Hi all. I just stumbled across a problem with my network throughput that appears = to be linked to recent changes. In [FreeBSD 8.1-STABLE #10 r214834: Fri = Nov 5 18:20:58 CET 2010] my D-Link DUB-E100 Fast Ethernet USB 2.0 = adapter, configured via if_axe (uether) delivers an expected 20 MBit = throughput (downstream) via my provider (20MBit downstream is the = maximum I get from provider). However starting with [FreeBSD = 8.2-PRERELEASE #11 r217577: Wed Jan 19 16:50:07 CET 2011] the throughput = is down to 5.62 MBit (tested with various reference hosts, 5.62MBit is = the best I got). The latter is also true for 8.2-RELEASE. Is this already a known problem?
