This causes extremely erratic but consistent slow connections. Took me ages to troubleshoot. Had the same behavior under openindiana. Using the flags from above I would get consistent linespeed. igb0@pci0:0:20:0: class=3D0x020000 rev=3D0x03 hdr=3D0x00 vendor=3D0x8= 086 device=3D0x1f41 subvendor=3D0x15d9 subdevice=3D0x1f41 vendor =3D 'Intel Corporation' device =3D 'Ethernet Connection I354' class =3D network subclass =3D ethernet --=20 You are receiving this mail because: You are the assignee for the bug.=
