netfilter: ipt_LOG/ip6t_LOG: add option to print decoded MAC header
The LOG targets print the entire MAC header as one long string, which is not readable very well: IN=eth0 OUT= MAC=00:15:f2:24:91:f8:00:1b:24:dc:61:e6:08:00 ... Add an option to decode known header formats (currently just ARPHRD_ETHER devices) in their individual fields: IN=eth0 OUT= MACSRC=00:1b:24:dc:61:e6 MACDST=00:15:f2:24:91:f8 MACPROTO=0800 ... IN=eth0 OUT= MACSRC=00:1b:24:dc:61:e6 MACDST=00:15:f2:24:91:f8 MACPROTO=86dd ... The option needs to be explicitly enabled by userspace to avoid breaking existing parsers.
