Revision 9f9f0f19994b42b3e5e8735d41b9c5136828a76c authored by Yunsheng Lin on 19 October 2021, 14:16:32 UTC, committed by David S. Miller on 20 October 2021, 10:38:11 UTC
rx unused desc is the desc that need attatching new buffer
before refilling to hw to receive new packet, the number of
desc need attatching new buffer is calculated using next_to_use
and next_to_clean. when next_to_use == next_to_clean, currently
hns3 driver assumes that all the desc has the buffer attatched,
but 'next_to_use == next_to_clean' also means all the desc need
attatching new buffer if hw has comsumed all the desc and the
driver has not attatched any buffer to the desc yet.

This patch adds 'refill' in desc_cb to indicate whether a new
buffer has been refilled to a desc.
