From 4227be63f081e939ae7313b1921d8f60a5d8d714 Mon Sep 17 00:00:00 2001 From: Mark Cave-Ayland Date: Fri, 15 Dec 2017 18:41:52 +0000 Subject: ftgmac100: use inline net_crc32() and bitshift instead of compute_mcast_idx() This makes it much easier to compare the multicast CRC calculation endian and bitshift against the Linux driver implementation.
