Subject: [dpdk-dev] Symmetric hashing not working in ESXI version 7.0.0
Date: Mon, 27 Sep 2021 01:03:19 +0530	[thread overview]
Message-ID: <CALYHa1ttQ8N_C4sNnWQ1X-gWMcGyBLj1uTW4FsLP0jvB0ausxg@mail.gmail.com> (raw)

Hi Everyone,



                We are facing an issue with symmetric hashing. Below is the
definition of symmetric hashing.



The traffic from server A to server B and server B to server A should fall
under the same flow. This is what we call symmetricity.



I have configured the customized keys for symmetric hashing as suggested in
the DPDK forum. After changing the key to the below symmetric hashing
started working.



*static uint8_t hash_key[RSS_HASH_KEY_LENGTH] = {*

*        0x6D, 0x5A, 0x6D, 0x5A, 0x6D, 0x5A, 0x6D, 0x5A,*

*        0x6D, 0x5A, 0x6D, 0x5A, 0x6D, 0x5A, 0x6D, 0x5A,*

*        0x6D, 0x5A, 0x6D, 0x5A, 0x6D, 0x5A, 0x6D, 0x5A,*

*        0x6D, 0x5A, 0x6D, 0x5A, 0x6D, 0x5A, 0x6D, 0x5A,*

*        0x6D, 0x5A, 0x6D, 0x5A, 0x6D, 0x5A, 0x6D, 0x5A,*

*};*



*But it is working in ESXI server version 6.7.0, but does not work in ESXi
server version 7.0.0.*



Anyone aware of this issue. *We are using the vmxnet3 driver and DPDK
version 19.11.*



Regards,

Ramkumar N.
