When net.link.ether.bridge=1 is first set, the bridge appears to pass ALL traffic normally for a period of time less than 1 second. After that, it appears as if about 98% of traffic is lost. I cannot determine if the kernel has a preference for forwarding some packets and not others. On a server with 2 NICs that will be doing nothing but bridging from one interface to another: Name Mtu Network Address Ipkts Ierrs Opkts Oerrs Coll xl0 1500 <Link#1> 00:50:04:68:61:12 221887 0 1 0 0 xl1 1500 <Link#2> 00:50:04:9d:67:c6 0 0 8533 0 0 No messages are logged indicating what is happening to those 200,000+ packets that should have been bridged. >How-To-Repeat: Problem is always repeatable across differing hardware, across 4.6.2, 4.6.1, 4.4 (have not tried other version), & with PicoBSD. Problem is repeatable both with GENERIC kernel and my own custom kernel. Occurs with both xl and fxp NICs (have not tried others). Have tried on intel and asus/via mobos. >Fix: unknown >Release-Note: >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
