Hello. I'm trying to modify packets within the BPF program and send them to another IP address through the same NIC with the XDP_TX call (ultimately I'm trying to do a RTP proxy sample). What I'm missing is the MAC address for the IP, which can be normally obtained from the ARP table. I can see two solutions for dynamic sending: -search the kernel tables for ARP entries, -produce ARP reqests and have own ARP table. Is any of the solutions possible with the current implementation? Is there any better solution? Kind regards, Tomaz
