Hi,

David and I have committed some fixes to 7-STABLE tree, and I think all
important bce(4) fixes has been merged now.  If you have bce(4)
interfaces PLEASE help us to test them, the simplest way of doing this
is to sync your code with RELENG_7 and rebuild kernel. [1]

For those who can't test this under 7-STABLE environment, I have
extracted corresponding files here:

	http://people.freebsd.org/~delphij/misc/193358.tar.bz2

Once can extract the tarball over /usr/src/ in order to overwrite your
files, this should be applicable for a 7.2-RELEASE system.

Known issues that this should have resolved:

 - "PHY write timeout!" when you can find "ukphy" in your dmesg output,
some blade servers [Dell T610?] may have this, in particular;
 - incorrect input traffic accounting. (netstat 1 would show larger
input traffic);
 - under heavy load there might be some data corruption;

Please let us know if these changes would bring any regressions, thanks
a lot!

[1] Please note that, because bce(4) is part of GENERIC kernel so you
may need to do a full "make kernel" instead of just
rebuilding/installing corresponding kernel module.

Cheers,
