ixgbe_device...s_autoneg_fc(9)
π ixgbe_device_supports_autoneg_fc(9) β from the Kernel API Manual, bestie π«Ά
okay so picture this: you're deep in the Linux kernel docs, specifically the Kernel API Manual, and you've stumbled onto this little function called ixgbe_device_supports_autoneg_fc. yes the name is a mouthful, no we're not changing it, it's iconic. let's get into it β¨
πΈ NAME πΈ
ixgbe_device_supports_autoneg_fc β literally just "check if phy supports autoneg flow control". that's the whole vibe check. π
β¨ SYNOPSIS β¨
bool ixgbe_device_supports_autoneg_fc (struct ixgbe_hw *hw );
she returns a bool, she takes one pointer, she's lowkey minimal about it. periodt.
π ARGUMENTS π
hwβ pointer to hardware structure. yes bestie, the whole hardware struct, handed to you like a lil gift. π
π¦ DESCRIPTION π¦
okay so here's the tea β β there are several phys out there that just do not support autoneg flow control. not their fault, they were built like that, we don't judge. π
so what does this function do? she checks the device id β that's the whole move β to see if the associated phy supports autoneg flow control. that's it. that's the function. no cap, she's doing one job and doing it well. π
think of her as the bouncer at the club: is this phy on the list? true or false, no in-between. πͺβ¨
