[ Upstream commit 24720d7452df2dff2e539d9dff28904e25bb1c6d ]
This patch added the data checksum error mib counters check for the script mptcp_connect.sh when the data checksum is enabled.
In do_transfer(), got the mib counters twice, before and after running the mptcp_connect commands. The latter minus the former is the actual number of the data checksum mib counter.
The output looks like this:
ns1 MPTCP -> ns2 (dead:beef:1::2:10007) MPTCP (duration 86ms) [ OK ] ns1 MPTCP -> ns2 (10.0.2.1:10008 ) MPTCP (duration 66ms) [ FAIL ] server got 1 data checksum error[s]
