vmxnet3 version 6 supports some new features, including but
not limited to:
- Increased max MTU up to 9190
- Increased max number of queues, both for RX and TX
- Removes power-of-two limitations
- Extended interrupt structures, required implementation for
additional number of queues
Tested, using testpmd, for different hardware version on
ESXi 7.0 Update 2.

To: jbehrens, yongwang; +Cc: dev, pagupta
Currently the driver assumes that the size of the reta table is
four times the number of rx queues at multiple places. However,
it sets it to four times the maximum number of queues (4 * 32 = 128)
when it first initializes the device. Change the other uses to use
the stored value, not the assumed default.

Please, fix prefix for all patches. It should be "net/vmxnet3: ".
Summary after prefix should start from small letter and be in

In general, addition order does not matter and it is
recommended to follow order in eth_dev_ops here (and
where functions are declared, and where functions are
defined).

Correct. E.g. our appliance uses it in the production data plane, not just for debugging. We only need the function to return an approximate number, though.

I'm wondering if is really IPv4/IPv6 fragmented packets or just
scattered on Rx across many Rx buffers.
I'm asking since fragmented sounds weird with TCP, since TCP

Is it a bug fix? If so, it requires corresponding "Fixes:" tag and Cc to

Hi Andrew,
Changes done in this patch was accidentally removed in commit 046f1161956777e3afb13504acbe8df2ec3a383c.
This was noticed later and we are trying to address this here.

Hi Andrew,
Packet type was not set for fragmented packets so we are trying to set it in all possible scenarios.
I believe TCP packets can be fragmented.

User RETA instead of reta in commit message
Fix the issue thrown by checkpatches.sh in file drivers/net/vmxnet3/vmxnet3_ethdev.c

"Fixes: 046f11619567 ("net/vmxnet3: support MSI-X interrupt")"
v3:
adding Reviewed-by info in all the patches
v2:
address review comments from Andrew Rybchenko andrew.rybchenko@oktetlabs.ru

Driver callbacks initialization should follow callbacks order in the
structure definition.
Do not reorder callbacks implementation to avoid extra noise in
the code.

VMXNET3 version 6 supports some new features, including but not limited to:
- Increased max MTU up to 9190
- Increased max number of queues, both for Rx and Tx
- Removes power-of-two limitations
- Extended interrupt structures, required implementation for
additional number of queues
Tested, using testpmd, for different hardware versions on ESXi 7.0
Update 2.

Currently the driver assumes that the size of the RETA table is
four times the number of Rx queues at multiple places. However,
it sets it to four times the maximum number of queues (4 * 32 = 128)
when it first initializes the device. Change the other uses to use
the stored value, not the assumed default.
Tested, using testpmd, for different hardware versions on ESXi 7.0
Update 2.

Hi Pankaj,
I did final cleanup before applying the patch series, but
realized that release notes update is missing.
Please, pick up my changes and amend patches which support
new features with release notes update in the documentation.
Everything else LGTM now.

Hi Andrew,
New features were introduced in following two patches so I will update release_22_07.rst for these two patches.
[PATCH v6 1/9] net/vmxnet3: add version 5 support
[PATCH v6 6/9] net/vmxnet3: add version 6 support
Let me know if I am missing anything.
Thanks,
Pankaj

Hi Pankai,
I'd consider a patch which adds RETA controls as well. IMHO it
is a major feature which could be interesting to end users.

Andrew.
