Jesper Dangaard Brouer cf5beb8ce9 samples/bpf: xdp1 and xdp2 reduce XDPBUFSIZE to 60
[ Upstream commit 60548b825b ]

Default samples/pktgen scripts send 60 byte packets as hardware adds
4-bytes FCS checksum, which fulfils minimum Ethernet 64 bytes frame
size.

XDP layer will not necessary have access to the 4-bytes FCS checksum.

This leads to bpf_xdp_load_bytes() failing as it tries to copy 64-bytes
from an XDP packet that only have 60-bytes available.
