From 5827fe2bc9c4bade6af994676c9823908e091877 Mon Sep 17 00:00:00 2001 From: Shinas Rasheed Date: Tue, 14 Nov 2023 05:45:32 -0800 Subject: [PATCH] octeon_ep: add padding for small packets Pad small packets to ETH_ZLEN before transmit, as hardware cannot pad and requires software padding to ensure minimum ethernet frame length.
