MIPS: net: Add BPF JIT
This adds initial support for BPF-JIT on MIPS Tested on mips32 LE/BE and mips64 BE/n64 using dhcp, ping and various tcpdump filters. Benchmarking: Assuming the remote MIPS target uses 192.168.154.181 as its IP address, and the local host uses 192.168.154.136, the following results can be obtained using the following tcpdump filter (catches no frames) and a simple 'time ping -f -c 1000000' command. [root@(none) ~]# tcpdump -p -n -s 0 -i eth0 net 10.0.0.0/24 -d (000) ldh [12] (001) jeq #0x800 jt 2 jf 8 (002) ld [26] (003) and #0xffffff00 (004) jeq #0xa000000 jt 16 jf 5 (005) ld [30] (006) and #0xffffff00 (007) jeq #0xa000000 jt 16 jf 17 (008) jeq #0x806 jt 10 jf 9 (009) jeq #0x8035 jt 10 jf 17 (010) ld [28] (011) and #0xffffff00 (012) jeq #0xa000000 jt 16 jf 13 (013) ld [38] (014) and #0xffffff00 (015) jeq #0xa000000 jt 16 jf 17 (016) ret #65535 - BPF-JIT Disabled real 1m38.005s user 0m1.510s sys 0m6.710s - BPF-JIT Enabled real 1m35.215s user 0m1.200s sys 0m4.140s [ralf@linux-mips.org: Resolved conflict.] Signed-off-by: Markos Chandras <markos.chandras@imgtec.com>
