Subject: selftests: correct define in msg_zerocopy.c
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=bbd9644e84f68587ed136c7e1c56e454c26231ff;p=openwrt%2Fstaging%2Fblogic.git

selftests: correct define in msg_zerocopy.c

The msg_zerocopy test defines SO_ZEROCOPY if necessary, but its value
is inconsistent with the one in asm-generic.h. Correct that.

Also convert one error to a warning. When the test is complete, report
throughput and close cleanly even if the process did not wait for all
completions.
