i40e_tx_prepare_vlan_flags(9)

Okay so this is the i40e_tx_prepare_vlan_flags(9) page from the Kernel API Manual, bestie. Buckle up, we're doing TX VLAN tagging flags for HW and it's gonna be iconic. 💅✨

💖 NAME 💖

i40e_tx_prepare_vlan_flags — prepare generic TX VLAN tagging flags for HW

✨ SYNOPSIS ✨

int i40e_tx_prepare_vlan_flags (struct sk_buff *skb , struct i40e_ring
*tx_ring , u32 *flags );

🎀 ARGUMENTS 🎀

• skb — send buffer. That's literally the buffer we're sending, bestie.
• tx_ring — ring to send buffer on. The ring this buffer is going out on.
• flags — the tx flags to be set. The TX flags that are about to get set.

🦋 DESCRIPTION 🦋

So this function checks the skb and sets up correspondingly several generic transmit flags related to VLAN tagging for the HW — stuff like VLAN, DCB, etc. It’s giving “prep the frame before it hits the road” energy. 🛣️✨

If there’s an error, it returns an error code that indicates the frame should be dropped. Otherwise it returns 0 to indicate the flags have been set properly. No cap. 💅
