Hi, After some time of discussions going forth and back I think there is a very good proposal for implementing support for the SO_MAX_PACING_RATE socket option at: https://reviews.freebsd.org/D3687 Since last time the solution was discussed there has been added RSS awareness to the internal APIs, to better utilize CPU offloading when applying rate limiting. By default, unless options RATELIMIT is defined, there are no functional changes in the current TCP/IP code. I'd like some people from the network group to have a fresh look at the patch and if everything is fine, be able to push something by end of October. At Mellanox we are currently doing final testing of the SO_MAX_PACING_RATE feature. --HPS
