π ieee80211_s..._iftype_data(9)
okay bestie, welcome to the Kernel API Manual β¨ this is the page for ieee80211_s..._iftype_data(9) and honestly? it's giving short-but-iconic. no cap, we're gonna get through it together π«Ά
πΈ NAME πΈ
ieee80211_set_sband_iftype_data β set the sband iftype data array π
like, that's the whole gig. it sets the sband iftype data array. main character energy fr fr π
β¨ SYNOPSIS β¨
ieee80211_set_sband_iftype_data (sband , iftd );
that's it, that's the call π (spacing is exactly how the page has it, don't come for me π)
π¦ ARGUMENTS π¦
sbandβ the sband to initialize. bestie, this is the one getting set up πΈiftdβ the iftype data array. this is the data that goes in π
lowkey important: this is part 1 of the page, so don't close the tab β more is on the way π₯
π SEE ALSO π
okay bestie, this is the part where the page lists literally everyone it knows. it's giving massive group chat energy π every single one of these is a real cross-reference, so if you're lost, just tap one and keep vibing. no cap, this is a long list, but we're getting through it together.
