CVE: NA

----------------------------------------

The member variable ndo_xdp_get_xmit_slave is added to the struct
net_device_ops in commit 879af96f("net, core: Add support for XDP
redirection to slave device"). As a result, the kabi is changed. It is
need to use the reserved KABI_RESERVE to rectify the fault.
