For example, forward tcp traffic to veth0 and set
destination mac address to 11:22:33:44:55:66 :
$ tc filter add dev enp0s9 protocol ip parent ffff: \
flower \
ip_proto tcp \
action pedit ex munge \
eth dst set 11:22:33:44:55:66 \
action mirred egress \
redirect dev veth0

Utilize the extended pedit netlink to set an offset relative to a
specific header type. Old netlink only enabled the user to set
approximated offset relative to the IPv4 header.
To use this extended functionality need to use the 'ex' keyword after
'pedit' and before any 'munge'.
e.g:
$ tc filter add dev ens9 protocol ip parent ffff: \
flower \
ip_proto udp \
dst_port 80 \
action pedit ex munge \
ip dst set 1.1.1.1 \
pipe \
action mirred egress redirect dev veth0
