💀 DESCRIPTION 💀

okay so what does she actually do: i40e_free_pf frees the i40e_pf structure and the devlink — and that devlink was allocated by devlink_alloc 👑 so like, it's the cleanup bestie. the closing-the-loop moment. the "we're so back → it's over" arc 🔥

literally: i40e_pf gets freed, devlink gets freed, done. iconic behavior, no notes 🧚

real talk though — this is the free side of the story, so the matching alloc side is where the memory came from in the first place (see SEE ALSO below, iykyk 👀)
