From 03ab7461df3c74c9418c3f5485ea1127ece1ff79 Mon Sep 17 00:00:00 2001 From: Jiri Pinkava Date: Sun, 20 Jun 2010 20:05:52 +0200 Subject: [PATCH] USB: gadget eth: Fix calculate CRC32 in EEM CRC should be calculated for Ethernet frame, not for whole recievede EEM data. This bug shows rarely, because in many times len == skb->len.
