ice_tx_prep...an_flags_dcb(9)

💖 NAME

okay so bestie, welcome to the Kernel API Manual page for ice_tx_prepare_vlan_flags_dcb — the header truncates it as ice_tx_prep...an_flags_dcb(9), which is giving dramatic ellipsis energy, but we move. 💅

ice_tx_prepare_vlan_flags_dcb — prepare VLAN tagging for DCB. That's it, that's the name, no cap. ✨

✨ SYNOPSIS

void ice_tx_prepare_vlan_flags_dcb (struct ice_tx_ring *tx_ring , struct
       ice_tx_buf *first );

🎀 ARGUMENTS

• tx_ring — the ring to send the buffer on. literally the lane your buffer is riding. 🛣️
• first — pointer to struct ice_tx_buf. yes bestie, it's a pointer to that struct. 🫶

🦋 DESCRIPTION

okay so real talk: do not call this if the outer VLAN is software offloaded — because the VLAN tag will already be configured with the correct ID and priority bits. that's the whole caveat, and it's important, ngl. 🙈 so if that outer VLAN is already software-offloaded, this function is not the one, periodt.
