ISTR that wm(4) has one or more bugs concerning flow control. It's possible that when flow control is negotiated, the MAC is not set up to respect flow control signals, so it keeps sends frames to the peer after it is asked to pause. With all buffers full, the peer drops the frames on the floor. This would be an important bug to fix. Does your switch tell how many frames are dropped?The switch doesn't tell anything! :) It's a real el-cheapo - US$15, purchased locally here in the Philppines. (And I've seen adverts for even less, US$12!)FWIW, this is a D-Link DEC-1008A 8-port 10/100 with auto-MDI/MDIX.
