From 26c4e7ca72d970d120f0f51244bc8d37458512a0 Mon Sep 17 00:00:00 2001 From: Vladislav Yasevich Date: Tue, 1 Sep 2015 11:26:46 -0400 Subject: [PATCH] rtl8139: Do not consume the packet during overflow in standard mode. When operation in standard mode, we currently return the size of packet during buffer overflow. This consumes the overflow packet. Return 0 instead so we can re-process the overflow packet when we have room. This fixes issues with lost/dropped fragments of large messages.
