cxgb4_ethofld_send_flowc(9)

💖 NAME 💖

okay so bestie, this page is cxgb4_ethofld_send_flowc(9) from the Kernel API Manual, and it's literally about sending an ETHOFLD flowc request to bind eotid to tc. The whole vibe is bind/unbind: tie an ETHOFLD tid to a traffic class, or free it. 🫶✨

✨ SYNOPSIS ✨

this is the exact signature, no cap:

int cxgb4_ethofld_send_flowc (struct net_device *dev , u32 eotid , u32
tc );

🎀 ARGUMENTS 🎀

• dev — the netdevice. That's the network device bestie we're working with. 💻
• eotid — the ETHOFLD tid to bind/unbind. This is the id getting tied to, or freed from, a traffic class. 🎀
• tc — traffic class. If it's set to FW_SCHED_CLS_NONE, then it unbinds the eotid. 💅

🦋 DESCRIPTION 🦋

So what actually happens? You send a FLOWC work request to bind an ETHOFLD TID to a traffic class. That's the main character move. ✨

If tc is set to FW_SCHED_CLS_NONE, then the eotid is unbound from a traffic class. That's the unbind era, periodt. 💜

🫶 cute sign-off: the source/version tag on this page is ./drivers/net/ethernet/chelsio..., the date is October 2026, and the title slash manual name is cxgb4_ethofld_send_flowc(9). byeee, go bind those TIDs responsibly 💜✨
