Subject: htb offload support in i40e (intel nic)
Date: Wed, 29 Dec 2021 20:50:44 +0100 [thread overview]
Message-ID: <1429844592.20211229205044@nowatel.com> (raw)
Hi,
I saw that the htb offload needs additional changes in the mlx5 driver to support it.
I couldn't find any info regarding the htb offload support on any other drivers/vendors like intel
nic (i40e) We use multiple XL710 that seems to support hardware tc queues:
qdisc noqueue 0: dev lo root refcnt 2

Is this enough to support the htb offload or we must wait for the driver update to support it?
Greetings,
