Once that's working suffiently well, I could make it into a stand-alone driver, or see if it can be integrated into Aleksandrs work. Either I'm doing something wrong, or the RTL8366 is working a lot differently from the datasheet. I've put the source as well as a binary up for download; could someone with a running WR1043 run the command and post the results here? http://www.lassitu.de/freebsd/rtl.tbz Here's my output directly after reboot: # ./rtl -D 00 0830 0000 0000 0000 00b0 2805 0000 0000 08 0000 0f45 83ed 0101 0000 0200 0000 0001 10 ffff ffff ffff ffff 7660 6060 fe76 6060 18 0000 0000 0000 0000 0000 0000 0000 0000 20 0001 ffff 0000 0002 0000 0000 0003 0000 28 0000 0004 0000 0000 0005 0000 0000 0006 30 0000 0000 0007 0000 0000 0008 0000 0000 38 0009 0000 0000 000a 0000 0000 000b 0000 40 0000 000c 0000 0000 000d 0000 0000 000e 48 0000 0000 000f 0000 0000 0010 0000 0000 50 ffff ffff ffff ffff ffff ffff ffff ffff 58 0000 0000 0000 0000 5937 0000 0000 0000 60 0000 0000 0000 0000 0000 0000 0000 0000 68 0000 0000 0000 0000 0000 0000 0000 0000 70 0000 0000 0000 0000 0000 0000 0000 0000 78 0000 0000 0000 0000 0000 0000 0000 0000 # ./rtl -v VTCR0[0] EN_VLAN = enabled VTCR0[1] VLAN_TAG_AWARE = disabled VTCR0[2] VLAN_TAG_ADMIT = enabled VTCR0[3] EN_INGRESS_RULE = disabled VTCR0[4] EN_UC_LEAKY = disabled VTCR0[5] EN_ARP_LEAKY = disabled VTCR0[6] EN_IPMC_LEAKY = disabled VTCR0[12] EN_TG_DROP = disabled WAN 1 2 3 4 CPU Tagging keep keep keep keep keep keep 00= 3702 - - - - - * 01= 0 - - - - - - 02= 0 - - - - - - 03= 0 - - - - - - 04= 0 - - - - - - 05= 1 * * * * * * 06= 0 - * - - - - 07= 0 - - - - - - 08= 3 - - - - - - 09= 0 - - * - - - 10= 0 - - - - - - 11= 5 - - - - - - 12= 0 - * * - - - 13= 0 - - - - - - 14= 7 - - - - - - 15= 0 - - - * - - Stefan -- Stefan Bethke <stb@lassitu.de> Fon +49 151 14070811
