Is 280 used in other OS? Just curious as why not using 273
All these definitions (PF_*, AF_*, ARPHRD_* ) are operation system
specific (that's why you find it in /usr/include/linux/*.h :)
I just googled for AF_INET and found that e.g.
AF_APPLETALK is "16" in winsock.h and "5" in include/linux/socket.h
The reason to use 280 instead of 273 was, that all the 27x stuff was
dedicated to the X.25 domain. So to start with a new 280 looked
reasonable to me.
At the end of the ARPHRD_* definitions there's currently many 'change
traffic' due to IEEE80211.
