Hi!
"ip_tos" (ipv4) and "Traffic Class" (ipv6) field in the header of ip packet
may contain a DSCP and ECN.
"iptos" and "ipprecedence" options in ipfw does not allow to use these
fields in the header of packets.
May want to add two additional options for working with them in the ipv4 and
ipv6 pa
I am writing a netgraph node for processing UDP packets passing through the
router / bridge.
Node must fully inspect the entire contents of the package, in some cases,
change them.
Node is connected to ng_ether (lower, upper).
I was faced with the fact that all packets are processed normally, exce
The function does not allow access to data if m_flags & M_EXT size and more
MHLEN, although the data is actually available.
Why if there is no m_flags & M_PKTHDR size anyway MHLEN instead MLEN?
As an improvement, you can try to copy the data from the current m in
m_next, if m is not enough space
Hello!
The function always returns an error and remove the chain MBUF for two or
more generated on the same host.
If the pre-call m_defrag no error occurs.
This is normal behavior?
How to know in advance the maximum size for MBUF that does not cause a
failure in m_pullup?
mbuf: 0xfe0074fc06

But arp proto can be used with any other L3 proto to resolve L2 addr from L3

TCP/IP is L4 proto and it can work without IPv4 - on IPv6.

Hi!
Changes:
1. list + hash was replaced by array of hooks: its simple and faster
2. added encap setting.
"getencap" and "setencap" messages for control it:
Default = 1 (do the VLAN encapsulation)
0: no encapsulation, just:
m->m_flags |= M_VLANTAG;
m->m_pkthdr.ether_vtag = (vlan & EVL_VLID_M
net.inet.ip.fastforwarding
- double check incoming packet, if: dst = this host / multicast / contain
options
- all packets processing by one cpu core
This option is good for one cpu core routers.

Hi!
Another way for vlans is: "ng_ether + ng_vlan + ng_iface".
See in sources: VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM
I don’t see any profits with hardware PPPoE, mpd5 is fast.
For hardware NAT you can try make "closed" netgraph based interface.
Node like "ng_ether + ng_nat" = ng_hwnat, compatible

Hi, Alex!
You can make virtual NIC via netgraph.
1. ng_ether automatic attached to every physical NICs on load module.
2. connect ng_bridge to upper and lower hooks on ng_ether 3. create and
connect ng_eiface to ng_bridge and you will get new NIC ngethX with its own
MAC address and IP addrs too.
Hi!
What I need to do to include this patch to main source tree?
