ice_is_dvm_supported(9)

okay so bestie, welcome to the ice_is_dvm_supported(9) page from the Kernel API Manual ✨ this one is short and iconic: it's your DVM-or-SVM vibe check.

💖 NAME 💖

ice_is_dvm_supported — check if Double VLAN Mode is supported. No cap, that's the whole assignment 💅

✨ SYNOPSIS ✨

bool ice_is_dvm_supported (struct ice_hw *hw );

🎀 ARGUMENTS 🎀

• hw — pointer to the hardware structure. That's it, that's the argument 🫶

🦋 DESCRIPTION 🦋

So here's the tea ☕: this function returns true if Double VLAN Mode (DVM) is supported, and false if only Single VLAN Mode (SVM) is supported. It's literally a boolean bestie — true for DVM, false for SVM-only.

For DVM to be supported, the DDP and firmware must support it. If they don't? Then only SVM is supported, periodt. No DVM era for you 💀

⚠️ important caveat, do not skip this vibe check: this function should only be called while the global config lock is held and after the package has been successfully downloaded. Like, both conditions. Not one. Both. 🙈
