mhi_queue_skb(9)

💖 NAME 💖

okay so this is mhi_queue_skb(9) from the Kernel API Manual, and it's literally the function to Send or receive SKBs from client device over MHI channel 🦋💅

🌸 SYNOPSIS 🌸

here's the exact signature, bestie — no cap, type it like this:

int mhi_queue_skb (struct mhi_device *mhi_dev , enum dma_data_direction
       dir , struct sk_buff *skb , size_t len , enum mhi_flags mflags );

🎀 ARGUMENTS 🎀

• mhi_dev — device associated with the channels. this is your main-character device 💖
• dir — DMA direction for the channel. which way the tea is flowing ✨
• skb — buffer for holding SKBs. the little suitcase for your packets 🎀
• len — buffer length. how much fits in the suitcase, literally 🦋
• mflags — MHI transfer flags used for the transfer. the settings/permission slips for the transfer 🌸
