I reply to myself, because I have found some informations:
According to the Ethercat master documentation 1.5.0, section 4.2 Native EtherCat Device Drivers, I should use ec_e100 for both ethernet and ethercat trafic. Therefore I will remove the e100 from the initrd and, I will put ec_e100 instead.

Hi, I have just bought a EtherLab smart kit to evaluate EtherCAT, and now I would like to run EtherCAT master on a Linux diskless computer. But I have a problem when I start the ethercat service: the service unloads the linux driver that is required for diskless operations, and then obviously the computer hangs, because it cannot access to its NFS root filesystem. This is my question: Is it possible to run simultaneously e100 and ec_100, each of them on a different Ethernet controller ? How to do it ? More details about my configuration: The diskless computer is a VMIVME-7700. It is a VME single board computer with two Ethernet controllers intel e100. The computer boots with PXE. It downloads the linux kernel and the initrd with TFTP. The computer accesses to its NFS root filesystem through eth0 (module e100) and I would like to run the ethercat master driver (module ec_e100) on eth1. I run EtherLab stable-1.5 on Linux Debian 6.0/i386 with a linux kernel 2.6.32.11 + RTAI 3.8.1 Should I try to built statically the e100 linux driver in the kernel ? Should I try to boot the computer with the ec_e100 driver ? Thank you very much for your help.
