As agreed in a Technical Board meeting, the preferred IRC channel for the DPDK project moved from freenode to Libera.Chat: https://mails.dpdk.org/archives/dev/2021-July/214662.html
The website is updated: https://core.dpdk.org/contribute/ There is a good guide to start with Libera.Chat: https://libera.chat/guides/connect Let's meet on Libera.Chat channel #DPDK for quick questions, synchronization, or just to say hello!
