From 597b8af58bb2df443ebbdbdc4eef297f5d79d356 Mon Sep 17 00:00:00 2001 From: Piotr Raczynski Date: Tue, 20 Aug 2024 08:57:46 +0200 Subject: ice: add new VSI type for subfunctions Add required plumbing for new VSI type dedicated to devlink subfunctions. Make sure that the vsi is properly configured and destroyed. Also allow loading XDP and AF_XDP sockets. The first implementation of devlink subfunctions supports only one Tx/Rx queue pair per given subfunction.
