Based on hns3 network engine, in order to configure hardware VLAN insert
offload in Tx direction, PMD driver reads the VLAN tags from the
vlan_tci_outer and vlan_tci of the structure rte_mbuf, fills them into
the Tx Buffer Descriptor and sets the related offload flag for every
packet.
Currently, there are two VLAN related problems in the 'tx_pkt_burst' ops
implementation function:
1) When setting the related offload flag, PMD driver inserts the VLAN
tag into the position that close to L3 header. So, when upper
application sends a packet with a VLAN tag in the data buffer, the
VLAN offloaded by hardware will be added to the wrong position. It is
supposed to add the VLAN tag from the rte_mbuf to the position close
to the MAC header in the packet when using VLAN insertion.
And when PF PVID is enabled by calling the API function named
rte_eth_dev_set_vlan_pvid or VF PVID is enabled by hns3 PF kernel
ether driver, the VLAN tag from the structure rte_mbuf to enable the
VLAN insertion should be filled into the position that close to L3
header to avoid to be overwritten by the PVID which will always be
inserted in the position that close to the MAC address.
2) When sending multiple segment packets, VLAN information is required
to be filled into the first Tx Buffer descriptor. However, currently
hns3 PMD driver incorrectly placed it in the last Tx Buffer
Descriptor. This results in VLAN insert offload failure when sending
multiple segment packets.
This patch fixed them by filling the VLAN information into the position
of the Tx Buffer Descriptor.
