/* Copy the listen sk's HDR_OPT_CB flags to its child.
*
* During 3-Way-HandShake, the synack is usually sent from
* the listen sk with the HDR_OPT_CB flags set so that
* bpf-prog will be called to write the BPF hdr option.
*
* In fastopen, the child sk is used to send synack instead
* of the listen sk. Thus, inheriting the HDR_OPT_CB flags
* from the listen sk gives the bpf-prog a chance to write
* BPF hdr option in the synack pkt during fastopen.
*
* Both fastopen and non-fastopen child will inherit the
* HDR_OPT_CB flags to keep the bpf-prog having a consistent
* behavior when deciding to clear this cb flags (or not)
* during the PASSIVE_ESTABLISHED_CB.
*
* In the future, other cb flags could be inherited here also.
