Howdy! First time posting; please be gentle. :-) Environment: * DPDK 1.8.0 release * Linux kernel 3.0.3x-ish * 32-bit (yes, KNI works fine, after a few tweaks hugepage init strategy)
I'm trying to use the KNI example app with a configuration where multiple kthreads are created for a physical port. Per the user guide and code, the first such kthread is the "master", any the only one configurable; I'll refer to the additional kthread(s) as "slaves", although their relationship to the master kthread isn't discussed anywhere that I've looked thus far. # insmod rte_kni.ko kthread_mode=multiple # kni [....] --config="(0,0,1,2,3)" # ifconfig vEth0_0 10.0.0.1 netmask 255.255.255.0 >From the above: PMD-bound physical port0. Rx/Tx on cores 0 and 1, respectively. Master thread on core 2, one slave kthread on core 3. Upon startup, KNI devices vEth0_0 (master) and vEth0_1 (slave) are created. After ifconfig, vEth0_0 works fine; by design, vEth0_1 cannot be configured. The problem I'm encountering is that the subset of packets hitting vEth0_1 are being dropped... somewhere. They're definitely getting as far as the call to netif_rx(skb). I'll try on a newer system for comparison. But before I go too much further, I'd like to establish the correct set-up and expectations. Should I be bonding vEth0_0 and vEth0_1? Because I tried doing so (via sysfs); however, attempts to add either as slaves to bond0 were ignored. Any ideas appreciated. (Though it may end up being a moot point, with the other work this past week on KNI performance.)
