This was gleaned from conversations with Donald Becker w/regard to why: ifconfig eth1 hw ether a:b:c:d:e:f fails to work with the RTL drivers. This fixes the problem, at least on my machine: (The new line has ### in front of it..) 8139too.c, line 1229, from kernel 2.4.prerelease: /* Check that the chip has finished the reset. */ for (i = 1000; i > 0; i--) if ((RTL_R8 (ChipCmd) & CmdReset) == 0) break; /* Restore our idea of the MAC address. */ ### RTL_W8_F (Cfg9346, 0xC0); /* Fix provided by Becker */ RTL_W32_F (MAC0 + 0, cpu_to_le32 (*(u32 *) (dev->dev_addr + 0))); RTL_W32_F (MAC0 + 4, cpu_to_le32 (*(u32 *) (dev->dev_addr + 4))); The 2.2.18 driver is broken too, but I think Donald is going to send the fixes for it.
