Dear Sascha, the ASIX USB dongle is working on the same hardware running a 4.4 vanilla kernel. The dongle also works on my Linux PC with a 4.13 kernel. I added memory_display(buf, 0, len, 4, 0) to asix_rx_fixup(). Here are the logs: barebox@Atmel at91sam9260-ek:/ usb usb: USB: scanning bus for devices... usb: Bus 001 Device 001: ID 0000:0000 OHCI Root Hub usb: Bus 001 Device 002: ID 0b95:7720 AX88772A mdio_bus: miibus1: probed eth1: got preset MAC address: 8c:ae:4c:eb:1f:83 usb: 2 USB Device(s) found barebox@Atmel at91sam9260-ek:/ eth1.ipaddr=192.168.10.120 barebox@Atmel at91sam9260-ek:/ ethact eth1 barebox@Atmel at91sam9260-ek:/ ping 192.168.10.55 eth1: 100Mbps full duplex link detected 00000000: ffffffc3 ffffffff eaa82a80 06088d6a .........*..j... 00000010: 00080100 01000406 eaa82a80 a8c08d6a .........*..j... 00000020: 0000020a 00000000 6b0aa8c0 00000000 ...........k.... 00000030: 00000000 00000000 00000000 00b90000 ................ 00000040: ffffff46 ffffffff eaa82a80 00088d6a F........*..j... 00000050: ab000045 00400000 986f1140 020aa8c0 E.....@.@.o..... 00000060: ffffffff 1127d7b5 af4b9700 8b000602 ......'...K..... 00000070: 800a0002 6aeaa82a 0aa8c08d 06000102 ....*..j........ 00000080: eaa82a80 000a8d6a c1130004 04000b2a .*..j.......*... 00000090: 544e4255 4203000c 0003325a 2e5a4222 UBNT...BZ2.."BZ. 000000a0: 32377261 762e3034 2e372e33 362e3535 ar7240.v3.7.55.6 000000b0: 2e383033 34303731 312e3331 16363535 308.170413.1556. 000000c0: 2e330b00 35352e37 3033362e 03001538 ..3.7.55.6308... 000000d0: 17325a42 18000100 19000100 1a000100 BZ2............. 000000e0: 13000100 2a800600 8d6aeaa8 00040012 .......*..j..... 000000f0: 1beff801 2e320500 9d342e34 ffc3003c ......2.4.4.<... 00000100: ffffffff 2a80ffff 8d6aeaa8 01000608 .......*..j..... 00000110: 04060008 2a800100 8d6aeaa8 020aa8c0 .......*..j..... 00000120: 00000000 a8c00000 00006b0a 00000000 .........k...... 00000130: 00000000 00000000 00000000 ff4300bc ..............C. 00000140: ffffffff 2a80ffff a88bb2a8 00450008 .......*......E. 00000150: 0000ae00 11400040 a8c0926f ffff050a ....@.@.o....... 00000160: 01adffff 9a001127 0602ccad 00028e00 ....'........... 00000170: a82a800a c0b9bb13 01050aa8 2a800600 ..*............* 00000180: b9bb13a8 0004000a 0b6d6f1a 42550400 .........om...UB 00000190: 000c544e 4c375504 23000354 712e5a42 NT...U7LT..#BZ.q 000001a0: 35396163 762e7836 2e372e33 362e3535 ca956x.v3.7.55.6 000001b0: 2e383033 34303731 312e3331 16303136 308.170413.1610. 000001c0: 2e330b00 35352e37 3033362e 04001538 ..3.7.55.6308... 000001d0: 544c3755 00010017 00010018 00010019 U7LT............ 000001e0: 0001001a 80060013 bb13a82a 040012b9 ........*....... 000001f0: 44a40200 3305001b 312e342e ffc3003c ...D...3.4.1<... 00000200: ffffffff 0bd4ffff 7490591a 01000608 .........Y.t.... 00000210: 04060008 0bd40200 7490591a a90aa8c0 .........Y.t.... 00000220: ffffffff a8c0ffff 0000010a 00000000 ................ 00000230: 00000000 00000000 00000000 ffc3003c ............<... 00000240: ffffffff c000ffff 116d95ca 00450008 ..........m...E. 00000250: d3b52600 11400040 a8c023ba ffff280a .&..@.@..#...(.. 00000260: 46e0ffff 12002ffd be002fd9 a8c042ac ...F./.../...B.. 00000270: 8206280a 00000000 00000000 ffc3003c .(..........<... 00000280: eb4cae8c 973c831f 2b08590e 01000608 ..L...<..Y.+.... 00000290: 04060008 973c0200 2b08590e 370aa8c0 ......<..Y.+...7 000002a0: eb4cae8c a8c0831f 0000780a 00000000 ..L......x...... 000002b0: 00000000 00000000 00000000 ............ eth1: asix_rx_fixup() Bad Header Length 0xffffffc3, offset 4 00000000: ff4600b9 ffffffff 2a80ffff 8d6aeaa8 ..F........*..j. 00000010: 00450008 0000ab00 11400040 a8c0986f ..E.....@.@.o... 00000020: ffff020a c5b9ffff 97001127 0602c13c ........'...<... 00000030: 00028b00 a82a800a c08d6aea 01020aa8 ......*..j...... 00000040: 2a800600 8d6aeaa8 0004000a 0b34c113 ...*..j.......4. 00000050: 42550400 000c544e 325a4203 42220003 ..UBNT...BZ2.."B 00000060: 72612e5a 30343237 2e33762e 35352e37 Z.ar7240.v3.7.55 00000070: 3033362e 37312e38 33313430 3535312e .6308.170413.155 00000080: 0b001636 2e372e33 362e3535 15383033 6...3.7.55.6308. 00000090: 5a420300 01001732 01001800 01001900 ..BZ2........... 000000a0: 01001a00 06001300 eaa82a80 00128d6a .........*..j... 000000b0: f8010004 05001bf0 2e342e32 16364434 ........2.4.4D 00000000: ffc3003c ffffffff 2a80ffff a88bb2a8 <..........*.... 00000010: 01000608 04060008 2a800100 a88bb2a8 ...........*.... 00000020: 050aa8c0 00000000 a8c00000 00006d0a .............m.. 00000030: 00000000 00000000 00000000 00000000 ................
