The valgrind-3.11 does not support bpf syscall wrapper, so
makce check-afxdp-valgrind always fails, 

 |netdev_afxdp|ERR|xsk_socket__create failed (Function not implemented) mode: 
SKB qid: 0
 |netdev_afxdp|ERR|Failed to create AF_XDP socket on queue 0.

 + ovs-vsctl add-port br0 afxdp-p0
 + ovs-vsctl -- set interface afxdp-p0 options:n_rxq=1 type=afxdp 
options:xdpmode=skb
 --16877-- WARNING: unhandled amd64-linux syscall: 321
 --16877-- You may be able to write your own handler.
 --16877-- Read the file README_MISSING_SYSCALL_OR_IOCTL.
 --16877-- Nevertheless we consider this a bug.  Please report
 --16877-- it at http://valgrind.org/support/bug_reports.html.

Upgrade valgrind to 3.14+ works ok.
