> Subject: [PATCH 1/2] app/testpmd: fix csumonly mode when run without outer
> chksum
>
> Donot use outer metadata when neither outer ip checksum nor outer udp
> checksum is enabled. PMD's will ignore the outer_l2_len and outer_l3_len in
> cases where none of the outer checksum is enabled and hence only l2_len and
> l3_len will be used to calculate the offsets for L2 or L3 header.
