From 7d0bc2602308ec0a183241914b0646d99d0fb541 Mon Sep 17 00:00:00 2001 From: Li Zetao Date: Tue, 8 Aug 2023 19:45:02 +0800 Subject: [PATCH] octeontx2-af: Remove redundant functions mac2u64() and cfg2mac() The mac2u64() is used to convert an Ethernet MAC address into a u64 value, as this is exactly what ether_addr_to_u64() does. Similarly, the cfg2mac() is also the case. Use ether_addr_to_u64() and u64_to_ether_addr() instead of these two.
