Hello, This will seem a bit off the wall, but I just noticed a discrepancy between the registers defined in the pci/if_rlreg.h directory and those specified on the RealTek datasheets for the antique RealTek 8139. In particular, as defined in the header, the registers in question are: #define RL_CFG0 0x0051 /* config register #0 */ #define RL_CFG1 0x0052 /* config register #1 */ #define RL_CFG2 0x0053 /* config register #2 */ #define RL_CFG3 0x0054 /* config register #3 */ #define RL_CFG4 0x0055 /* config register #4 */ #define RL_CFG5 0x0056 /* config register #5 */ The RealTek data sheets for the 8139, however, all indicate that these should be set to something like this: #define RL_CFG0 0x0051 /* config register #0 */ #define RL_CFG1 0x0052 /* config register #1 */ // No Config2 #define RL_CFG3 0x0059 /* config register #3 */ #define RL_CFG4 0x005A /* config register #4 */ #define RL_CFG5 0x00D8 /* config register #5 */ The datasheets I'm referencing are available here: http://realtek.info/pdf/ Specifically: http://realtek.info/pdf/rtl8139d.pdf http://realtek.info/pdf/rtl8139cp.pdf I believe the registers currently used apply to the 8169, but not necessarily the 8139 family -- can someone, hopefully easily, verify that the 8139 driver is using the right registers? The 8139 series may need the slightly different values used above to enable functionality like wake-on-lan. Thanks and regards, Matt
