23 An AF_XDP socket (XSK) is created with the normal socket()
24 syscall. Associated with each XSK are two rings: the RX ring and the
60 call and submits the XSK of the process it would like to share UMEM
61 with as well as its own newly created XSK socket. The new process will
72 user-space application can place an XSK at an arbitrary place in this
74 this map and at this point XDP validates that the XSK in that map was
78 program loaded (and one XSK in the XSKMAP) to be able to get any
79 traffic to user space through the XSK.
