From e7a58fc71ca039ae46590e9395467cea283d259c Mon Sep 17 00:00:00 2001 From: Mark Cave-Ayland Date: Fri, 15 Dec 2017 18:41:54 +0000 Subject: rtl8139: 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.
