It is not implemented yet. > >Another missing feature from both drivers is the support for RSS larger >than 16: > > >https://github.com/fastly/linux/commit/76b88a7d4f176966cad52087c7750ab5af1771e4 > >The same question: is there a reason why it's not supported by drivers? This is due to HW limitation - the indirection table for RSS is configured via the RETA register which has 4 bits for each entry hence the 16 queue limit for RSS. The comment in the above patch is incorrect - the README mentions the total number of queues (64) not RSS.
