💅 ieee80211_sta_bw_capability — get STA's bandwidth capability

okay bestie so you're deep in the kernel API manual, section 9, and we're looking at ieee80211_sta_bw_capability — yes that's a whole mouthful, drink some water. ✨ This one's literally just "hey, how much bandwidth can this STA actually handle?" and it's lowkey iconic for it.

✨ SYNOPSIS ✨

enum ieee80211_sta_rx_bandwidth ieee80211_sta_bw_capability (struct
       link_sta_info *link_sta , enum nl80211_band band );

yes the signature wraps like that, she's a long one, we don't judge 🎀

🌸 ARGUMENTS 🌸

• link_sta — the (link) STA you want the capability for 🫶 that's the main character of this call ngl
• band — the band you're asking about the capability on. like, which band. specific band energy 💅

⭐ RETURN ⭐

the maximum bandwidth supported by the STA. that's it, that's the answer. the ceiling. the limit. the "how much can she take" number 💖

no cap, that's the whole return value — max bandwidth, supported by the STA.
