Hi, In an ethernet driver, I am reading the mac address from the device and assigning the dev_addr field of a net_device structure. The dev_addr[0] field is assigned the lowest byte and dev_addr[5] is assigned the highest byte of the address. This setup works fine. For example I can get an IP address via dhcp, and the dhcp server knows the address as in high[5]:[4]:[3]:[2]:[1]:[0]low order. The problem is when I type ifconfig, I see the mac address in the reverse order of what it should look like, i.e. high[0]:[1]:[2]:[3]:[4]:[5]low. I first thought I had wrong assignment in dev_addr, so reversed the order, e.g. dev_addr[0] having the highest and dev_addr[5] having the lowest byte. Then dhcp fails because it's not a right address. Perhaps the kernel's order is reverse of what the device thinks? I think the anomaly in ifconfig's output can't be fixed because eth_type_trans() compares the ethernet header with dev_addr, if dev_addr is in the order ifconfig expects, compare_ether_addr() will never match the order in real header with dev_addr. What do you think? Thanks, Bahadir -- Kernelnewbies: Help each other learn about the Linux kernel. Archive: http://mail.nl.linux.org/kernelnewbies/ FAQ: http://kernelnewbies.org/faq/
