I have a small test running where traffic from the NIC is forwarded onto KNI, and vice versa. This works without an issue. However, if I try to set up a bond using these interfaces using the Linux kernel itself (not the bonding PMD that DPDK provides) then on the router side, the interface is marked as LACP-BLOCKED. Does anyone have any idea as to why this may be happening? Running tcpdump on the KNI shows that the LACP packets are indeed being forwarded into the kernel, but I can't see any response from the kernel. The same bond configuration works fine without DPDK's KNI. Here's a hexdump snippet of the traffic that I'm seeing come through. 01 80 C2 00 00 02 00 0C DB FA D7 91 88 09 01 01 01 14 00 01 00 0C DB FA D7 00 00 64 00 01 00 92 4F 00 00 00 02 14 00 01 00 00 00 00 00 00 00 91 00 01 00 00 78 00 00 00 03 10 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 I'm aware that the LACP driver that exists within DPDK itself can be utilized, but at this point I'm more curious as to what could be causing this behavior, and if there are any gotchas that I am inadvertently missing Many thanks in advance!
