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.
I'll take a look at this.

Thx , I wonder that there are some bugs in the rtl8139 driver.
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.
