This was reverted, more or less, to print only a warning: https://git.kernel.org/pub/scm/linux/kernel/git/davem/net.git/commit/?id=6e237d099fac1f73a7b6d7287bb9191f29585a4e
Jouni fixed this already in hostapd but we also need a fix for kernel so that old hostapd versions continue to work: https://w1.fi/cgit/hostap/commit/?id=a2426829ce426de82d2fa47071ca41ea81c43307 Jouni also found a similar problem with mesh: https://w1.fi/cgit/hostap/commit/?id=963d3149abfcbab5b83f9023bc50321f777360d1
See above for the kernel revert to let old hostapd versions continue to work (properly only on little endian platforms) when they don't have these fixes.
And Johannes already submitted a revert related to wpa_supplicant: [net] Revert "net: core: maybe return -EEXIST in __dev_alloc_name" diffmboxseries https://patchwork.ozlabs.org/patch/843863/
That was applied.
And with ath10k I'm now seeing this: [ 133.175508] WARNING: CPU: 2 PID: 1743 at net/mac80211/agg-tx.c:315 ___ieee80211_stop_tx_ba_session+0x1ab/0x280 [mac80211]
Just sent a fix for this, kinda a merge/patch failure.
