From 685920920e3d5f68a8c50107b97747b0f8ce050f Mon Sep 17 00:00:00 2001 From: Shradha Gupta Date: Sun, 16 Feb 2025 19:42:42 -0800 Subject: hv_netvsc: Use VF's tso_max_size value when data path is VF On Azure, increasing VF's gso/gro packet size to up-to GSO_MAX_SIZE is not possible without allowing the same for netvsc NIC (as the NICs are bonded together). For bonded NICs, the min of the max aggregated pkt size of the members is propagated in the stack. Therefore, we use netif_set_tso_max_size() to set max aggregated pkt size to VF's packet size for netvsc too, when the data path is switched over to the VF Tested on azure env with Accelerated Networking enabled and disabled.
