Sorry for a mistake for the code, it should be:
------------------------------------------------------------------------------------------------
int n = txq->tx_rs_thresh;
int32_t i = 0, j = 0;
const int32_t k = RTE_ALIGN_FLOOR(n, RTE_I40E_TX_MAX_FREE_BUF_SZ);
const int32_t m = n % RTE_I40E_TX_MAX_FREE_BUF_SZ;
struct rte_mbuf *free[RTE_I40E_TX_MAX_FREE_BUF_SZ];
For FAST_FREE_MODE:
if (k) {
for (j = 0; j != k - RTE_I40E_TX_MAX_FREE_BUF_SZ;
j += RTE_I40E_TX_MAX_FREE_BUF_SZ) {
for (i = 0; i <RTE_I40E_TX_MAX_FREE_BUF_SZ; ++i, ++txep) {
free[i] = txep->mbuf;
txep->mbuf = NULL;
}
rte_mempool_put_bulk(free[0]->pool, (void **)free,
RTE_I40E_TX_MAX_FREE_BUF_SZ);
}
}
if (m) {
for (i = 0; i < m; ++i, ++txep) {
free[i] = txep->mbuf;
txep->mbuf = NULL;
}
}
rte_mempool_put_bulk(free[0]->pool, (void **)free, m); }
