Subject: [PATCH bpf v2] selftests: bpf: fix compiler warning
Date: Tue, 28 May 2019 19:02:18 +0000	[thread overview]
Message-ID: <20190528190218.GA6950@ip-172-31-44-144.us-west-2.compute.internal> (raw)

Add missing header file following compiler warning

prog_tests/flow_dissector.c: In function ‘tx_tap’:
prog_tests/flow_dissector.c:175:9: warning: implicit declaration of function ‘writev’; did you mean ‘write’? [-Wimplicit-function-declaration]
  return writev(fd, iov, ARRAY_SIZE(iov));
         ^~~~~~
         write

Fixes: 0905beec9f52 ("selftests/bpf: run flow dissector tests in skb-less mode")
