iavf: Fix handling of dummy receive descriptors
Summary
iavf: Fix handling of dummy receive descriptors
Original description
The description as published by the source.
In the Linux kernel, the following vulnerability has been resolved:
iavf: Fix handling of dummy receive descriptors
Fix memory leak caused by not handling dummy receive descriptor properly.
iavf_get_rx_buffer now sets the rx_buffer return value for dummy receive
descriptors. Without this patch, when the hardware writes a dummy
descriptor, iavf would not free the page allocated for the previous receive
buffer. This is an unlikely event but can still happen.
