109 ↗	(On Diff #135794)	Is this bit supposed to be here? Looks like it's some routing table index, not an address family?

109 ↗	(On Diff #135794)	AFAIU, the (int)-1 returned by linux_to_bsd_domain() would convert into 255 when assigned to (unsigned char)rtm->rtm_table. Thus, 254 seems like a typo to me. I can separate that into a single commit.
