K 10 svn:author V 6 dteske K 8 svn:date V 27 2013-11-22T00:32:32.738459Z K 7 svn:log V 597 Improve network device scanning in the netdev module. First, make it use the `device.subr' framework (improving performane and reducing sub-shells). Next improve the `device.subr' framework itself. Make use of the `flags' device struct member for network interfaces to indicate if an interface is Active, Wired Ethernet, or 802.11 Wireless. Functions have been added to make checks against the `flags' bit-field quick and efficient. Last, add function for rescanning the network to update the device registers. Remove an unnecessary local (ifn) while we're here (use already provided local `if'). END
