🎀 ARGUMENTS 🎀

  • hw — the hardware structure that contains the filter list 🦋 this is the source-of-truth bestie, the one holding all the fdir filters, and she's gonna go look at it.
  • cmd — the ethtool command data structure that receives the filter data 💌 so hw has the tea, and cmd is the one getting told everything. it's giving passing notes in class.

  • Returns 0 on success 🎉
