Commit 39f9895a00f4 ("vmxnet3: add support for 32 Tx/Rx queues")

vmxnet3: correctly report encapsulated LRO packet

2022-12-02T10:30:07+00:00

Commit dacce2be3312 ("vmxnet3: add geneve and vxlan tunnel offload
support") added support for encapsulation offload. However, the
pathc did not report correctly the encapsulated packet which is
LRO'ed by the hypervisor.

This patch fixes this issue by using correct callback for the LRO'ed
encapsulated packet.

net: drop the weight argument from netif_napi_add

2022-09-29T01:57:14+00:00

We tell driver developers to always pass NAPI_POLL_WEIGHT
as the weight to netif_napi_add(). This may be confusing
to newcomers, drop the weight argument, those who really
need to tweak the weight can use netif_napi_add_weight().

net: move from strlcpy with unused retval to strscpy

2022-08-31T21:11:07+00:00

Follow the advice of the below link and prefer 'strscpy' in this
subsystem. Conversion is 1:1 because the return value is not used.

vmxnet3: do not reschedule napi for rx processing

2022-07-29T11:11:23+00:00

Commit '2c5a5748105a ("vmxnet3: add support for out of order rx
completion")' added support for out of order rx completion. Within
that patch, an enhancement was done to reschedule napi for processing
rx completions.

However, it can lead to missing an interrupt. So, this patch reverts
that part of the code.

vmxnet3: Record queue number to incoming packets

2022-07-19T03:38:53+00:00

Make generic XDP processing attribute packets to their actual
queues instead of queue #0. This improves AF_XDP performance
considerably since softirq threads no longer fight over single
AF_XDP socket spinlock.

vmxnet3: disable overlay offloads if UPT device does not support

2022-06-20T08:12:46+00:00

'Commit 6f91f4ba046e ("vmxnet3: add support for capability registers")'

to advertize capabilities of the device.

The patch updated the dev_caps to disable outer checksum offload if
PTCR register does not support it. However, it missed to update
other overlay offloads. This patch fixes this issue.

vmxnet3: use ext1 field to indicate encapsulated packet

2022-06-09T10:42:01+00:00

Till vmxnet3 version 6, om field of transmit descriptor was used
to indicate encapsulated offload packet and msscof was used to
indirectly indicate TSO/CSO. From version 7 and later, ext1 field
will be used to indicate whether packet is encapsulated or not and
om fields will continue to indicate if the packet is TSO or CSO.
