Actually, the module parameters are the same as the Linux driver, so, they are documented in Documentation/networking/e1000e.txt in the Linux kernel sources, here for instance: https://git.xenomai.org/ipipe.git/tree/Documentation/networking/e1000e.txt?id=v4.2-rc1 (beware that the driver versions are not the same, so, there may be some differences, like default values, or even some options, but modinfo will tell you that). Your problem is probably that you should disable interrupt throttling passing InterruptThrottleRate=0. -- Gilles. https://click-hack.org _______________________________________________ Xenomai mailing list Xenomai@xenomai.org http://xenomai.org/mailman/listinfo/xenomai
