       , unsigned int base , unsigned int len , unsigned int hdrsize );

🦋 ARGUMENTS 🦋

• req — RPC request to prepare. this is the request bestie is setting up 💅
• pages — vector of struct page pointers. the page squad that the reply payload is headed into 🫶
• base — offset in first page where receive should start, in bytes. yes, bytes, keep that in mind ✨
