From 41d1258aceb45b45f9e68f67a9c40f0afbc09dc9 Mon Sep 17 00:00:00 2001 From: Joshua Scott Date: Tue, 6 Sep 2016 16:03:11 +1200 Subject: [PATCH] net: asix: Fix AX88772B when used with DriverModel A previous patch (net: asix: fix operation without eeprom) added a two-byte shift to the packet buffer when receiving a packet on the AX88772B. This shift was not included when the driver was updated to work with DriverModel. Testing on a Marvell DB-88F6820-ACM showed that the adapter was not functioning correctly (EHCI timeouts). This patch brings the two-byte shift to the DriverModel implementation of ops->recv (asix_eth_recv). Testing on the same board, we were able to TFTP a file over and confirm that the crc32 was correct.
