[LTP] [PATCH 0/9] network: add new features

[Alexey Kodanev]

* SO_ZEROCOPY (no auto test-cases yet, can be tried manually with
  netstress 'z' option);

* IP_BIND_ADDRESS_NO_PORT, new bind_noport01 test;

* one more protocol added to netstress - UDPLITE; busy_poll03, dccp01 and
  UDP IPsec tests are updated;

* netstress server now sends data to client using send(), sendto() and
  sendmsg(), if protocol allows.

Alexey Kodanev (9):
  lib: add safe_sendmsg()
  lib: add safe_getsockopt() and tst_getsockport()
  netstress: make socketaddr returned by recvfrom() thread-local
  netstress: server: write to socket with send/sendto/sendmsg
  netstress: support UDPLITE protocol
  netstress: support SO_ZEROCOPY
  netstress: support IP_BIND_ADDRESS_NO_PORT
  network: add new test-cases with UDP LITE protocol
  network: new test-case for IP_BIND_ADDRESS_NO_PORT
