Since we change these macros, we might as well avoid triggering complaints from checkpatch because of mixed case. old=RTE_IPv4 new=RTE_IPV4 git grep -lw $old | xargs sed -i -e "s/\<$old\>/$new/g" old=RTE_ETHER_TYPE_IPv4 new=RTE_ETHER_TYPE_IPV4 git grep -lw $old | xargs sed -i -e "s/\<$old\>/$new/g" old=RTE_ETHER_TYPE_IPv6 new=RTE_ETHER_TYPE_IPV6 git grep -lw $old | xargs sed -i -e "s/\<$old\>/$new/g" Signed-off-by: David Marchand <david.marchand@redhat.com> Reviewed-by: Olivier Matz <olivier.matz@6wind.com>
