Description Stefan Richter 2008-12-13 05:15:30 UTC

When I looked at it in March, the AR handler did not handle large packets entirely correctly.  I didn't verify again right now but the problem is presumably still there.

Comment 2 Stefan Richter 2010-10-31 12:39:15 UTC

The patches from comment 1 work for me.

Comment 3 Stefan Richter 2010-11-06 08:31:08 UTC

Fixes merged into mainline, to appear in 2.6.37-rc2, also submitted for inclusion into currently active stable series.

Comment 4 Stefan Richter 2010-11-08 14:43:57 UTC

Wait, what was I thinking?  While there were corrections regarding reassembly of packets that cross page boundaries, 4kB sized packets are still not handled.
