Hi ,
    I'm using bpf to send and receive the EtherCat frame,but there are something strange than when I send a broadcast 
ECAT frame and this frame is less then 60 bytes,I can't receive the frame form the slave, but I add a command 'nop' to 
fill the frame size over 60 bytes ,I can receive from slave. I am using QNX6.5 and the ethernet card rtl8139. And also 
when I use rtl8169,there is no problem like this.

Re: EtherCat Problem

Re: EtherCat Problem

Can you ping another machine with "ping -s40 ip.address"? If not, please
post the output from "pci -v" on your machine with the 8139 controller.
