ethtool reports the same

this war kernel 2.6.17.14 and the driver was compiled as a module.


with kernel 2.6.20.4(and build in e1000 driver):

Intel(R) Xeon(TM) CPU 3.00GHz GenuineIntel GNU/Linux

the devices are recognized ok as eth0,eth1.eth2,eth3,eth4 but misnumered
and one missing int mii-tool/ethtool
