From: Tony Ambardar tony.ambardar@gmail.com
[ Upstream commit 4c329b99ef9c118343379bde9f97e8ce5cac9fc9 ]
The GNU version of 'struct tcphdr', with members 'doff' and 'urg_ptr', is not exposed by musl headers unless _GNU_SOURCE is defined.
Add this definition to fix errors seen compiling for mips64el/musl-libc:
parse_tcp_hdr_opt.c:18:21: error: 'struct tcphdr' has no member named 'urg_ptr' 18 | .pk6_v6.tcp.urg_ptr = 123, | ^~~~~~~ parse_tcp_hdr_opt.c:19:21: error: 'struct tcphdr' has no member named 'doff' 19 | .pk6_v6.tcp.doff = 9, /* 16 bytes of options */ | ^~~~
