Hi Team,

I am debugging upcall processing in ofproto-dpif-upcall.c  file . I am not able to visualize how opfbuf structure is being
filled with actions(Note: My bridge is configured without OF rules, meaning actions=NORMAL).
I could see packet is being flooded for unknown mac, vlan in the code. But somehow dpif_netlink_operate is receiving proper netlink action
attributes in sequence to be executed in DP.
Also I could see in gdb xout.odp_actions is only holding some addresses. How to know what actually resides in this address.
(gdb) p upcall->xout.odp_actions->data
$7 = (void *) 0x7f6275a53398

Could someone please , let me know  how this buffer is being filled, and what is the importance of ofpbuf.

Thanks in Advance,
Uday
