Hi,then I must have 2 Ethernet lines.

Pushing this FAQ into the wiki would be highly appreciated. :)
I've pasted in a part of a script that I used to start rtnet with more than one card at some stage. Adapt accordingly. Its a bit messy I concede but there is some history on this list about this too.#NIC modules #insmod /usr/local/rtnet/modules/rt_via-rhine.ko#insmod /usr/local/rtnet/modules/rt_e1000.ko #cards=1 #,0,0 # 0,1,0 means use the middle (eth1) card. 1,0,0= use eth0 etc insmod /usr/local/rtnet/modules/rt_8139too.ko #cards=1 #,0,0 # 0,1,0 means use the middle (eth1) card. 1,0,0= use eth0 etc (Only required if all NICS use the same driver) otherwise the other NICs remain unaffected if their driver is not unloaded.#insmod /usr/local/rtnet/modules/rt_eepro100.ko #insmod /usr/local/rtnet/modules/rt_natsemi.koDoes RTnet 8139too driver handle collisions ?Someone else might be able to answer this.
Collisions (when using hubs), queue congestions and other overload scenarios are not handled by any driver directly, that is the job of the RTmac medium access control discipline (typically: TDMA). The driver's job is to get the data onto or out of the medium as fast and as jitter-free as possible.
