2022-05-22hinic: Avoid some over memory allocationChristophe JAILLET1-1/+1
'prod_idx' (atomic_t) is larger than 'shadow_idx' (u16), so some memory is over-allocated. Fixes: b15a9f37be2b ("net-next/hinic: Add wq") Signed-off-by: Christophe JAILLET <christophe.jaillet@wanadoo.fr> Signed-off-by: David S. Miller <davem@davemloft.net>
2022-04-30hinic: fix bug of wq out of bound accessQiao Ma1-2/+5
If wq has only one page, we need to check wqe rolling over page by compare end_idx and curr_idx, and then copy wqe to shadow wqe to avoid out of bound access. This work has been done in hinic_get_wqe, but missed for hinic_read_wqe. This patch fixes it, and removes unnecessary MASKED_WQE_IDX().
