i40e MAC filter hash state failed

SantoshSingh — Tue, 08 Aug 2023 20:38:38 GMT

Hi,

I am seeing an issue where the VLAN tagged packets are being dropped by the NIC.

Using "ethtool -S" I can see that the "port.rx_unicast " counters are incrementing but its not being forwarded to the right interface.

I posted this question under "Ethernet Products" support category and was asked to post it in this category, below is the detail.

https://community.intel.com/t5/Ethernet-Products/i40e-MAC-filter-hash-state-failed/m-p/1508175/emcs_t/S2h8ZW1haWx8dG9waWNfc3Vic2NyaXB0aW9ufExLSVFBWUlFNk5WTlZDfDE1MDgxNzV8U1VCU0NSSVBUSU9OU3xoSw#M33955

I am seeing a bunch of following error message from driver -

It appears that there is no more space in the MAC Filter HT.

Can someone please confirm this?

Also, is there any way to disable this "MAC Filter" in NIC and make it accept ALL the VLAN tagged packets?

Thanks & Regards,

Santosh
