===================
lan78xx NAPI Performance Improvements
This patch set introduces a set of changes to the lan78xx driver
that were originally developed as part of an investigation into
the performance of TCP and UDP transfers on an Android system.
The changes increase the throughput of both UDP and TCP transfers
and reduce the overall CPU load.
These improvements are also seen on a standard Linux kernel. Typical
results are included at the end of this document.
The changes to the driver evolved over time. The patches presented
here attempt to organise the changes in to coherent blocks that
affect logically connected parts of the driver. The patches do not
reflect the way in which the code evolved during the performance
investigation.
Each patch produces a working driver that has an incremental
improvement but patches 2, 3 and 6 should be considered a single
update.
The changes affect the following parts of the driver:
1. Deferred URB processing
The deferred URB processing that was originally done by a tasklet
is now done by a NAPI polling routine. The NAPI cycle has a fixed
work budget that controls how many received frames are passed to
the network stack.
Patch 6 introduces the NAPI polling but depends on preceding patches.
The new NAPI polling routine is also responsible for submitting
Rx and Tx URBs to the USB host controller.
Moving the URB processing to a NAPI-based system "smoothed"
incoming and outgoing data flows on the Android system under
investigation. However, taken in isolation, moving from a tasklet
approach to a NAPI approach made little or no difference to the
overall performance.
2. URB buffer management
The driver creates a pool of Tx and a pool of Rx URB buffers. Each
buffer is large enough to accommodate a packet with the maximum MTU
data. URBs are allocated from these pools as required.
Patch 2 introduces the new Tx buffer pool.
Patch 3 introduces the new Rx buffer pool.
3. Tx pending data
SKBs containing data to be transmitted are added to a queue. The
driver tracks free Tx URBs and the corresponding free Tx URB space.
When new Tx URBs are submitted, pending data is copied into the
URB buffer until the URB buffer is filled or there is no more
pending data. This maximises utilisation the LAN78xx internal
USB and network frame buffers.
New Tx URBs are submitted to the USB host controller as part of the
NAPI polling cycle.
Patch 2 introduces these changes.
4. Rx URB completion
A new URB is no longer submitted as part of the URB completion
callback.
New URBs are submitted during the NAPI polling cycle.
Patch 3 introduces these changes.
5. Rx URB processing
Completed URBs are put on to queue for processing (as is done in the
current driver). Network packets in completed URBs are copied from
the URB buffer in to dynamically allocated SKBs and passed to
the network stack.
The emptied URBs are resubmitted to the USB host controller.
Patch 3 introduces this change. Patch 6 updates the change to use
NAPI SKBs.
Each packet passed to the network stack is a single NAPI work item.
If the NAPI work budget is exhausted the remaining packets in the
URB are put onto an overflow queue that is processed at the start
of the next NAPI cycle.
Patch 6 introduces this change.
6. Driver-specific hard_header_len
The driver-specific hard_header_len adjustment was removed as it
broke generic receive offload (GRO) processing. Moreover, it was no
longer required due the change in Tx pending data management (see
point 3. above).
Patch 5 introduces this change.
The modification has been tested on four different target machines:
Target | CPU | ARCH | cores | kernel | RAM |

Dell T3620 | Core i3 | x86_64 | 2+2 | 64-bit | 16 GB |
The targets, apart from the Compaq, each have an on-chip USB3 host
controller. A PCIe-based USB3 host controller card was added to the
Compaq to provide the necessary USB3 host interface.
The network throughput was measured using iperf3. The peer device was
a second Dell T3620 fitted with an Intel i210 network interface. The
target machine and the peer device were connected via a Netgear GS105
gigabit switch.
The CPU load was measured using mpstat running on the target machine.
The tables below summarise the throughput and CPU load improvements
achieved by the updated driver.
The bandwidth is the average bandwidth reported by iperf3 at the end
of a 60-second test.
The percentage idle figure is the average idle reported across all
CPU cores on the target machine for the duration of the test.

A pool of Rx URBs is created during driver instantiation. All the

The chosen sizes provide good USB utilisation with little impact on

Completed URBs are processed in the driver bottom half. The URB
buffer contents are copied to a dynamically allocated SKB, which is

the USB host controller.
NOTE: the call to skb_copy() in rx_process() that copies the URB
contents to a new SKB is a temporary change to make this patch work
in its own right. This call will be removed when the NAPI processing
is introduced by patch 6 in this patch set.

10GbE Intel Wired LAN Driver Updates 2021-11-17
Radoslaw Tyl says:
The change is a consequence of errors reported by the ixgbevf driver
while starting several virtual guests at the same time on ESX host.
During this, VF was not able to communicate correctly with the PF,
as a result reported "PF still in reset state. Is the PF interface up?"
and then goes to locked state. The only thing left was to reload
the VF driver on the guest OS.
The background of the problem is that the current PFU and VFU
semaphore locking mechanism between sender and receiver may cause
overriding Mailbox memory (VFMBMEM), in such scenario receiver of
the original message will read the invalid, corrupted or one (or more)
message may be lost.
This change is actually as a support for communication with PF ESX
driver and does not contains changes and support for ixgbe driver.
For maintain backward compatibility, previous communication method
has been preserved in the form of LEGACY functions.

Add support to inet v4 raw sockets for binding to nonlocal addresses
through the IP_FREEBIND and IP_TRANSPARENT socket options, as well as
the ipv4.ip_nonlocal_bind kernel parameter.
Add helper function to inet_sock.h to check for bind address validity on
the base of the address type and whether nonlocal address are enabled
for the socket via any of the sockopts/sysctl, deduplicating checks in
ipv4/ping.c, ipv4/af_inet.c, ipv6/af_inet6.c (for mapped v4->v6
addresses), and ipv4/raw.c.
Add test cases with IP[V6]_FREEBIND verifying that both v4 and v6 raw
sockets support binding to nonlocal addresses after the change. Add
necessary support for the test cases to nettest.

L1.2 is enabled. I have a test system with RTL8168h that gives a
number of rx_missed errors when running iperf and L1.2 is enabled.
With L1.2 disabled (and L1 + L1.1 active) everything is fine.
See also [0]. Can't test this, but L1 + L1.1 being active should be
sufficient to reach higher package power saving states.

Bluetooth: Ignore HCI_ERROR_CANCELLED_BY_HOST on adv set terminated event
This event is received when the controller stops advertising,
specifically for these three reasons:
(a) Connection is successfully created (success).
(b) Timeout is reached (error).
(c) Number of advertising events is reached (error).
(*) This event is NOT generated when the host stops the advertisement.
Refer to the BT spec ver 5.3 vol 4 part E sec 7.7.65.18. Note that the
section was revised from BT spec ver 5.0 vol 2 part E sec 7.7.65.18
which was ambiguous about (*).
Some chips (e.g. RTL8822CE) send this event when the host stops the
advertisement with status = HCI_ERROR_CANCELLED_BY_HOST (due to (*)
above). This is treated as an error and the advertisement will be
removed and userspace will be informed via MGMT event.
On suspend, we are supposed to temporarily disable advertisements,
and continue advertising on resume. However, due to the behavior
above, the advertisements are removed instead.
This patch returns early if HCI_ERROR_CANCELLED_BY_HOST is received.
