From 8e50e48f4d540dfe418b28f545267e2a65ab2f34 Mon Sep 17 00:00:00 2001 From: Elias Rudberg Date: Tue, 18 Feb 2020 12:12:25 +0100 Subject: rdma: fix bug related to ring buffer Fix a bug that caused some input packets to be dropped due to errors of the type 'ip4 length > l2 length'. The change is related to the second call to the rdma_device_input_bufs() function that happens when the end of the ring buffer is reached.
