From f7f26e5b328617ae6527fa05e4cb7ab23a283045 Mon Sep 17 00:00:00 2001 From: Alok Mishra Date: Fri, 26 Apr 2024 15:45:49 +0530 Subject: octeon: add support for max_rx_frame_size update This patch adds capability to update max_rx_frame_size on octeon port. Initial MTU value is being set in the "oct_port_start", which is invoked every time the Ethernet interface is brought up, thus overwriting any MTU value set by VPP CLI. Moved the MTU initialization to "oct_port_init" to address this.
