This patch fixes two lines in which the rx_offset received by the device
wasn't taken into account:
- prefetch function:
In our driver the copied data would reside in
rx_info->page + rx_headroom + rx_offset
so the prefetch function is changed accordingly.
- setting page_offset to zero for descriptors > 1:
for every descriptor but the first, the rx_offset is zero. Hence
the page_offset value should be set to rx_headroom.
The previous implementation changed the value of rx_info after
the descriptor was added to the SKB (essentially providing wrong
page offset).
