[ Upstream commit 5e4c43bcb85973243d7274e0058b6e8f5810e4f7 ]
The GNU version of 'struct tcphdr' has members 'doff', 'source' and 'dest', which are not exposed by musl libc headers unless _GNU_SOURCE is defined.
Add this definition to fix errors seen compiling for mips64el/musl-libc:
flow_dissector.c:118:30: error: 'struct tcphdr' has no member named 'doff' 118 | .tcp.doff = 5, | ^~~~ flow_dissector.c:119:30: error: 'struct tcphdr' has no member named 'source' 119 | .tcp.source = 80, | ^~~~~~ flow_dissector.c:120:30: error: 'struct tcphdr' has no member named 'dest' 120 | .tcp.dest = 8080, | ^~~~
