Hello,
I have a problem about ixgbe's Rx Burst Bulk Alloc function.
When I set .rx_free_thresh of rte_eth_rxconf to 32 to enable Rx Burst
Bulk Alloc function,
ixgbe can no longer detect ip/udp checksum error.
Also, when I enable Rx Burst Bulk Alloc function, and set
.hw_vlan_strip of rte_eth_conf to 1,
the PKT_RX_VLAN_PKT bit of pktmbuf->ol_flags is off even if it is a vlan packet.
Could someone can tell me why?
Thanks a lot!
