base-files: add macaddr_canonicalize helper function
In commit r38690, the MAC address canonicalization has been converted to use 'tr' instead of 'printf'. This only works if with MAC addresses which uses the 'xx:xx:xx:xx:xx:xx' format. However on some boards, the MAC addresses are stored in different format in the mtd partition. Some vendors are using hyphens or dots as separators instead of colons. Also the leading zeroes may be missing from the individual octets or those are replaced with spaces. Add a new function which can be used to convert these into the 'xx:xx:xx:xx:xx:xx' format. Also update the 'mtd_get_mac_ascii' function to use the new helper. The helper function is based on this code: http://isquared.nl/blog/2010/08/11/Bash-function-to-canonicalize-MAC-addresses/ Signed-off-by: Gabor Juhos <juhosg@openwrt.org> git-svn-id: svn://svn.openwrt.org/openwrt/trunk@38803 3c298f89-4303-0410-b956-a3cf2f4a3e73
