okay so bestie, welcome to the Kernel API Manual corner where the main character is batadv_hardif_is_iface_up(9) ✨. This function checks whether the underlying net_device of a hard interface is up — that’s the whole vibe check, no cap 💅.

🦋 SYNOPSIS 🦋

it’s giving signature realness:

bool batadv_hardif_is_iface_up (const struct batadv_hard_iface
       *hard_iface );

🎀 ARGUMENTS 🎀
