Mechanical, hopefully non-functional changes stemming from setup_etheraddr always succeeding now that it always assigns a MAC, either from the command line or generated randomly: the test of the return of setup_etheraddr is removed, and code dependent on it succeeding is now unconditional setup_etheraddr can now be made void struct uml_net.have_mac is now always 1, so tests of it can be similarly removed, and uses of it can be replaced with 1 struct uml_net.have_mac is no longer used, so it can be removed struct uml_net_private.have_mac is copied from struct uml_net, so it is always 1 tests of uml_net_private.have_mac can be removed uml_net_private.have_mac can now be removed the only call to dev_ip_addr was removed, so it can be deleted It also turns out that setup_etheraddr is called only once, from the same file, so it can be static and its declaration removed from net_kern.h. Similarly, set_ether_mac is defined and called only from one file. Finally, setup_etheraddr and set_ether_mac were moved to avoid needing forward declarations.
