ℹ️ Googlers: Go here for more info.
For linux 3.10, TCP_CC_INFO and SO_MEMINFO are not supported. When we define HAVE_SO_MEMINFO / HAVE_TCP_CC_INFO as 0, functions like write_tcp_bbr_cc_info and write_so_meminfo will not be accessed. So wrap them with #ifdef and #endif.
Also, for lower linux version, tcp_info option value has less fields(e.g. 120 bytes). So remove the size assert.
This commit is based on the following packetdrill upstream pull request, with a slightly tweaked commit description: https://github.com/google/packetdrill/pull/13
