Haiyang Zhang 184367dce4 hv_netvsc: Fix XDP refcnt for synthetic and VF NICs ... The caller of XDP_SETUP_PROG has already incremented refcnt in __bpf_prog_get(), so drivers should only increment refcnt by num_queues - 1. To fix the issue, update netvsc_xdp_set() to add the correct number to refcnt. Hold a refcnt in netvsc_xdp_set()’s other caller, netvsc_attach(). And, do the same in netvsc_vf_setxdp(). Otherwise, every time when VF is removed and added from the host side, the refcnt will be decreased by one, which may cause page fault when unloading xdp program.
