ENUM DCBNL_TC_ATTRS(9)

💖 NAME 💖

Okay bestie, this is enum dcbnl_tc_attrs(9) from the Kernel API Manual — aka the DCB Traffic Class attributes enum. It's giving very niche networking fairy energy, and we're obsessed. 🧚✨

🦋 SYNOPSIS 🦋

enum dcbnl_tc_attrs {
    DCB_TC_ATTR_PARAM_UNDEFINED ,
    DCB_TC_ATTR_PARAM_PGID ,
    DCB_TC_ATTR_PARAM_UP_MAPPING ,
    DCB_TC_ATTR_PARAM_STRICT_PRIO ,
    DCB_TC_ATTR_PARAM_BW_PCT ,
    DCB_TC_ATTR_PARAM_ALL ,
    __DCB_TC_ATTR_PARAM_ENUM_MAX ,
    DCB_TC_ATTR_PARAM_MAX

};

🎀 Constants 🎀

• DCB_TC_ATTR_PARAM_UNDEFINED — the unspecified attribute, literally there to catch errors. It's the "oops, bestie, wrong turn" option. 🙈
• DCB_TC_ATTR_PARAM_PGID — (NLA_U8) the priority group the traffic class belongs to. Valid values are: 0-7. Slay, but keep it in range. ✨
• DCB_TC_ATTR_PARAM_UP_MAPPING — (NLA_U8) the traffic class to user priority map. Caveat: some devices may not support changing the user priority map of a TC. Not everyone gets the glow-up, iykyk. 💅
• DCB_TC_ATTR_PARAM_STRICT_PRIO — (NLA_U8) the strict priority setting. The values are: 0 - none, 1 - group strict, 2 - link strict. Pick your fighter. 🔥
• DCB_TC_ATTR_PARAM_BW_PCT — optional — (NLA_U8) if the device supports it and it's not configured to use link strict priority, this is the percentage of bandwidth of the priority group this traffic class belongs to. Math but make it bandwidth. 🍓
• DCB_TC_ATTR_PARAM_ALL — (NLA_FLAG) all traffic class parameters. The whole squad, together. 👑
• __DCB_TC_ATTR_PARAM_ENUM_MAX — the manpage just says -- undescribed --, so bestie, that's all the lore we're getting. No cap. 💀
• DCB_TC_ATTR_PARAM_MAX — also -- undescribed --. Mysterious main character energy, honestly. 🌈
