Looks like, "ifdi_promisc_set" routine of the driver is not getting
triggered properly.  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.
