Note the following difference between releases 1.2 and 1.3:
-* In release 1.3, the Intel® DPDK supports two different 1 GBe drivers: igb and em.
+* In release 1.3, the Intel® DPDK supports two different 1 GbE drivers: igb and em.
Both of them are located in the same library: lib_pmd_e1000.a.
Therefore, the name of the library to link with for the igb PMD has changed from librte_pmd_igb.a to librte_pmd_e1000.a.
* The method used for managing mbufs on the NIC TX rings for the 10 GbE driver has been modified to improve performance.
As a result, different parameter values should be passed to the rte_eth_tx_queue_setup() function.
- The recommended default values are to have tx_thresh.tx_wt hresh, tx_free_thresh,
+ The recommended default values are to have tx_thresh.tx_wthresh, tx_free_thresh,
as well as the new parameter tx_rs_thresh (all in the struct rte_eth_txconf datatype) set to zero.
See the "Configuration of Transmit and Receive Queues" section in the *Intel® DPDK Programmer's Guide* for more details.
