[dpdk-dev] [PATCH 2/3] examples/l3fwd: fix build without SSE4.1

[Thomas Monjalon]

clang reports this error:
examples/l3fwd/main.c:550:1: error: unused function 'send_packetsx4'
The function is used only when ENABLE_MULTI_BUFFER_OPTIMIZE is 1.

Fixes: 96ff445371e0 ("examples/l3fwd: reorganise and optimize LPM code path")
Fixes: 6f1c1e28d98e ("examples/l3fwd: fix build with exact-match enabled")
