🌸 SYNOPSIS 🌸

int ixgbe_read_posted_mbx (struct ixgbe_hw *hw , u32 *msg , u16 size ,
       u16 mbx_id );

  • hw — pointer to the HW structure. the hardware girlies know. 🫶
  • msg — The message buffer. this is where the message goes to live its best life.
  • size — Length of buffer. yes ma'am, we respect boundaries here.
  • mbx_id — id of mailbox to write. pick your mailbox, bestie, there are options.

💜 DESCRIPTION 💜

okay so here's the tea: ixgbe_read_posted_mbx returns SUCCESS if it successfully received a message notification and copied it into the receive buffer.

that's it. that's the whole plot. she waits, she receives, she copies, she returns SUCCESS, she leaves. no drama, no cap. ✨

ngl the double condition is important — it's notification received AND copied into the receive buffer, both, together, as a package deal. don't @ me.
