However,
Another clarification: the rteth* devices that the _standard_ ifconfig list are created by RTcap for pure capturing purposes. What rtifconfig lists is more important (though there can be no pseudo rtethX under Linux without a proper rtethX on the real-time side). > in order to get all interfaces up I have to us the command > > # insmod /usr/local/rtnet/modules/rt_e1000.ko > InterruptThrottleRate=0,0,0,0,0,0 RxIntDelay=200,200,200,200,200,200 > RxAbsIntDelay=750,750,750,750,750,750 XsumRX=1,1,1,1,1,1 > TxIntDelay=0,0,0,0,0,0 TxAbsIntDelay=0,0,0,0,0,0 cards=1,1,1,1,1,1 > > which has 6 instead of just 5 values for each parameter.

Yes, if you set some field in the cards array to 0, the corresponding device is skipped by rt_e1000 on initialization (and left for Linux). But if you load rt_e1000 manually and without any parameters, it should find all devices. > > about the last issue with the configure.
