When there is only one byte in a frag, the current calculation using "(size + HNS3_MAX_BD_SIZE - 1) >> HNS3_MAX_BD_SIZE_OFFSET" will return zero, because HNS3_MAX_BD_SIZE is 65535 and HNS3_MAX_BD_SIZE_OFFSET is 16. So it will cause tx error when a frag's size is one byte. This patch fixes it by using DIV_ROUND_UP. Fixes: 3fe13ed9 ("net: hns3: avoid mult + div op in critical data path") Signed-off-by:
