📦 version 7.3.1, in nixpkgs unstable

✨ rsi_mac80211_get_antenna ✨

okay bestie, so this is a page from the Kernel API Manual (yes, the kernel has lore too 💅) and today's main character is rsi_mac80211_get_antenna — the function that is used to configure tx and rx antennas. literally what it says on the tin, no cap 🦋

🎀 SYNOPSIS 🎀

int rsi_mac80211_get_antenna (struct ieee80211_hw *hw , int radio_idx ,
       u32 *tx_ant , u32 *rx_ant );

that's the whole vibe check right there — four args, one int coming back at you 🌸

🫶 ARGUMENTS 🫶

  • hw — pointer to the ieee80211_hw structure. you know, the big one 👑
  • radio_idx — radio index. which radio we're talking about, iykyk
  • tx_ant — bitmap for tx antenna 📡 the sending one
  • rx_ant — bitmap for rx antenna 📡 the receiving one
not me stressing that tx_ant and rx_ant are bitmaps and not just numbers — keep that energy, bestie, it matters 💀

⭐ RETURN ⭐

0 on success, negative error codes on failure. so like, zero is the slay, anything negative is the situation 😭

🌈 SEE ALSO 🌈

the kernel file it lives in is literally right here:

./drivers/net/wireless/rsi/rsi_91x_mac80211.c

and that's the page, bestie 🧚💜 this whole thing came out of ./drivers/net/wireless/rsi — Kernel API Manual, dated October 2026. go configure those antennas, periodt 🔥
