From d00d6d005424dd2447f8b0394e945909852a4282 Mon Sep 17 00:00:00 2001 From: Mark Cave-Ayland Date: Fri, 15 Dec 2017 18:41:49 +0000 Subject: [PATCH] eepro100: 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.
