KNI ratelimit default value.
The total speed limit for a single process entering the kni ring is 10,000 QPS,
1000 QPS for general packets, 9000 QPS for console packets (ospf/arp, etc.)
The total speed limit for kni forwarding to the kernel is 20,000 QPS.
1. Automatic configuration of multi vlan vip(IPv4 and IPv6).
1.1 And support automatic multi default route for per vlan, via different fib num.
1.2 IPv6 not support set multi route fib now, just use RT_DEFAULT_FIB, And you can set multi fib use tool 'ff_route'.
1.3 If vlan_flag is true, all port's addrs/vips will not to set, just create the iface.
2. Automatic configuration of simple policy routing.
2.1 Only supports the simplest policy routing settings, like:
`ff_ipfw -P 0 add 100 setfib 0 ip from 125.94.59.0/24 to any out`
`from 125.94.59.0/24` need set addr is '125.94.59.0', netmask is '255.255.255.0'
2.2 IPv6 does not support automatic configuration of policy routing. If ipv6 policy routing is required, you still need to use ff_ipfw to manually configure it.
GCC began to offer full support for the C11 standard starting with version 4.9,
including support for the _Atomic keyword.
https://gcc.gnu.org/gcc-4.9/changes.html
Since GCC 14 now implements `__has_extension()` the build started to use
Clang atomics, i.e. the `__c11_*` APIs only provided by Clang.
Fix build to use GNUC atomics and include the upstream patch:
https://reviews.freebsd.org/D16585
which enables C11 atomics when building with GCC >= 4.7.
1. Added F-Stack FreeBSD support. see 9f7a1423a0 .
2. Enable INET6 by default in helloworld. see 51c91ab0ad .
3. Added FDIR support. see 4854315d0d .
4. To avoid compiling errors when gcc version >= 10. see 6daadb0b5c .
5. Modify `struct linux_sockaddr` same to `struct sockaddr` in linux. see d96a9d10f4 .
6. Sync some modified of ff_config.c, inclue set dpdk log level, Avoid memory leaks, suppor vip_addr and vip_addr6, etc. see git log lib/ff_config.c in branch of dev.
7. Sync some modified of ff_syscall_wrapper.c, include ff_sendmsg, ff_recvmsg, ip6_opt_convert, etc. see git log lib/ff_syscall_wrapper.c in branch of dev.
8. The CPU usage of packet_dispatcher() is modified to usr. see 0508c8b8ec .
9. If process_dispatch_ring() has data packet to be processed and it is considered non-idle state. see 81dd6c7a24 .
10. Fix a plurality of packets may not statistics in ff_traffic.rx_packets and ff_traffic.rx_bytes. see 0b4a084c8a .
11. Added FF_IPSEC=1 in lib/Makefile, disable by default.
12. Some other modified.
