Subject: RE: [dpdk-dev] [PATCH v2] net/axgbe: vlan support enabling in axgbe
Hi Yigit,
1. The Rx vlan filter set calls vlan_offload_set as shown below:
rx_vlan_filter_set() <-- app/test-pmd/config.c ...
rte_eth_dev_set_vlan_offload(uint16_t port_id, int offload_mask)
<--lib/librte_ethdev/rte_ethdev.c { ...
ret = (*dev->dev_ops->vlan_offload_set) <-- this calls the respective driver's
func ...
}
2. The tx vlan check for flags and based on same it add/remove as shown below
the code flow:
tx_vlan_set(portid_t port_id, uint16_t vlan_id) <-- app/test-pmd/config.c ...
rte_eth_dev_info_get(port_id, &dev_info); <-- collect flags from driver
check capability DEV_TX_OFFLOAD_VLAN_INSERT ...
ports[port_id].tx_vlan_id = vlan_id; <--insert vlan to respective port id
Note: Also attached logs to check call for filter flow and strip on/off.
In strip log by default the strip is off and hence header shown when sent vlan
pkt from pktgen running in other device and in strip on the header is getting
removed.
Let me know if you need more logs.
Note: In pkt-gen log, the log captured for filtering with different vlan
settings to check data flow post addition/removal of vlan in both side (pkt-gen
and DUT, device under test).
Thanks & regards

There is no "VLAN" feautre defined [1], but "VLAN filter" [2] & "VLAN offload"
[3], and in this patch I guess you mean both.
But for "VLAN offload", I don't see the driver sets "PKT_RX_VLAN" or
"PKT_RX_VLAN_STRIPPED" mbuf flags at all. And it doesn't use 'mbuf.vlan_tci' at
all, in both Rx & Tx. Are you sure VLAN offload supported by driver?
And for Tx, driver still uses 'PKT_TX_VLAN_PKT' which is deprecated, can you
please replace it with 'PKT_TX_VLAN'?
