No, I tried combinations of repluging UTP cable and repluging the device itself, but the resuts are always the same. It receives packets from the wire, but it cannot send one. But I noticed one thing now. I also have em0/em1 interfaces, and I am switching with ue0 when I test AXE. It turned out that although I 'ifconfig em0 inet delete down' those unused interfaces, the arp table entries remain. 'arp -nda' shows 'delete: cannot locate 192.168.1.1' and the like for every entry in the table, and they are infact not deleted. Deletion fails both when em0 is up and down. Then again, this time I booted with a configuration such that em0/em1 are not touched at all, and axe device plugged with UTP cable from the very start (before powering on), and the symptom is the same (recive OK, send NG), and this time the arp table has the single line which corresponds to self address of ue0/AXE. I am rebuilding my userland world now, just to make sure (it used to be Dec. 2008 snapshot), but are there anything that may be out of sync in the December-Feburary time slot? Anyway, this should take some good while. After that, I will try a kernel without USB1 nor USB2 configured, and will load the modules manually as you have done, with your attached patches. > > > Does netstat indicate any receive errors on the AXE interface? > > > > > > netstat -i > > > > Nope. > > > > Name Mtu Network Address Ipkts Ierrs Opkts Oerrs Coll > > ... > > ue0 1500 <Link#4> 00:90:cc:f7:bc:2e 52 0 12 0 0 > > ue0 1500 192.168.1.0 192.168.1.3 0 - 4 - - > > > > The latter line is the result of statically asigning an address, > > and then 'ping -n 192.168.1.1'ing for four seconds. > > > > > Maybe "Pyun YongHyeon" should have a look at this. > > > > > > And you are running the latest current? > > > > I updated to -current as of about an hour or two ago. > > > > PS.
