Just for reference, booting 3 distinct bectl environments that are on the same media: # uname -apKU FreeBSD CA72_4c8G_ZFS 14.0-CURRENT FreeBSD 14.0-CURRENT #4 main-n247017-e5f5b6a75c0a-dirty: Sat May 29 01:08:39 PDT 2021 root@CA72_16Gp_ZFS:/usr/obj/BUILDs/main-CA72-nodbg-clang/usr/main-src/arm64.aarch64/sys/GENERIC-NODBG-CA72 arm64 aarch64 1400017 1400017 # sysctl net.inet.tcp.lro net.inet.tcp.lro.without_m_ackcmp: 0 net.inet.tcp.lro.with_m_ackcmp: 0 net.inet.tcp.lro.would_have_but: 0 net.inet.tcp.lro.extra_mbuf: 0 net.inet.tcp.lro.lockcnt: 0 net.inet.tcp.lro.compressed: 0 net.inet.tcp.lro.wokeup: 0 net.inet.tcp.lro.fullqueue: 0 net.inet.tcp.lro.entries: 8 # uname -apKU FreeBSD CA72_4c8G_ZFS 13.0-RELEASE-p1 FreeBSD 13.0-RELEASE-p1 #1 releng/13.0-n244744-8023e729a521-dirty: Wed May 26 15:20:08 PDT 2021 root@CA72_4c8G_ZFS:/usr/obj/BUILDs/13_0R-CA72-nodbg-clang/usr/13_0R-src/arm64.aarch64/sys/GENERIC-NODBG-CA72 arm64 aarch64 1300139 1300139 # sysctl net.inet.tcp.lro net.inet.tcp.lro.sackwakeups: 0 net.inet.tcp.lro.lockcnt: 0 net.inet.tcp.lro.single: 0 net.inet.tcp.lro.compressed: 0 net.inet.tcp.lro.wokeup: 0 net.inet.tcp.lro.fullqueue: 0 net.inet.tcp.lro.entries: 8 net.inet.tcp.lro.hold_lock: 0 # uname -apKU FreeBSD CA72_4c8G_ZFS 13.0-STABLE FreeBSD 13.0-STABLE #2 stable/13-n245765-bec0d2c9c841-dirty: Thu May 27 14:16:42 PDT 2021 root@CA72_4c8G_ZFS:/usr/obj/BUILDs/13S-CA72-nodbg-clang/usr/13S-src/arm64.aarch64/sys/GENERIC-NODBG-CA72 arm64 aarch64 1300505 1300505 # sysctl net.inet.tcp.lro net.inet.tcp.lro.sackwakeups: 0 net.inet.tcp.lro.lockcnt: 0 net.inet.tcp.lro.single: 0 net.inet.tcp.lro.compressed: 0 net.inet.tcp.lro.wokeup: 0 net.inet.tcp.lro.fullqueue: 0 net.inet.tcp.lro.entries: 8 net.inet.tcp.lro.hold_lock: 0 So the releng/13.0 and stable/13 have net.inet.tcp.lro.sackwakeups and the like but main does not. Note: I do use a USB3 EtherNet dongle instead of genet0, in case that matters. === Mark Millard marklmi at yahoo.com ( dsl-only.net went away in early 2018-Mar)home | help
