I was surprised to see that it is not included in any KERNCONF, or even in = NOTES so it is part of LINT. Is there a particular reason why it's not = at least in NOTES?

But as I investigated further, step by step, I realized that hardly anyone is actually using it. The code still exists here and there, but it’s rarely built. People seem either cautious or unconvinced about any real advantages of these code samples hidden under #ifdefs. At times, RSS feels like a kind of "snake oil" among kernel options. That said, the code is still buildable. One genuinely beneficial feature for me is the change in ECMP routing - the way hashing, tuples, etc, are calculated differs depending on whether "options RSS" is enabled. When RSS is used, the paths are just more predictable for UDP. I have not really read or studied the code, but rather looked how packets are forwarded. ECMP routing with FreeBSD is quite a new feature, introduced by melifaro@ with netlink(4). People rarely use FreeBSD as a router nowadays, so the feedback is limited and very narrow. Another, perhaps more subjective, observation is that when a BGP session is established and the router is pulling the full-view routing table - or when it’s stressed by a high packet-per-second load in a congested network - performance seems better with both "options RSS" and net.isr.dispatch="deferred" enabled. In these cases, routing feels faster, packet latency is lower, and the improvement is noticeable, for example, in the audio quality of VoIP calls, I had not taken any measures though. Good luck with adding "options RSS" to one of the standard kernel configs! Cheers!

This is very appreciated. Please note that upload and download bandwidth can be different, I would not assume that this is due to the interface. What I conclude from your measurements is that I do not see any indications anymore for checksum errors. I am not saying that the vtnet driver is perfe= ct, just that I have no indication that the problem originally reported still persists. So I would be inclined to close this bug. What do you think? I you still have an issue needing to be investigated, I would suggest to op= en a new bug report and track it there. But the checksum issue seems to be resol= ved. --=20 You are receiving this mail because: You are on the CC list for the bug.= From nobody Tue Oct 21 21:05:31 2025 X-Original-To: net@mlmmj.nyi.freebsd.org Received: from mx1.freebsd.org (mx1.freebsd.org [IPv6:2610:1c1:1:606c::19:1]) by mlmmj.nyi.freebsd.org (Postfix) with ESMTP id 4crlF71w7Sz6D0mc for ; Tue, 21 Oct 2025 21:05:31 +0000 (UTC) (envelope-from bugzilla-noreply@freebsd.org) Received: from mxrelay.nyi.freebsd.org (mxrelay.nyi.freebsd.org [IPv6:2610:1c1:1:606c::19:3]) (using TLSv1.3 with cipher TLS_AES_256_GCM_SHA384 (256/256 bits) key-exchange X25519 server-signature RSA-PSS (4096 bits) server-digest SHA256 client-signature RSA-PSS (4096 bits) client-digest SHA256) (Client CN "mxrelay.nyi.freebsd.org", Issuer "R12" (verified OK)) by mx1.freebsd.org (Postfix) with ESMTPS id 4crlF718qQz431l for ; Tue, 21 Oct 2025 21:05:31 +0000 (UTC) (envelope-from bugzilla-noreply@freebsd.org) DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/relaxed; d=freebsd.org; s=dkim; t=1761080731; h=from:from:reply-to:subject:subject:date:date:message-id:message-id: to:to:cc:mime-version:mime-version:content-type:content-type: content-transfer-encoding:content-transfer-encoding: in-reply-to:in-reply-to:references:references; bh=iQudviqHCSzsacUu63rLKztqklD314DM3lLBjoufXm4=; b=vbwaNI3YbIXLMTZbb4//ehhIfjHXayPWEac6IJ+IEcRi/MHv4+jcjdMq10QAfJLGV1idv2 Ho24Nv/mTZKPBpCbg0GD+FYfvEG+lq6iHZPikiMAK0jlCcB2F6/g/V95qITFcjAPOFyQ9m O901kCgO18HKtekPt56rPdz0y94v2Nd012ujoVLzNpFoxmbsEZRk0P/xHGyP4fv9/S1/ZV 4rbNGzH8XqK+BoN56CL7Lk0Rd1YUBXXh4pwTTLkdYHTne+21WmHQByB01j9CCeL0YtTUrS G2HoxRpPah8SeduER6wQ+ZuDSNRod7URLcmrIvPEkentkL04KVUM49s1KPB2pg== ARC-Message-Signature: i=1; a=rsa-sha256; c=relaxed/relaxed; d=freebsd.org; s=dkim; t=1761080731; h=from:from:reply-to:subject:subject:date:date:message-id:message-id: to:to:cc:mime-version:mime-version:content-type:content-type: content-transfer-encoding:content-transfer-encoding: in-reply-to:in-reply-to:references:references; bh=iQudviqHCSzsacUu63rLKztqklD314DM3lLBjoufXm4=; b=aSS1vsJ4qNcenSeMS43jcipvqQnaWffkN7BmGBJYAhLQVhuNY4FtMRDPKt3HxEAd/aR4j6 2qq29o9QDnZ7jRyx0Ujh2oj6/KCwnxM3Q3riDlOCSel4QybSYTfg5rgoyuNb1y2N7ocvUb kWudkgf37aPnojg1ScLde68U9gvL47Ct3FY+F7gUetlsgmSUQWcRjLr9vW7nCBT3zI2wQO S4iM46+miHhPa5hDkz/oNsIuYw529n8zkXeQlupCv4EfLNIN0oZ1Y2ulaepRUFZYEpv4mz zDezh1hm2gJqQdDjifKhTg3dGAy/Cn5REPF4YtYYZhQc+PU48J+OmiRx0h335A== ARC-Seal: i=1; s=dkim; d=freebsd.org; t=1761080731; a=rsa-sha256; cv=none; b=R87BbLGiPkO7CRKEOvFTMam5H3e/ukLVg0WBagiEbxuIlIBPa4YaGmjHFyTETYYD5IgR/8 BM92lmaslPsC2jMP41vTXRs50v9LYeftL/ctkCMVn61n7bhXYij/G6U7CCLSOly6mp2Z8H eYezIP5FJ0ZP/wNJD2v8Vga2nseo+vG57V9KAi3Rj132/sNmHWUYmh/7i8MQPOkbH7h3+R g81LGRn/EWiWd6nG4sk4YfYcgi3pYZXhLaIyzRv2pO71BvZZYFjZMSdew89WC8i9EV3cKu kapu+F6u1tIAv7XWvIHO7B/uWbwrb86dTkqYake46MHW3zwXN42HxSwGL2ZOig== ARC-Authentication-Results: i=1; mx1.freebsd.org; none Received: from kenobi.freebsd.org (kenobi.freebsd.org [IPv6:2610:1c1:1:606c::50:1d]) (using TLSv1.3 with cipher TLS_AES_256_GCM_SHA384 (256/256 bits) key-exchange X25519 server-signature RSA-PSS (4096 bits) server-digest SHA256) (Client did not present a certificate) by mxrelay.nyi.freebsd.org (Postfix) with ESMTPS id 4crlF70gVKz1F2N for ; Tue, 21 Oct 2025 21:05:31 +0000 (UTC) (envelope-from bugzilla-noreply@freebsd.org) Received: from kenobi.freebsd.org ([127.0.1.5]) by kenobi.freebsd.org (8.15.2/8.15.2) with ESMTP id 59LL5UP4011053 for ; Tue, 21 Oct 2025 21:05:30 GMT (envelope-from bugzilla-noreply@freebsd.org) Received: (from www@localhost) by kenobi.freebsd.org (8.15.2/8.15.2/Submit) id 59LL5UiK011051 for net@FreeBSD.org; Tue, 21 Oct 2025 21:05:30 GMT (envelope-from bugzilla-noreply@freebsd.org) X-Authentication-Warning: kenobi.freebsd.org: www set sender to bugzilla-noreply@freebsd.org using -f From: bugzilla-noreply@freebsd.org To: net@FreeBSD.org Subject: [Bug 276760] vtnet driver incorrectly calculates checksums Date: Tue, 21 Oct 2025 21:05:31 +0000 X-Bugzilla-Reason: CC X-Bugzilla-Type: changed X-Bugzilla-Watch-Reason: None X-Bugzilla-Product: Base System X-Bugzilla-Component: kern X-Bugzilla-Version: 13.2-STABLE X-Bugzilla-Keywords: X-Bugzilla-Severity: Affects Some People X-Bugzilla-Who: vova@fbsd.ru X-Bugzilla-Status: In Progress X-Bugzilla-Resolution: X-Bugzilla-Priority: --- X-Bugzilla-Assigned-To: tuexen@freebsd.org X-Bugzilla-Flags: X-Bugzilla-Changed-Fields: Message-ID: In-Reply-To: References: Content-Transfer-Encoding: quoted-printable Content-Type: text/plain; charset="UTF-8" X-Bugzilla-URL: https://bugs.freebsd.org/bugzilla/ Auto-Submitted: auto-generated List-Id: Networking and TCP/IP with FreeBSD List-Archive: https://lists.freebsd.org/archives/freebsd-net List-Help: List-Post: List-Subscribe: List-Unsubscribe: Sender: owner-freebsd-net@FreeBSD.org MIME-Version: 1.0 https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D276760 --- Comment #38 from vova@fbsd.ru --- (In reply to Michael Tuexen from comment #37) No objections to close the bug from my side.
