My machine has the following em(4) device and it has a autoneg problem. When I was using 8-stable kernel at 2010/11/01, it has no problem. But I update to 8-stable at 2010/12/01, the kernel is only linked up as 10M. e...@pci0:0:25:0:class=0x02 card=0x13d510cf chip=0x104a8086 rev=0x02 hdr=0x00 vendor = 'Intel Corporation' device = '82566DM Gigabit Network Connection' class = network subclass = ethernet --- TAKAHASHI Yoshihiro ___ freebsd-net@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-net To unsubscribe, send any mail to "freebsd-net-unsubscr...@freebsd.org"

Supermicro Bladeserver
I am trying to track down a problem being experienced at icir.org using SuperMicro bladeservers, the SERDES 82575 interfaces are having connectivity or perhaps autoneg problems, resulting in link transitions and watchdog resets. The closest hardware my org at Intel has is a Fujitsu server who's blades also have this device, but testing on that has failed to repro the problem. I was wondering if anyone else out there has this hardware, if so could you let me know your experience, have you had problems or not, etc etc? Thanks much for any information!

It's likely that the mbuf handling problem (in em_refresh_mbufs()) is triggered by the processing you're doing with ipfw (or elsewhere for that matter), so, yes, I think it's a bug fixed in the revision discussed.

net80211 11n fixes: Begin handling 11n channel status flags
Hi all, Here's the first 11n related patch to push into -HEAD. This adds handling 11na/11ng HT/20 channel flags when scanning for access points. Without this patch, 11na/11ng APs aren't considered for association. I'd like to push this into -HEAD and a modified version of it into -8. With this, my modified ath+hal driver can be built as a module and installed for testing without any further kernel changes. http://people.freebsd.org/~adrian/ath/net80211_11n_fixes_1.diff I'll look at getting HT/40 modes working at a later date.
