Hi, Ruifeng
Could we go further and implement loop inside the conditional?
Like this:
if (mlx5_mr_btree_len(&rxq->mr_ctrl.cache_bh) > 1) {
for (i = 0; i < n; ++i) {
void *buf_addr = elts[i]->buf_addr;
wq[i].addr = rte_cpu_to_be_64((uintptr_t)buf_addr +
MR btree len is a constant during Rx replenish.
Moved retrieve of the value out of loop to reduce data loads.
Slight performance uplift was measured on N1SDP.
