Hi, This adds support for BPF-JIT for MIPS. Tested on mips32 LE/BE and mips64 BE with a few networking tools such as tcpdump and dhcp but not all opcodes have been tested as far as I can tell. There are a few optimizations left to be made (fastpath for load operations instead of calling the helper functions) but these can be added later on. If someone has complex network setups in place and would like to give it a try, that would be much appreciated.
