e1000e_get_s...fiber_serdes(9)

Manual vibe check: this is e1000e_get_s...fiber_serdes(9), from the Kernel API Manual — yes, the truncated title is the title, and we are keeping it exactly like that, bestie.

✨ NAME ✨

e1000e_get_speed_and_duplex_fiber_serdes — Retrieve current speed/duplex. That is the whole name-and-purpose moment, and it ate. 💅

🌸 SYNOPSIS 🌸

s32 e1000e_get_speed_and_duplex_fiber_serdes (struct e1000_hw *hw , u16
*speed , u16 *duplex );

💅 ARGUMENTS 💅

• hw — pointer to the HW structure.
• speed — stores the current speed.
• duplex — stores the current duplex.

🦋 DESCRIPTION 🦋

okay so this function sets the speed and duplex to gigabit full duplex for fiber/serdes links — and the original is very clear that this is the only possible option. So yes: fixed-config main character energy, no options menu, periodt. ✨
