We're seeing problems where 7.2-PL and 6.3-PL were not affected on the same hardware. The problem is that forcing the duplex 100/full on both=20 sides no longer functions. Configuration: =20 - A variety of Cisco L2/L3 switches over the last decade: -- 2848G-L3 -- 2950 -- 2960s -- 3550-12Ts -- 3550XLs -- Duplex forced 100/full on Cisco side - FreeBSD/amd64 RELENG_8 or 9-CURRENT with duplex forced '100baseTX mediaopt full-duplex', - This configuration has worked since FreeBSD 5.4 =20 When connected to PowerEdge 1850r1/r2, with the onboard Intel=20 82541EI, the parenthesis show an actual media speed/duplex of: media: Ethernet 100baseTX (100baseTX ) The same configuration using a Dell-sold Intel dual port 82546EB, in the same system, on the same switch, works fine. ----------------- ifconfig(8): ----------------- em3: flags=3D8843 metric 0 mtu 1500 options=3D9b ether 00:13:72:4f:70:81 inet 192.168.97.20 netmask 0xffffff80 broadcast 192.168.97.127 media: Ethernet 100baseTX (100baseTX ) status: active ----------------- em0: flags=3D8843 metric 0 mtu 1500> options=3D9b ether 00:04:23:c8:fe:ac media: Ethernet 100baseTX status: active ----------------- ----------------- pciconf(8): ----------------- em3@pci0:7:8:0: class=3D0x020000 card=3D0x016d1028 chip=3D0x10768086=20 rev=3D0x05 hdr=3D0x00 vendor =3D 'Intel Corporation' device =3D 'Gigabit Ethernet Controller (82541EI)' class =3D network subclass =3D ethernet em0@pci0:3:11:0: class=3D0x020000 card=3D0x10128086 chip=3D0x10108086 rev= =3D0x01 hdr=3D0x00 vendor =3D 'Intel Corporation' device =3D 'Dual Port Gigabit Ethernet Controller (Copper) (82546EB)' class =3D network subclass =3D ethernet ----------------- rc.conf(5) for shits & giggles: ifconfig_em0=3D"inet X netmask Y media 100baseTX mediaopt full-duplex" ifconfig_em3=3D"inet Z netmask F media 100baseTX mediaopt full-duplex" -------- Example IOS switch config: interface FastEthernet0/39 description I hate Dell switchport access vlan 100 switchport mode access speed 100 duplex full spanning-tree portfast end -------- I've been clearing interface counters on the switch side, but I'll send 'netstat -i', 'show interface counters', and 'sudo sysctl -w dev.em.3.stats=3D1' ASAP to illustrate connectivity errors soon. Are we being punished for patronizing Dell? Is it possible that ifconfig(8) output has simply changed? Are the values in the parenthesis on the right the Ethernet auto-sense desired values where as outside the parenthesis the current active values? In 6.3/7.2, once you forced a speed/duplex, the values in parenthesis went away entirely.=20 The only way I've been able to make that happen is to #define in src/sys/dev/e1000/if_em.h: #define DO_AUTO_NEG 0 /* * This parameter control whether or not the driver will wait for * autonegotiation to complete. * 1 - Wait for autonegotiation to complete * 0 - Don't wait for autonegotiation to complete */ Also seems odd that some ICs are affected but not others. Its also possible that my problems are pf(4) + setfib(8) related and I that this is a separate issue. Two new notes since the original post: - I have confirmed this problem on two revisions of the Dell 8th gen hardware in two different datacenters - The problem persists on -CURRENT from 05/2010 - RELENG_7 does not seem to be impacted - More stats below.
