Serious bandwidth regression in if_axe (uether)

Wed Mar 2 13:24:16 UTC 2011

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?

Thanks in advance,

  Marcus
