Just to add that the current workaround (except staying with the pre-5.8 kernel of course) is to install the kmod-tg3-rhel5u7 from the CentOS updates repository.
Even if it's marked as 5u7, it will work on 5.8 and fixes the 802.1q issue introduced in the tg3 module from the 5.8 kernel

According to bleve, the bug will be fixed in the upstream kernel. The patch comes from:

linus tree commit 5c1e688388f629e8d8e88183b5ebc21e209252aa

I have uploaded the centos patch to be included in the next release of centosplus kernel.

Does anyone know if this issue has been addressed upstream?

The RH Bugzilla link gives me "You are not authorized to access bug #798939.".

Upstream BZ 798939 was marked as a duplicate of BZ 797011 which is also inaccessible.

kernel-2.6.18-308.4.1.el5 was released upstream today. The patch noted in 14693 was not there. The centosplus kernel is being built with the patch.

kernel-2.6.18-308.4.1.el5.centos.plus fixed this issue for me, although I still see tg3 dump in dmesg

Anyone wishing to try tg3 version 3.122 (latest from Broadcom) can do so by installing kmod-tg3 from ELRepo:
