From 1ddf1636e0e058adf2231486da0419243eb49539 Mon Sep 17 00:00:00 2001 From: Tariq Toukan Date: Mon, 22 Sep 2025 09:06:30 +0300 Subject: [PATCH] net/mlx5: Add IFC bit for TIR/SQ order capability Before this cap, firmware requested a certain creation order between TIR objects and SQs of the same transport domain to properly support the self loopback prevention feature. If order is not preserved, explicit modify_tir operations are necessary after the opening of the SQs. When set, this cap bit indicates that this firmware requirement / limitation no longer holds.
