[zdsldsm]

Hello, As shown in the error message below, when I try to load the xdpdump_xdp.o, I will be prompted that the permission is not allowed, but I can load some files normally, such as xdpfilt_ alw_ all.o. I think it may involve memory copy. Could you pleasw give me some suggesstions? How do you get the data packets' payload in xdp? Thank you!

sudo ./xdp-loader load -m skb ens33 xdpdump_xdp.o
Couldn't attach XDP program on iface 'ens33': Permission denied(-13)

Is this still an issue on the current master? If so, please include the debug log out output of that load command (add -vv)
