Your card is discovered as card=0x360c1462, mine as card=0xe0001458. I
think yours is really a 8168/8111B, while mine is a 8111C.
Accroding to the followling line in /sys/dev/re/if_re.c, re_attach(dev),
hwrev = CSR_READ_4(sc, RL_TXCFG) & RL_TXCFG_HWREV;
and the definition in /sys/pci/if_rlreg.h,
#define RL_TXCFG_HWREV 0x7CC00000
I traced a debug kernel and found that
CSR_READ_4(sc, RL_TXCFG)
for my card is
0x3f2000c0
so the masked hwrev should be
0x3c000000
I added this line in /sys/pci/if_rlreg.h,
#define RL_HWREV_8111C 0x3c000000
and these lines to the table in /sys/dev/re/if_re.c,
{ RT_VENDORID, RT_DEVICEID_8168, RL_HWREV_8111C,
"RealTek 8111C Single-Chip PCIe Gigabit Ethernet" },
and these to the table in the same .c.
{ RL_HWREV_8111C, RL_8169, "8111C"},
After reboot, re(4) successfully recognized the chip. However, it
failed with the following error:
re0: MII without any phy!
I traced the mii_phy_probe() function in /sys/dev/mii/mii.c, only to
find all the bmsr values read by MIIBUS_READREG was:
0, 0xffff, 0, 0, ... (all 0's)
so that mii_phy_probe() did not find any PHY.
What's the problem?
