lpfc_least_capable_settings(9)

okay so bestie, welcome to the Kernel API Manual — today’s main character is lpfc_least_capable_settings(9) 💅✨

💖 NAME 💖

lpfc_least_capable_settings — helper function for EDC rsp processing 🛠️✨

🦋 SYNOPSIS 🦋

void lpfc_least_capable_settings (struct lpfc_hba *phba , struct
fc_diag_cg_sig_desc *pcgd );

🎀 ARGUMENTS 🎀

• phba — pointer to lpfc hba data structure. iconic little pointer, no cap 🫶
• pcgd — pointer to congestion detection descriptor in EDC rsp. yes bestie, that descriptor right there 💅

🌸 DESCRIPTION 🌸

okay so the way that this helper routine works: it determines the least capable setting for congestion signals, signal freq, including scale, from the congestion detection descriptor in the EDC rsp. then the routine sets phba values in preparation for a set_featues mailbox. periodt 💖
