From: Ariel Levkovich Date: Mon, 29 Aug 2022 21:32:30 +0000 (+0300) Subject: net/mlx5e: TC, Keep mod hdr actions after mod hdr alloc X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=5e72f3f1c558019082cfeedeed73748f35d780c6;p=linux.git net/mlx5e: TC, Keep mod hdr actions after mod hdr alloc When offloading TC NIC rule which has mod_hdr action, the mod_hdr actions list is freed upon mod_hdr allocation. In the new format of handling multi table actions and CT in particular, the mod_hdr actions list is still relevant when setting the pre and post rules and therefore, freeing the list may cause adding rules which don't set the FTE_ID. Therefore, the mod_hdr actions list needs to be kept for the pre/post flows as well and should be left for these handler to be freed.
