Hi, Following http://article.gmane.org/gmane.os.openbsd.tech/47475, I have a similar problem with svlan(4) and em(4) (Intel 80003ES2). The main difference with bge(4) is that ping works with em(4) but not tcp/udp. (obviously my bge(4) supports IFCAP_CSUM_IPv4 and not my em(4)). Everything works fine with IPv6 as the TCO capabilities are not supported by these chips. Also everything is fine if I don't use svlan(4).
With TCO : ---------------------------- # ssh root@185.22.128.253 ssh: connect to host 185.22.128.253 port 22: Operation timed out ---------------------------- Comment lines 1851-1854 of if_em.c to disable TCO, make && make install and reboot. (network/system/pf config are the same) Without TCO : ---------------------------- # ssh root@185.22.128.253 The authenticity of host '185.22.128.253 (185.22.128.253)' can't be established. ECDSA key fingerprint is SHA256:Mm4f4qaEuFBUZRoNTOccKdVLPdkISXU2f8v6oz9itec. Are you sure you want to continue connecting (yes/no)? ---------------------------- dmesg : ---------------------------- OpenBSD 5.9-beta (GENERIC) #0: Sun Jan 10 14:41:37 CET 2016 r...@test3.lab.ledeuns.net:/usr/src/sys/arch/amd64/compile/GENERIC RTC BIOS diagnostic error 3 real mem = 8566259712 (8169MB) avail mem = 8302551040 (7917MB) mpath0 at root scsibus0 at mpath0: 256 targets mainbus0 at root bios0 at mainbus0: SMBIOS rev. 2.5 @ 0x9fa32000 (69 entries) bios0: vendor Intel Corporation version "S5000.86B.10.00.0094.101320081858" date 10/13/2008 bios0: Rackable Systems Inc.
