I have been looking at the man page for pcap_set_protocol() for some time. The man page explains the function is 
a Linux-specific extension. Would it be better to rename the function to something like pcap_set_linux_protocol() 
before it is too late? The function was added to the master branch in June 2017 (libpcap pull request #595) and 
it has not made it into a libpcap release yet.

Or pcap_linux_set_protocol()/pcap_set_protocol_linux(); perhaps in cases where we add platform-specific functions, 
put the platform name after pcap_ or at the end of the name, to have a general pattern (it's too late for some of 
the Windows-specific ones, but many of them are either obsolete with generic replacements, Windows-specific 
because of inherent UN*X vs. Windows differences so it's somewhat implied, or no longer supported).

I'd rather pcap_set_protocol_linux(), because we already have functions like
pcap_activate_linux(), pcap_can_set_rfmon_linux(), pcap_cleanup_linux(), pcap_inject_linux(),
pcap_read_linux(), pcap_set_datalink_linux(), pcap_setdirection_linux(), pcap_setfilter_linux(),
pcap_stats_linux().

Alright, commit 697b1f7 does that.
