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. Type: fix Change-Id: I332d69ab22242b3443a0baca6e5dd86349a54765 Signed-off-by: Elias Rudberg <elias.rudberg@bahnhof.net> (cherry picked from commit e5ecf3ea4b456afb710f4ed903cd7e4c1ae87859)
