For more info: https://lwn.net/Articles/845120/ https://lwn.net/Articles/845207/ * selftests: test multiple parallel streams * qemu: bump default kernel version Usual test harness improvements. * peer: put frequently used members above cache lines * device: do not generate ICMP for non-IP packets * queueing: get rid of per-peer ring buffers Most notable here is the queueing commit. Having two ring buffers per-peer means that every peer resulted in two massive ring allocations. On an 8-core x86_64 machine, this commit reduces the per-peer allocation from 18,688 bytes to 1,856 bytes, which is an 90% reduction. With some single-machine deployments approaching 500,000 peers, we're talking about a reduction from 7 gigs of memory down to 700 megs of memory. This release contains commits from: Jason A. Donenfeld and Thadeu Lima de Souza Cascardo.
