adds checking for the return of skb_checksum_help().

Currently, when adaptive is on, the user's coalesce configuration
may be overwritten by the dynamic one. The reason is that user's
configurations are saved in struct hns3_enet_tqp_vector whose
value maybe changed by the dynamic algorithm. To fix it, use
struct hns3_nic_priv instead of struct hns3_enet_tqp_vector to
save and get the user's configuration.
BTW, operations of storing and restoring coalesce info in the reset
process are unnecessary now, so remove them as well.

In hclge_mbx_handler(), if there are two consecutive mailbox
messages that requires resp_msg, the resp_msg is not cleared
after processing the first message, which will cause the resp_msg
data of second message incorrect.
Fix it by clearing the resp_msg before processing every mailbox
message.

lan78xx already calls skb_tx_timestamp() in its lan78xx_start_xmit().
Override .get_ts_info to also advertise this capability
(SOF_TIMESTAMPING_TX_SOFTWARE) via ethtool.

This patch is to use "struct work_struct" for the finalize work queue
instead of "struct tipc_net_work", as it can get the "net" and "addr"
from tipc_net's other members and there is no need to add extra net
and addr in tipc_net by defining "struct tipc_net_work".
Note that it's safe to get net from tn->bcl as bcl is always released
after the finalize work queue is done.

We spotted a bug recently during a review where a driver was
unregistering a bus that wasn't registered, which would trigger this
BUG_ON(). Let's handle that situation more gracefully, and just print
a warning and return.
