Subject: examples/tep_term: add bad Rx checksum statistics
X-Git-Tag: spdx-start~8998
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=bf7889db2615341f454c94fed6e31fc11aa3fe39;p=dpdk.git

examples/tep_term: add bad Rx checksum statistics

Add the bad Rx checksum statistics of inner IP and L4.

The number of packets with bad RX IP and L4 checksum in inner header is recorded.
