Forcibly setting the promisc mode from driver is solving the packet drop issue. Now I see the ARP reply packet. axgbe has split header support, which causes trouble starting from ping packets due to incompatibility with Iflib/Netmap and associated utilities. I made some changes to the driver, Iflib and Netmap utilities and having the netmap bridge working with axgbe now. I am working on a clean fix for promisc mode setting and incompatibility issue. Will submit the changes for review once done. Thanks for your inputs and support. Done in r367920. > Thank you. Thanks, Rajesh.
